Preferred Solution: DHCP Unable to connect

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.)

A: DHCP Unable to connect

Let's see this.
Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

Do NOT include the <> either, they're just to identify the values for substitution.

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 74.125.45.100

PING yahoo.com

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

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

I got a new desktop loaded with Microsoft Vista.

When I couldn't connect to my router (at home) I tried ipconfig /renew /reliease commands and got the following message:

"Unable to contact your DHCP server".

I brought my PC to work and it connected fine to the network there.

At home I use the modem/router provided by Verizon (FIOS). I tried several ethernet cables - so I am pretty sure it is not the cable.

BTW, other pc's at home are connected to the router, so the router is OK.

Any help is appreciated.

A:unable to connect to DHCP server

Check the setting on your Router which served as your DHCP as well. Make sure that the Router provides enough IP addresses for your home network.

I've got a pc (XP Pro) that I cannot get to connect to the internet.
I've set the network connection properties to get an ip address automatically but it keeps geting the default (I think or something else)...
I've tried setting it to a specific address in my network range and still notable to connect.

I've run all the latest updates for adaware, cwshedder, ewido, trying kaspersky now.

I've also run lspfix, and winsockfix but nothing.
The only thin that bothers me is in the Status window - its says Autmatic Private Addressing .. I was expecting to see address "Address assigend by DHCP"
This is a dial up pc which I've just added to my network to trouble shoot other things.
(I've set the connection to "Not dail a connection"

Any help direction appreciated.
 

A:Solved: Unable to set IP using DHCP - cannot connect

You don't mention alot of things - Is this wired or wireless? If this is wired have you tried different ports, cables and other equipment? If this is wireless did you address security I.E. setup all the correct things in the router/wap to enable it to connect?

I've run all the latest updates for adaware, cwshedder, ewido, trying kaspersky now.Click to expand...

(Did you do this part manually? These do connect to the internet to update so you may have internet ocnne ction but just not be able to browse? Or did you just use that dial up?)

Since you said this was dial up did you check all of the Network adapter settings to make sure its not disabled anywhere?

To Whom This May Concern:

I tried installing SP1 on a desktop Vista, with other windows updates, and my internet stopped working. My Xbox and another computer (XP SP2) work fine and haven't noticed a difference.

I've contacted my manufacturer, and they said uninstall everything. I did. There is one Windows Update and one Microsoft .NET Framework 3.5 SP1 that it won't let me uninstall. I've contacted my ISP and they said there's a problem between my modem and hub, but if that's the case, my other computers wouldn't be working either.

I've contacted Microsoft, several people, and after many procedures, concluded that I need a restore disk and set it back to factory settings. This is an absolute last resort.

Here are my specs:

AVG 8.5
Comodo Firewall

-enable and disable dhcp broadcast flag via regedit

-netsh resets

I've been trying for so long to connect internet to my laptop. After using the ipconfig /release, ipconfig /renew, it said "An error occured while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out". I am connecting with the cable directly from the modem. When I plug the cable inside my newer laptop, I have no problem connecting to the internet. My laptop that needs its ip address renewed has been turned off for around 2 years. So I'm guessing it may be considered a new connection by the DHCP server?

TCP/IP Properties "Obtain an IP address & Obtain DNS server address are already set to automatic. When I click on advanced it said DHCP is enabled.

When I look on Add/Remove Windows Components, the DHCP option isn't there.

The laptop is an HP ze4400 and the system is Microsoft Windows XP Version 2002. I'm using Comcast internet with an Arris modem. (Not sure if you really needed that info, but just to make sure.)

I'm not good at computer stuff, so please bare with me and give me a step-by-step example into solving this problem.

My parents computer has malware, spyware, or a virus. I removed as much as I could but there is still a presence on the computer.

Please provide more information in regards to what operating system you are using and the make/model of your PC. In addition, using TSG's Information Utility will be beneficial to us. Run the tool and provide the output in your next post.

Based off your commands, I'm assuming you're running Windows.
1. Hit the Windows key on your keyboard
2. Type cmd and hit Enter on your keyboard
3. In the black box that appears, type ipconfig /all > %userprofile%\desktop\ipcfg.txt and hit Enter

What this will do is create a text file on your desktop that includes all your configurations in regards to your network interfaces. Please copy the contents of that file and place them into your next message.

Also, please provide more information in regards to your setup.
1. Are you connecting wirelessly or with a cable?
2. Are other devices on the network connecting to the internet without issues?

Lastly, you have marked the thread as solved for some reason. Please undo this. If the issue is actually resolved, please share how you resolved it.

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.

I just got Cox cable and it hasn't been working right.

I have a netgear WG602 wireless access point. I can connect to it but it has limited or no connectivity. Repairing the connection doesn't work and doesn't give me an IP.

I connected the ethernet cable directly to my laptop and it didn't work at all. I called them and it worked by directly connecting, but the wireless still didn't work.

Then I messed with wireless settings to try to connect, and I finally got online but my ip is 70.x.x.x, the apparent IP for all Cox subscribers.

But I got that 70.x.x.x through my router instead of a 192.x.x.x so I have no idea why it's doing that. It's really weird and I still can't get a dynamic IP.

Thanks for the help.

Reference this thread:

Amazing Network Problem.

Router: D-Link d-524 V4000
Ethernet: Nforce via mobo Gigabyte GM-A570SLIv2

I am having similar problems as with the linked thread. What happened with me was I needed to download drivers for my 2nd pc because the wireless had issues. So I unplugged my Cat-5 cable from my main pc that was working and then plugged it into my 2nd pc. I downlaoded the drivers and then reconnected the cable back into the main pc. That's when the problems began. My 2nd pc is the exact same setup as my main other than the processor is different and it works great. Things I have done:

1. Connected straight to DSL modem.
2. Reset both modem/router
3. IPconfig shows the 169 IP.
4. Pinged the NIC with no loss of packets.
5. Reloaded the drivers via mobo CD(Vista x64)
6. Started in safe mode w/networking
7. Restarted DHCP Client
8. Verified configuration matched the other pc.
9. Reinstalled Iv4 using c:/windows/inf
10. Bought a PCI adapter in case the mobo connection was bad. Didn't work either.

I can't even access the router or modem on the main pc. I tried a static IP but will try what was suggested in the linked thread when I get home today. If you need snipits I can do that once I get home. I'll provide anything you need. Most of the snipits in the link thread have the same info as mine would that's why I linked it. Thanks in advance for the help.

I am running windows xp on a dell inspiron 4150 with a built in wireless card. My wireless was working fine until windows prompted me to reboot due to windows update. It stopped working after that. It is telling me that no ip address can be found and when I ipconfiged it with renew and all it still could not find it. It gave me an error message that says cannot connect to DHCP server.
Any help will be appreciated.
Thank you,
 

A:Network could not connect to DHCP server

Nothing really comes to mind, but if you're using Window's Wireless Zero Configuration maybe you need to reconfigure your wireless connection; especially if your network is protected with encryption.

I use the utilities from my wireless cards' manufacturers to connect to my WPA protectecd network and had no trouble today after the same reboot (two notebooks). Well, same reboot if you're talking about the critical update released yesterday.

Hi,
I'm working on a friends laptop & at first thought that she had this new Malware virus, but when I look at the IP config all of the IP addresses are zeros. DHCP is disabled for all adapters. When attempting to load IE page I get Error 105 - Unable to resolve the server's DNS address. I'm not sure where to start... Any help is appreciated!!

A:Can't connect to internet - IP's are all 0's & DHCP is not enabled

Try resetting her all her IP settings to default using the following IP reset file:-

Unzip the file, run the exe file and when asked to reboot, reboot.

If you ran the program it would be best to do a System Restore to just before it did its "fixes."

Disable encryption on the router and make sure MAC Address filtering is disabled and try to connect. If successful you can probably re-enable encryption and reconnect.

Do you have a non-Windows firewall with separate settings for wired and wireless?

Working on Win7 Pro x64 for years with same network settings - gigabit wired IPv4, fixed IP, fixed DNS, etc. Lot of other comps, network printers, APs - everything works fine. Suddenly last week my machine (only one) refused to connect - sometimes with yellow exclamation triangle on network icon, sometimes w/o it. But even if it tells "connected to internet" it does not connect to anything, even gateway. Few times it was resolved by reconnecting network cable. Trying various solutions without success. Then I noticed, that changing IP settings to DHCP solves problem - connection is back. Reverting to old fixed IP "disables" connection. I didn't install any new hardware or soft, only periodical software updates. Restoring system from "working" image made nothing. Have no idea - what's going on? Any way to fix or check what is a cause?

A:Can't connect with fixed IP, only DHCP works

As strange as it may sound, some Access Points (AP/router combo) will not allow devices with static IP addresses to connect* if the IP address of the device is outside of the DHCP range. They claim it is a security feature. The AP/router can tie the IP address to a MAC address - thus making it like a static IP assignment - but within the DHCP range. That IP won't be assigned to any other device.

*connect can mean different things. The computer is in the router's list of connected devices, but the computer is not allowed to connect to the internet or any local network assets.
I mention the above info so that I can ask if the firmware in the network device handling DHCP might have automatically updated and started enforcing that type of "security". Or, perhaps the DHCP range got changed and this one computer is now outside of the DHCP range.

Also, what happens if you assign the problematic computer a different static IP address?

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:

- 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.

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.

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."

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

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.

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.

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?

Same when i inserted to a different laptop it had no issues.

Things i have tried are:

* Disabling kaspersky Antivirus.
* Uninstalling the antivirus.
* Disabling all rules from Windows Firewall
* Uninstalled Virtual Box software to make sure other network stuff not creating problem
* Uninstalled and installed the driver several times
* Disabled and enabled the connecting several times
* Plugged out and in the cable several times
* DHCP and DNS client are running and set to automatic

But still it cannot make my laptop's LAN to get one IP from the DHCP server of the connection.

I cannot set a static IP as it has to work in DHCP.

Please help me out.

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

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.

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.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2)
Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
The Internet Browser in use, IE, Firefox, Opera, etc.


Please give an exact description of your problem symptoms, including the exact text of any error messages.


If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
