Unable to Contact DHCP Server~Limited or No Connectivity~Cannot Assign Network Addres

Q: Unable to Contact DHCP Server~Limited or No Connectivity~Cannot Assign Network Addres

Hi There Everyone at TechGuy! I am desperate for some HELP...Please?..........PRETTY PLEEEAAASSEE ???
Now,..Before i Continue Please First Be Sure to Read Fully as I did Some Google Searching & Tried Some Forum Fix It Options that I Found, which havent worked at all but I will leave you all info as well as some screen shots.
Second...Please know that I am not Very Computer Savvy or Knowledgable. Well,....a Little for a Home User but with the Operating System, NOT with this problem & networking, routers, modems, IP addresses & DHCP !! Networking is DEFINITELY NOT my area of expertise So Please Handle with Care. lol. THANKS & HUGS in Advanced!

ok,
The Problem.
We have a Desktop computer as well as a Lap Top,..both Running WINDOWS XP. The Lap Top is Wireless with a LINKSYS Wireless Card & the Desktop has the MOTOROLA Modem & a LINKSYS Router & we are BROADBAND Connected.
Both were Running & Working just fine & they were Both Accessing the Internet just fine...until 3 days ago when the Man in the house had to turn off the house power to find & replace a circuit breaker for the fritzing out Microwave & we turned off both computers before he did this. When the power was put back on, the Desktop Computer was back to its normal fine self & running perfectly. The Wireless Lap Top on the other hand was not.
The Wireless Laptop Popped Up with a Yellow Explaination Mark over the Double Computer Icon in the Bottom Right Task Bar...Near the Clock, with a Message in the Task Bar Stated :: "LIMITED OR NO CONNECTIVITY" "THE PROBLEM OCCURRED BECAUSE THE NETWORK DID NOT ASSIGN A NETWORK ADDRESS TO THE COMPUTER". With this Message, the Lap Top's Battery Light is now Constantly Blinking as well...even though it sits on a desk & is always plugged into an outlet electronically??? Dont know if its related, but wanted to mention it just incase.
...Our first thought was that maybe it was now a blown fuse or something since the computer is electrically powered.....but We checked all fuses, & the outlet & all seems fine....
SO,
I Tried to do the Repair Link they Provide & got back a Message that Stated ::
"WINDOWS COULD NOT FINISH REPAIRING THE PROBLEM BECAUSE THE FOLLOWING ACTION CANNOT BE COMPLETED: RENEWING YOUR IP ADDRESS. CONTACT THE PERSON THAT MANAGES YOUR NETWORK."
I then Ran IP CONFIG / ALL on Both the Wireless Lap Top as well as the Desktop, & Screen Shot Photos of Both Will Be Attached to this Message...The One for the WIRELESS LapTop is the BLACK Colored Picture Attachment & the One for the DESKTOP is the MAGENTA Colored Picture Attachment.
I also Ran IPCONFIG /RENEW & it Comes back with a Message Stating ::
"UNABLE TO CONTACT YOUR DHCP SERVER. REQUEST TIMED OUT"
I Ran a Command Found on Google for Repairing Corrupt TCP/IP Stack ~ Command "netsh int ip reset resetlog.txt" & it Made the Yellow Explanation Mark on the Double Computer Icon in the Taskbar with the Pop Up Message Stating Limited or No Connectivity, Go Away & I was So Excited thinking that it was fixed, but NADA...We still could not get on the internet. When i try to i get the Cannot Connect to Internet Explorer & When i Run the Repair i get an Error 12007 ??
I then also Ran a Command for Reseting the Winsock ~ Two of them...."netsh winsock reset" & "netsh winsock reset catalog" & restarted, but NADA.
Now I also noticed that the IP address is 169.254, which it normally isnt....to my knowledge?
Now, i also took a peak at the event log, & in there, from the day the power was turned off was a "DHCP Warning" & it said ::
"Your Computer Automcatically Configured IP Address for Network Card with Network Address 0004 5AC94EA. The IP Address being used is 169 254 45 251"

OH, I also Checked that the Following SERVICES were Started on Both the Lap Top & Desktop. There were, of course, Other Services Other then these that were indeed Started but per a Google Search & Forum Reply & Response, Someone Said to Check these & so i did & these were indeed Started. If there are Any Others i Need to Check on for sure, Let me Know.
• COM+ Event System • Computer Browser • DHCP Client • DNS Client • Network Connections • Network Location Awareness • Remote Procedure Call (RPC) • Server • TCP/IP Netbios helper • Wireless Zero Configuration • Workstation

Now, i also want to note that although the Lap top was connecting to the internet fine before the power issue, it did occasionally experience these limited or no connectivity issues before, but in the past we were able to renew the IP address with no problems! Now we also think, but arent sure, that the Wireless Card was never installed right to begin with, & we didnt install it by using the Wireless Network Setup Wizard either.
This then leads me to telling you that in non computer terms & without definitive knowledge; that the Lap Top & the Desktop are not really like "Networked"...i dont think. We dont share anything between them, nor can we view anything off eachother...whether this is being Networked or not...i really dont know & i dont know if its even needed knowledge...i just wanted to be thorough & thought Id mention it.
& Maybe i should note that another person in the household attempted to set up a new network connection with the network setup wizard...They did it both on the Lap Top first...which said to run the Network Wizard on any other computers as well & so she did it on the desktop as well & the desktop came back saying "CANNOT COMPLETE THE NETWORK SETUP WIZARD. OTHER COMPUTERS CANNOT CONNECT TO THE INTERNET THROUGH THIS COMPUTER."
& OH,...this may be Important.
About a year ago now, Out of the Blue, the Desktop as well as the Lap Top Could Not Get on the Internet when the WINDOWS FIREWALL was Turned ON, so we Turned it Off on both the Desktop & the Lap Top & It Remains on OFF today.
Well,....I think I've given you all I know & All that I can for now. I So Very Much Hope Someone Out there can Spare Some of Their Time & Help Me. & again....Please Know Im Not Computer Knowledgable when it comes to Networking Issues So I will Need Help with any Steps or Instructions.
& OH I am SO THANKFUL Already to Any of you that will Give your Time to My Annoying Issue & to Helping Little Lost Me Out. Really.....Im ETERNALLY GRATEFUL.
​MANY THANKS & HUGS !!!! ~ Corey

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello. I just moved to Auckland, NZ from the USA to go to school at the university here, and am having a problem connecting to the internet in the university residence hall in which I am living.
Wifi is not available in the residence halls, so we need to use an Ethernet cable. When I plug in my computer, the network adapter icon says “Identifying...” for a while then settles on “Unidentified Network” with no internet access, the IP is 169.x.x.x
When I try to release and renew the IP, it says “unable to contact your DHCP server, request has timed out"
I've tried multiple Ethernet cables, both brand new.
I tried connecting to a port in a friend's room in the same building, and even in a classroom on campus, and both had the same result.
Naturally after all that I assumed my NIC somehow died overnight while I traveled here, so I went to a computer repair shop expecting to have some hardware replaced, but we plugged it in there and it worked immediately so they weren't sure what to tell me.
I've gone through pages of old threads at this forum and others like it, trying solutions but having no luck.
I've power cycled my computer, obviously I can't power cycle the whole network as it's for 200 people, but the IT people here have tried resetting it for me on their end as best they can.
No network bridges
I've reset tcp/ip stack and winsock

Hello all, long time reader, first time poster. First let me start by saying i've spent the better part of a week navigating this and other forums and an answer to my question. So here it is.

I recently built a new computer for my parents via newegg. Got everything up and running and went to install their copy of windows xp home. I get everything installed and all the drivers off the install cd's incuded. When i sttempt to connect to the internet i get " An error occured while renewing interface Local Area Connections 2: unable to contact your DHCP server. Request has timed out."

What i've tried:
- Reboot comp and modem.
- Check cableing.
- Uninstall and Reinstall mobo network driver. (MOBO - http://www.newegg.com/Product/Produc...82E16813130187)
- Updating the network driver via flash drive and a working computer.
- Winsock and netsh int ip fix.
- Returned mobo and replaced with same model.
- Removed HDD, connected to a working PC, installed winxp, everything worked. Took out the HDD, installed into non-working pc. Same issue as before.

Please help.
 

A:Unable to contact your dhcp server. (I've tried everything!)

It would be helpful if you could tell us how you connect to the Internet. Are you on cable, DSL, dialup? We also need to know who your ISP is, what your brand and model of modem are, etc. Without more information, there isn't any way to resolve your problem.

Hi,
I'm using Windows 8.1 on a HP 64 bits.
I'm unable to connect via my Ethernet Cable to the local Network.

I get the message: "Ethernet" doesn't have a valid IP configuration, and the connection says: "Unidentified Network - Limited".

My DHCP server has the following IP address: 192.168.2.1

Command ipconfig says that:
Ethernet adapter Ethernet:
Autoconfiguration IPv4 Address: 169.254.175.104
This IPC address given by the autoconfiguration is wrong!!!

I tried a few fixes, according to what I've found on Internet.

1. First try

ipconfig /release
ipconfig /renew
Doesn't fix my problem.

2. Another try

netsh windows reset catalog
netsh int ipv4 reset reset.log
Doesn't fix my problem.

3. Another try

netsh interface ipv4 show inter
=> gives me: idx = 20 for Name="Ethernet"
then: netsh interface ipv4 set interface 20 dadtransmits=0 store=persistent
then: disable startup type for service "DHCP client", stop the service, unplug Ethernet cable
reboot
then: startup type = automatic for service "DHCP client", restart the service, plug Ethernet cable
Doesn't fix my problem.
What can I do now?!!!
Thanks for any help.

I have a Dell 570 Inspiron desktop running win7 home premium w/ a 64 bit OS. I have Frontier dsl with a Westell 327W modem and a netgear router. Two desktops are connected to the internet...one through the modem and the Dell 570 through the router. I also run laptops through the router w/no problem. This morning the dsl went down, and when it came back up, the Dell 570 would not connect. i tried Diagnosing Connection Problems, and I'm told to turn off the modem/router (which I have done a gazillion times). When I look at Network Connections in the Control Panel, It tells me I have an unidentified network and can't connect. I read through some forums earlier, and found that releasing and renewing ipconfig often corrects the problem, and that's when I got the message that 'An error occurred while nenewing. Local Area Connection unable to contact DHCP server.' This set up has worked for the past year and a half. I looked at the network adapter, and it says it's working properly. I changed the cables going to the machines, and they both work on this computer. The only change made to the computer was to install McAfee security center through AOL yesterday, but the set up worked all yesterday and last night. I am not very techie...i can make some software sing, but when it comes to hardware and networking issues, I'm not too bright. Any help you can provide would be much appreciated. Problems like this make me crazy.
 

A:Unable to contact DHCP Server

After uninstalling McAfee run the McAfee Removal Tool.

Open a (black) Command Prompt window:
Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

After a BSOD incident which now appears to be remedied, my desktop cannot connect to the internet. I receive a pop-up "This connection has limited or no connectivity....." etc. When I perform start>run>cmd>ipconfig /release and then /renew, I receive the message "unable to contact your DHCP server". A laptop connect to the same router and modem is working just fine (I'm on it now). I have already done the following based on advise from other sites:

-confirmed my DNS Client is Started and set to Automatic
-confirmed my DHCP Client is Started and set to Automatic
-downloaded and performed both lspfix.exe and winsockxpfix.exe
-Reset TCP/IP with the netsh command and tried the netsh dump
-Confirmed I do not have a network bridge running
-disabled my 3rd party firewall
-reset my modem and router
-checked cables
-deleted & re-installed the NIC
-Start >> run >> services.msc >> DHCP client >>go to "Dependencies" and
checked for the following items:

AFD Networking Support environment
Net BIOS over TCP/IP
TCP/IP Protocol Driver
-Reset winsock in the command prompt using netsh winsock reset

I am running 32-bit XP with SP3. Please ask for any other details required to help me resolve this.

A:Unable to Contact your DHCP Server

I would try a different NIC...the trail seems to lead that way.

These are not expensive and should allow more definitive troubleshooting.

netsh winsock reset
After restarting, it worked however I would have a similiar issue but at increased intervials until 2 days ago. I logged on and the problem didn't go away. It was also when it ilustrated the no internet acess warning when it can detect my extender I use for ethernet but can't get internet.

A:unable to contact DHCP server

Try This

Disable the XP firewall and try again. If it works, set it back up but as part of a LAN.
From the command prompt, ping 127.0.0.1 and see if you get OKs back. That means your network adapter is probably Ok.
Next, run the Wireless Network Setup and see if it recognizes the network adapter and can detect your LAN. Unless you've changed your WEP/WPA passwords recently this should work.
Run a virus scan and see if you picked up a bug.

Let me know how it goes

I would appreciate any help you can offer here. I have a desktop computer directly connected to a cable modem. It was working perfectly fine the other day (it was connected to Comcast). Since then I have moved, and tried to connect it to another cable modem (this time it's a Time Warner modem). I keep getting the "limited connectivity" error and when I try to release and renew the IP address, I get the error "unable to contact your DHCP server. Request has timed out." I hooked it to my laptop and it works perfectly fine, so I know it's the desktop. Ipconfig of the desktop reveals a 169.254.xxx IP address. I have a Broadcom 440x 10/100 Integrated Controller. I have no network bridge. I have tried the following:

Updated the driver to the most recent
checked the DHCP settings in Services
uninstalled my McAfee virus scanner/firewall
reinstalled TCP/IP from windows\inf and rebooted and release and renew several times
reset the resetlog.txt and rebooted and release and renew several times
Is it possible that Comcast had it configured a specific way and now it won't work with the Time Warner cable modem? Is there a way to completely reset the settings? Is there a setting a can check or change?
Thank you.

I just replaced my XP desktop with a W7 laptop. I have had constant network issues. I have a home network with a Linksys WRT54G running DD-WRT. My old XP computer worked fine as do another laptop running XP and three other networked devices: Tivo (wireless), WD TV Live Hub (wireless), WD NAS (wired). The W7 laptop takes a long time to connect, first as a "Public Network" without internet capability. Then about one minute later (sometimes longer) as a "Home Network" without internet. Then about one minute later (sometimes never) with internet. After a few hours usage, the connection goes away, becoming a "Public Network". I cannot even access the router configuration page. The only way to get connected again is to physically unplug my router. My router is set up for DHCP and all devices, including the new W7 laptop, are configured to automatically obtain IP addresses from the router's DHCP server. I noticed that my IP address, in ipconfig /all, is "192.168.1.130(Preferred)." I haven't seen a good explanation yet for the "(Preferred)" part of it. When I try to renew the IP address, the error message is "unable to contact your DHCP server." In the router settings, I have tried to assign a "static lease", something I did with my XP desktop, but the IP address never takes. I have run a Microsoft fix for TCP/IP stack. I have uninstalled and re-installed my wireless adapter. The adapter drivers are up-to-date.... Read more

Ok, I've been fighting with this old desktop PC for a few days now and I'm at my wits end.

I've been trying (in vain) to connect a USB Wireless device to be able to use it off my wireless network. I have (2) other laptops and (1) other desktop connecting to the router with no issues.

For some reason, this old desktop keeps installing an Ethernet device (probably on the MB) and is automatically Configuring the IP address to that instead of the USB wireless device.

I've tried uninstalling the Ethernet device but it comes right back after I do a reboot. Even when I disable it, I still can not connect with my Wireless device.

Here's a screen shot when I do a ipconfig /all from the CMD prompt....

I just acquired two Gateway e6000 Pentium 4 2.4 Ghz XP PRO machines from work,(put out to pasture). They were setup to login to our domain at work and then after authentication you could access the internet. They were setup to receive an IP address from our domain controller and DNS was controlled by a local server. After bringing them home, I removed them from the domain and created a workgroup. I also set all TCP/IP properties to authenticate automatically and removed all instances for DNS. My current internet connection at home is a Westell Ethernet ADSL Modem C90-36R516 with a Cat5 cable going directly to the NIC. My existing home computer powers up and receives an IP address from the Westell without a problem but when I try attaching either of the Gateways, I get the error listed above. I have spent many hours troubleshooting this problem. I have tried the release/renew command, clearing the IP stack with netsh, checking security policy, clearing IP filtering, plus many, many other things. I was able to establish a connection and get on the internet with a Gateway but only after I gave the new Gateway a fixed IP address, default gateway and DNS entries that matched the current settings of my home computer. Correct me if I am wrong but I think I am issued a different IP by my Westell modem/router every time I boot up my computer. Or does this IP come from my ISP? And if the IP changes with every login, the Gateways will then not be able to login after a shutdown. Any idea... Read more

A:Unable to contact your DHCP server

Hi surffishermanca, and welcome to TSG.

Some ISPs (like SBC/ATT) configure the DHCP server on the modem to only give out a limit of one IP address, unless you sign up for some type of home networking plan. Try power cycling the modem when you switch computers.

EDIT: Thank you very much for all the details. Most people here would rather sift through bits of extra data than not having enough.

about an hour ago my 3month old Dell XPS Studio decided that i had "limited connection" to my router (wired). I have no idea what vista means by limited connection but i was unable to go on the internet with that computer. However the other computers on my LAN were fine (also wired)

I've tried rebooting the modem, router, pc.
I've done ipconfig /release and /renew afterwards.
I've done a few other cmd commands which resets my IPv6 and IPv4

still nothing. help anyone? thanks.

EDIT: update, i've tried some more stuff and upon ipconfig /renew it says there was an error with Loopback Pseudo-Interface 1 : The file was not found.

Well, let's do the official stack repair, since you didn't say exactly what you did.

TCP/IP stack repair options for use with Vista or Windows 7.

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.


Next, if that doesn't do it, I'd suggest a run with SFC since it's saying a file isn't found.

Hi there,
i've been having this annoying issue with my wireless connection, every now and then it gets disconnected and stays under "Limited Connectivity", i try to reset the IP and get the "unable to contact your DHCP server" problem, and i cannot do any of the ipconfig tasks due to the same error. The main problem is that i cannot have internet again until i restart the laptop, and even if i turn it off and back again, then it says "Windows Cannot find any Networks", or "try switching your wireless mode on", even though it's on and there are about 8 differenet wireless connections in here.
I know it's my laptop but is the wireless card damaged or something?.

I have a Toshiba Satellite A100 / SP3
with a
Intel(R) PRO/Wireless 3945ABG Network Connection
and im connected wireless to a WEP.
Drivers are updated and no configurations problems appear under device manager.
Thanks in advance for any help.

Hey i got similar problem.I have dell inspiron 1501 (Vista32) and routher Linksys WRt54G.
I keep getting "local only" and "limited conectivity".I realized that the problem is in my pc because the other pc's connect to the access point without problems.I tested the following:

plugged directly to the modem=no success
plugged to the wireless routher=no success

When i looked into the info from ipconfig command i get this ip:
autconfigured ipv4 169.254.15.197

Due to that i entered ip manually something like:
192.168.1.2
255.255.255.0 and default getaway 192.168.1.1
then tried with disabled ipv6
Still nothing.Then tried netsh int test reset ip and netsh winsock reset catalog without success!
The i upgraded my wireless card drivers and routher firmware just in case,reseted the routher to factory defaults and still nothing! I really dont know what could be the reason for that.Since i bought the laptop 1,6 year ago didnt had any problems.
I think everything started after i uninstaled Norton Internet Security and using Norton cleaning utility! I instaled Eset smart security and i started to get blue screen of dead! I wasnt able to log on to windows.After uninstalation i was unable to connect to internet.

Please Help

Hey,

I've been having problems connecting my laptop to the internet through wireless. When I plug it in with a cable it works fine. I also know my wireless works fine because i have other things attached to it.

When I try to connect it says limited or no connectivity, but the signal strength is excellent. I have tried to repair the problem but it then tells me it cannot renew my ip address. I've also tried the ipconfig /release then renew, and thats when it says about my DHCP. I have no idea what to do now.

Please help, but go slowly as I have no idea what half of it all means.

A:Unable to contact your DHCP server. Request timed out.

"Unable to contact your DHCP server" means that no Dhcp server responded to a request for an IP configuration. To begin troubleshooting you need to determine if there is an enabled Dhcp server on the network and the components of the network between the Dhcp server and the computer.

The connect the computer to the Dhcp server with the shortest possible path. Usually this means an ethernet cable between router and computer. If that works then add components one by one until you determine where the blockage/disconnect/defect is.

Hi all, got back from the beach and was greeted with internet troubles.

My desktop is the problem, running Windows XP SP2 and I have already tried a number of things:

Running ipconfig gives me a 169.254.***.** address, which I understand is a private IP or something.

Clicking "repair" on the right click drop down box on my local area connection gives me: "Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address."

ipconfig /release and ipconfig /renew gives me the following error:
"An error occurred while renewing interface Local Area Connection 4 : unable to contact your DHCP server. Request has timed out."

I have 2 other desktops and 2 laptops running on the exact same router, all are working like a charm. It appears to be something on the software side of my problematic desktop. I tried setting my IP manually by going to properties under Local Area Connection, then TCI/IP properties, but I don't know what to put as my DNS addresses. When I set my IP to what I know it SHOULD be and my default gateway to 192.168.0.1, my connection tells me everything is all right, but alas, no internet.

Any suggestions? And sorry if this is a repost, but the solutions for other people didn't work for me.

A:Internet troubles.. Unable to contact DHCP server

Try turning off your router for about 10 seconds and then reconnecting it. Also make sure you have no malware.

Does anybody have any ideas of how to fix this problem? I would really appreciate it!
 

A:Cannot renew IP Address, Unable to contact DHCP Server

1. Check the wifi /router end of the connection is configured to be a DHCP server
2. Beyond that there can be many variables. I think you're best approach:
=== > Backup the wifi / router settngs (most devices allow you to backup their config to your hard drive. Check the user manual)
===> Remove all the restrictions that were added via the config (e.g encryption, MAC address screening, etc.
3. Verify you and neighbors computer all connect and work when no restrictions.
4. Add back restrictions one-at-a-time and retest the computers (yours and neighbors) until they all work and all restrictions have been applied

L1 runs winXP SP3, L2 runs win7 Home Premium x64 SP1. Usually when L1 or L2 stops connecting, I turn off the wireless cards on both computers, power-cycle the modem and router, turn on the wireless cards, and then the laptops both connect. However, this workaround isn?t working for L2 anymore.

The event viewer shows errors such as the following:

Hello all, I was wondering if anyone can help me with my problem:

My sister's computer has decided to stop connecting to the internet since yesterday with the standard "Limited or No Connectivity" speech. We run 3 different laptops through the main computer's wireless network (which has the wired connection to the modem) and while the others are working fine, hers has the problem. Here are her specs:

Notebook: NEC Versa P8210
Notebook's Adapter: D-Link Wireless G DWA-110 USB Adapter
Modem: Belkin Wireless modem VoiP 802.11g gateway
Security: WEP (I tried changing it to WPA, but no computer could connect afterwards, so I switched back).
OPS: Windows XP Professional SP3

Things I have tried to do:

- enabled/disabled connection - no effect
- forced static IP address - This got me a full connection, but I couldn't ping or access the internet...?
- Ipconfig /flushdns, /release, /renew etc. - /renew get's stuck on "Unable to contact DHCP server"
- netsh winsock reset - no effect
- netsh int ip reset resetlog.txt - nothing happened
- restarting modem, computer, notebooks etc. - no effect
- checked & re-entered security key - no effect
- disabled firewall - no effect
Here's a copy of her ipconfig /all log:

ok so a buddy at work asked if i could look at a laptop. it was working fine apparently, but then out of the blue the internet will no longer work. so i bring it home, it hooks up to my Network, but no internet. i change it to a private network (though it automatically changes it back when i restart.) and still no internet. i've tried to manually and automatically change the IPv4. no avail. Looking at the Network and Sharing Center the middle icon says Identifying, but theirs an x between that and internet. *i have local only* when i try to resolve the problem it says Dhcp is not running tried restarting it, but it says it cant and that it didnt fix the problem. i dont believe its my modem or router my base pc runs on it fine. *plus this pc was doing this for said friend* also on one forum a guy stated that their were three different programs that were supposed to be running. he said to check them through cmd. i did. they were running. just not DHCP. i've had to restart this laptop about 20 times or so. i cannot change os *Vista (bleh)* nor do a system restore. *wish i could* i also put avira on the computer to check for viruses. *which it did* so that is on their. i also tried uninstalling his ethernet card, so its at Broadcom 590x 10/100 ethernet, i tried then to updated but the file didnt work. so i cannot even update that through the laptop. i have it hooked up through wireless and wired, but without internet. i have his windows firewall on, but i've tried ...

Info about my laptop:

HP Pavillion dv5-1000
Windows Vista SP2
Wireless a/g/n

Info about my network:

ISP: Optimum
The wireless network in our house is somewhat complicated, but is essentially:A modem which goes to a main router (ISP provided netgear)
That router broadcasts the network "NeroKingston"
One of the ethernet ports goes to a 24 port switch
2 more routers off of that (brand new from monoprice), used as WAPs
One in basement, one on main floor, one in attic

Every device one the network works (hardwired dvd player, Win7 machine, SONOS, android phones, macbooks, printers, iphones).

Info about my problem:

I will be connected to the network wirelessly and suddenly a page will take a very long time to load and finally says "cannot reach this page". If I try to do ipconfig /all (or maybe /renew, I forget) it says it is unable to contact my DHCP server.

If I disable and then re-enable the wireless adapter the problem resolves for a few more minutes, then dies out again.

When it is working my internet is realtively fast (30 megs up, 14 ms ping).

Any more info needed?

Hi!

My daughter got a virus on her laptop and after getting rid of it (I think all the way, it's hard to tell until I can update the anti-virus software) I can no longer connect her laptop to the internet.

I have had a problem in the past with having to reboot the server and all the computers in order for the computers (all of them in the house) to register new ip addresses. Normally, if I have one computer that refuses to connect even after a reboot of the entire system I can connect it thru LAN and it, bang, fixes itself. However, this time it is not working.

Not only will her wireless not connect but neither will the LAN. I have opened the cmd prompt and done an ipconfig/release and ipconfig/renew. Every time I do this I get the message:

"An error occurred while renewing interface Wireless Connection : unable to contact your DHCP server. Request has timed out."

I tried the "netsh int ip reset resetlog.txt" and it seemed to work fine.

I also tried the "netsh winsock reset" and it seemed to work fine as well.

I rebooted each time I attempted a fix. Still I am unable to connect to the internet. It says it is connecting locally, but will not connect to the actual internet. When I use the repair option it gives me the same messages over and over that do not work. It always leads back to the IP address.

Here are the specs on her computer and as much information as I can think of. Please let me know what else I can try to get her compu... Read more

Hi guys and gals,

i live in a student house, and we have a wireless network but my laptop can't connect to it. the lan works fine on my laptop, and my laptop can connect to a few of our neighbours unsecured networks. 3 other laptops in the house have no problem connecting to our wireless, but my laptop wont.

i opened a command prompt and did ipconfig/release then ipconfig/renew and this message came up: An error occurred while renewing interface Wireless Connection : unable to contact your DHCP server. Request has timed out.

when i try to connect to it in the list of available wireless networks, it acquires network address for a while, then says limited or no connectivity. i click repair, and it says " Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address. For assistance, contact the person who manages your network." ... and im the most computer literate person we've got

Hello,

I've been trying to connect to my home wireless router for a while now. I have one main computer and a laptop. The main computer works fine on the internet. The laptop does too if its connected by an ethernet cord. However, it refuses to connect to the wireless, saying that there is limited or no connectivity. I tried the ipconfig release and renew, but that's when it said "unable to contact DHCP server." I copied and pasted what was in the command box after the ipconfig below. How do I fix this problem to get my computer to connect to the wireless?

A:"unable to contact DHCP server" - problem connecting to wireless router

This morning my internet stopped working on my computer, and stays at "Limited or No Connectivity".

My computer is hooked up to a router with an ethernet cord, and that router is hooked up to my modem. There is also another computer hooked up by ethernet cord to the router, and I use the wifi a lot for my iPod. Both work fine, it's just the internet on my computer that doesn't seem to work.

So far I've ruled out any problems with the modem, router, ethernet cable and network card. I even went out and bought a new ethernet cable to see if that might fix the problem, but it didn't. Right now I'm in safe mode on my computer and the internet works fine, so the problem doesn't appear to be with my ethernet card.

I've tried unplugging and leaving both the router and modem for a few minutes, changing the cable to a different port on the router, hitting the reset switch on the modem and router, and ipconfig release/renew, but when I try ipconfig /renew it tells me "Unable to Contact Your DHCP Server".

After searching for quite some time and trying various things, my internet still won't work.
