Wireless Network - DHCP - Help

Q: Wireless Network - DHCP - Help

Dear All,

Iím having some problems with my Wireless network.
Iím struggling to get my wireless devices to connect to my wireless network. The only way I can seem to do it, is by assigning them an IP address manually Ė otherwise they get given a 169.xxx.xxx.xxx number.
Ideally, I want the devises to get the IP address automatically.

Look at the diagram to see my network.

Itís not a secure network Ė I havenít given the Wireless Router any Mac Addresses. I live in a very remote area, so Iím not bothered about security until I have it all working.

The wireless Router has 4 Earthnet Ports and 1 ĎInternetí Port.

My ADSL Router has all my Internet settings
(Both are Netgear)

My question is: How do I get my Wireless devices to collect automatic IP addresses?

Hope you can help.

I am really suck with my network. I live in a shared house and the landlord seems to have no idea so I'm having to take control, though as you'll quickly notice I dont have much clue either.

We have a Virgin internet router downstairs, provided by thembut the wireless signal hardly passes the room, so there is a cat 5e cable through the wall, upstairs to a router that I have installed DD-WRT on, that we then intend everyone to connect to wirelessly, though some are wired.

I have put the cable from the Virgin box into the Linksys normal bit (not the one that you usually put the internet one in), but I have no idea what to do now. I've tried searching but all I can find is if I was picking up the internet wirelessly, but it its wired. A few things seem to mention DHCP though.

Any help would be amazing please. If you dont have time to write how, or point me in the right direction, then just the name of what I'm trying to do would be much appreciated, but any help would be great.

Thanks a lot,

So I have a small business I do IT work for. They are using Engenius WAPs for wireless which support multiple SSIDs and VLAN. DHCP is handed out by a Win2K8R2 server.

Now they want to set up a guest wireless network that only has access to internet and none of their internal resources. Problem is they need connectivity to the DHCP server. They have all dumb switches that don't support VLAN tagging.

I haven't worked much with VLANs, but I understand the concept and I'm trying to figure out if there is a way to provide what they wish (which is pretty straightfoward) without either

a. having to change the WAPs for something that have built in DHCP (that can be enabled on a per SSID basis) or
b. replace the dumb switches with switches that support VLANs

Any advice greatly appreciated. Thanks!

Hello, I have been experiencing some problems on my home network. I have problems with AOL, FTP and steam online games like counterstrike, team fortress 2, and day of defeat. I get these problems about 3/4 of the time, and 1/4 these programs will work.

When I sign into AOL I get a message saying "Could not connect to authentication server:
Windows socket error #10060". On FTP about half of the time I am not able to connect, and I the connection keeps timing out. On the steam games, when I open up the game dialog, I don't get the auto-retry option that is normally available. I tested these problems on other computers at my house and the same behavior occurs.

In my LAN, there is a domain controller which also acts as a DNS server and DHCP server.

And only thing that I need is wi-fi. I have a good router. What do I do with that?

If I set it up and disable DHCP on that, it gets an ip But all the devices in my network have 10.0.0.x

How do I fix it?

A:I have my DHCP and DNS. I need wireless.

Enter the web setup of the router and change its local IP to something else in your range. Disable DHCP in it and point everyone to use your server instead. You may need to use the IP once for changing this parameter, then use whatever IP you put in it.

I am adding a wireless router to my network, and I don't know if I am supposed to enable or disable the wireless DHCP?

My network accesses the network through a DSL modem. Attached to the modem is my router, which acts as the network's DHCP server. There are about 50 computers connected to it, all wired.

But now I'm adding a wireless router to a part of the network. In the configuration page of the wireless router I can enable/disable it's LAN DHCP server and enable/disable it's WLAN DHCP server. I know that the LAN DHCP server should be disabled, because I already have a DHCP server on the LAN. But do I need to enable the WLAN DHCP server to get wireless to work?

I ask because, to play it safe, I disabled the wireless DHCP server. But my wireless computer, when it connects, fails to get a dynamic IP address.

Thank you for looking.

A:Should wireless DHCP be enabled?

Read other 13 answers

I was trying to help some friends locate a problem on the wireless system they use. They said it uses a sonicwall dhcp server, and access points to assign dynamic IP to the public.

Using ipconfig /all it lists the right DHCP server and gateway, but the incorrect DNS servers for their network. one of them is which we googled and found mention of W32.Tidserv.G at http://www.symantec.com/security_response/writeup.jsp?docid=2009-032211-2952-99&tabid=2

So that might be the cause...
The problem now isn't simply to remove an infection, but how to locate the actual computer which most likely would be a laptop of one of the frequent public visitors.

Also what would be the best way to identify the infection quickly on a computer if we did manually check each.

One a few rare occasions due to interference or power outages my wireless broadband connection from my ISP will go down. As a result my Mandrake 10 firewall it will loose it's DHCP address and I will have to manually down and re-up the eth0 to get connected again.

What I would like to do is to run a cron statement that will test to see if I have an active connection to my ISP's gateway (doing like a ping request) and if not then asume that the connection has failed and have it down & re-up the eth0 port automatically. Maybe this script should then sleep for 30 seconds and re-test for an active connection, if active then exit otherwise repeat the process again.

I'm having problems figuring out a good way to test for an active connection. Does anyone know of a good script command(s) I can use to ping the gateway for the test part of this script?

I suspect that the problem is somewhere between your ISP and the antenna on your roof. If the antenna is directional maybe it rotated a slight bit, or blows in the wind, or a tree limb sometime blows into the line-of-sight between you and the ISP. Or maybe the ISP just has issues.

I think you should discuss this with your ISP, but also be on the lookout for patterns, such as

I have a wired client server network, and I want to implement wireless access. Currently, the network is a mess. The network consists of a single server and multiple hubs setup around the building that then connect to the ports in each room, the typical setup. Wireless setup has been attempted by placing wireless routers throughout the building, but by no means have they been properly configured. The routers' DHCP servers have been left on and are now creating problems because they are trying to assign IP's to the wired connection. I assume by turning off the routers' DHCP server that the server should take over, but then it appears that the wireless computers can't establish an IP. The routers being used are mostly Linksys, and there are a few D-Link. Is it okay to use a normal home network router? What is the correct way to configure the router so that it merely broadcast a wireless signal and doesn't conflict with the DHCP server? Would access points make more sense? If you haven't deduced yet, I am not in charge of the network I am just the one looked to to find the problem. The person who is in charge knows very little besides what they have learned in a few classes and they are hardly ever around. I myself know only basic networking. That meaning not much more than what you learn for A+ certification and from home and small network experience. Any help or suggestions that could set me on the right track would be much appreciated.

Hi all

Got another Vista wireless networking problem.

Running Vista Business and connecting to a 3Com Officeconnect wireless router - this is set as a DHCP server with a pool of 5 addresses - MAC address filtering and WEP are enabled.
We also have another DHCP server on the same subnet (not a great idea I know but the boss's decision unfortunately)

When I connect to the 3Com, although it connects successfully, it uses the other DHCP server to assign a valid IP but doesn't assign DNS settings. Both can assign these ok, tested with XP.

I would have thought that this was the other DHCP answering before the router if it assigned the full details but it doesn't assign the DNS or gateway.
I tried using the TIDs from MS to adjust the broadcast flag to see if it was an issue with the type of router but makes no difference. Have also tried other KB articles and changed the values for the DHCP in the registry (changes back to the incorrect one once connected)

Things I've tried with no success:

Recreate the connection
Manually assigning an IP etc works ok
Disabled MAC filtering and encryption - same results.
Disabled IPv6
Changed Broadcast flag
Manually edited details in registry
Release/renew/flush ipconfig
Searched here and other places for solutions and tried most....

One more bizarre thing that happened is that this same problem was affecting 2 laptops running Vista - one of them picked up valid info from the 3Com and has stuck with it - even after the lea... Read more

Once I got the laptop, I wanted to, of course, have it available to access my dial-up connection (so I could be in other rooms within the house and still access the internet on the amazingly slow speeds of dial-up since it's the only thing available here). Basically after a while, I decided to switch the ICS over to my newly purchased Linksys Wireless G PCI card and setup an ad-hoc network...that worked too, but the only problem was that the "client" desktop could no longer access the internet through the Windows XP Gateway since you can't bridge ICS (at least I've never been able to get it to be a success). So, I setup AnalogX's Proxy program and configured the computer to work as such. But, that gets old after a while when you're limited to certain ports, etc...so, I went out and bought a D-Link DI-524 Wireless Router so I could have both my connections going to the same ethernet port on my computer so ICS would work.

A:Netgear ProSafe DHCP / Wireless Issue

Read other 6 answers

I am replacing a defective Netgear router that was working in this same configuration for years. I am replacing it with a TrendNet TEW-731BR (N300 WiFi Router). This router will be used without WAN connection at all - just purely as a wireless AP with the intent that it passes everything through the LAN port to the "parent/master/A" router which has DHCP activated and has access to the internet.

Quick summary:
Master - (DHCP is to
New TrendNet - (DHCP disabled)

My configuration is a straightforward LAN-to-LAN, same-network type of cascade:
(start disconnected from everything - just connect via wifi to the TrendNet router)
* factory reset the TrendNet router
* Go to the setup page and...
** disable DHCP
** set the static IP address to an unused IP address outside the DHCP range of the master
** change admin password

The computer I was using for configuration now works great. Full internet access, able to ping/access anything on my intranet, etc.

Any other device hangs on access and ultimately says it couldn't get an IP address. If I set up a static IP address then I can connect with the other devices.

It's as if the TrendNet router doesn't know to hand the DHCP request over the LAN port.

I'm getting really annoyed with this boot delay I'm having. Ever since I installed my linksys wireless card, at windows boot there is about a minute delay after the GUI comes up, and then finally the wireless adapter utility loads in the systray, along with antivirus and other things.
I thought maybe a new card would help, so I got a different brand and have the exact same problem. I expect windowsxp is being dumb and trying to contact a DHCP, before it even loads the necessary wireless utility for connecting wirelessly. Can anyone recommend a solution?

A:XP slow boot with wireless card, DHCP?

It is likely searching for a IP address . . I leave my card out of the notebook unless I am connecting to a wireless network . . starts much faster. If I need it later, I insert it and let it find a network.

I have had a network for almost two years with no problems, and for some reason my laptop has not been able to get online for about a week. It did this once before last year sometime, and I phoned Bellsouth; they said to shut down all the computers and then restart them, and that fixed the problem. It did not help this time.
I have tried everything I can think of.

My laptop is a Sony Viao with Windows 2000. I am using a Linksys router and wireless card with my Bellsouth Westell DSL modem. Someone else set up the network for me, but I don't have contact with that person any more to help me. I will probably phone Bellsouth again, but thought I'd try this, too. I tried Linksys' live chat but they kept getting disconnected.

When I type in ipconfig /release it says it's already released. When I type in ipconfig /renew it hangs a long time and then tells me that the DHCP server is unreachable.

I have three computers. One is this Dell I am currently typing on, with XP, and it is connected directly (wired) and works fine. Sometimes the connection goes out and I have to unplug the modem and plug it in again and then it works fine. That has always been true, though.

I have another Dell, an old one with Windows 98, and it is wireless. We don't use that one very much because it's slow, but it has a wireless connection and sometimes it can't get online, either. It has troubles but sometimes it works, sometimes it doesn't. That's been for ab... Read more

Good Evening,

I'm having a problem with my laptop. I recently removed some spyware and now when i reboot, i have to manually start the wireless zero configuration & DHCP Client service manually. These are some of the things i've tried to fix the problem:

1.Made sure i didn't have another wireless device that's trying to manage my wireless connections.
2.Went into the network connection properties & under the wireless networks tab, made sure the "use windows to configure my wireless network settings
3. went into windows services and made sure DHCP Client & Wireless zero were set to start automatically (& started)

After i reboot, i have to manually start it all over again. I've been all over the net trying to find answers and suggestions & nothing seems to work. Any help would be greatly appreciated. I'm using Windows XP SP3.

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.

I have 3 network cards in my Windows 8.1 computer.   Each is attached to a different network.   I have assigned a static IP address to network card 1 which is on the internal LAN segment.   I want the other 2 network cards,
which are on different networks to run in promiscuous mode (IE.  No IP Assigned) so that I can sniff traffic.   There are no DHCP servers on those 2 other networks but there is one on the LAN which card #1 is plugged into.

My problem is that the 2 other network cards are getting IP addresses from the DHCP server on the card #1 network.   How is that possible?   If I disconnect card 1 from the network, the other 2 cards don't get an IP address.  
If I connect card #1 again, the other 2 cards get a DHCP assigned address.   So how to I stop network card #1 from forwarding DHCP traffic to cards #2 and #3?   Anyone know?

The Server went down - it is at shop for repairs. Meanwhile everyone can acecss internet fine - router is the DHCP and DNS server. However today one computer on the network is getting an APIPA address and can't ping the default gateway or any other computers on the network.

Anyone have any idea what to try next? All other computers on the network are accessing the internet just fine.

Hello Everyone,

We our setting up a Training Company to assist unemployed IT people in the Silicon Valley area of California. Our group is very small and having a hard time even getting our network here started. Here is the problem: We have Windows 2003 Server Enterprise 180-day usage disc (from a book we bought to learn). We have 5 static IP addresses leased from DSL carrier. They are for example: thru with a gateway of [these are only IP numbers used for example to prevent hacking] my subnet mask is We tried and tried for 2 weeks now and still can not get the complete network to work. We need: Step1.) The server to be secure with a firewall (but willing to forgo that and add later) Step2.) the server to issue Ip addresses from a pool of thru 12 to 3 workstations running XP(we decided to make the server, subnet mask is and gateway Step3.) Have access to the internet on all workstations and the server too. All we have succeeded to do is get the dhcp to issue out addressses to the workstations and even that i think we got lucky. We think the problem is somewhere you need to tell the (maybe iprouting?) setup that the Public ip address is the and gateway, subnet info and to route to the server PRIVATE ip address

I am having a problem with an NVDIA network connection. The network is MB based 750i chipset.
After the latest batch of updates certain sites will not display certain objects. I have found the easiest test site is YouTube where the video previews are blank and the initial flash eventually pops up Connection Reset By Server. Google and other sites without this kind of information work fine. Also the Pandora Gadget does not work.

If I allow the adapter to use DHCP I have the problem, if I manually set the IP with the exact same information the connection works fine. I have pulled drivers out, updated everything, reinstalled drivers... used netsh int ip reset and netsh winsock reset. I'm not running anything except the windows firewall - that I know of.

I had this problem in Vista x64; but after going through everything eventually it started working. I originally though it was caused by VitrualBoxes Bridging adapter. I could actually get it working check the Bridging Adapter and cause it to behave exactly like this. However, unchecking it did not always fix it, it sometimes required reinstalling the drivers.

My x32 installation (this is a dual boot machine) doesn't have VirtualBox installed. I'm guessing it's something behind the scenes in the bindings; but I'm at a loss.

Any help would be appreciated.


A:NVDIA Network Problem only when using DHCP

Hi sulldawg,

Welcome to Vista Forums!

Although it sounds like you did some of this, please go to and follow the instructions in: Network Posting Tips. Even those parts you already did (at least some of them), do so again using the batch file to make sure it includes everything (and it can't hurt to do it again).

When creating the IPCONFIG /ALL screenshots, please do so both with and without using DHCP so we can see how they differ when it is and isn't working (you may need to include multiple images to capture everything and please be sure to label the files so we know which ones apply to which circumstance).

Thank you and good luck!

I have this problem with a computer i'm trying to fix for my dad. This computer is used at his job, and its exposed to _a lot_ of dust. (not sure if this has anything to do with it, but there's a possibility)(also, the cooling rib for what i believe is the graphic processor was badly installed, and fell off as i opened the cabinet. I have put it back on with heat-carrying paste, and i still have a normal image on the screen, so i think it works...)

A bit about the specs, as far as i can remember them:

2 GHz Intel Pentium IV
512 MB RAM
AOpen motherboard
Sound, network and screen cards are on the motherboard
Running Windows XP Home

So all and all, a decent computer. This computer did have some spyware when i started looking at it, but it should be taken care of, as i bought Norton Internet Security 2006 and ran a full scan (i did not get to upgrade the definitions, reason for that will follow).

Before i installed it, i had arranged it so that the wireless network and internet worked on the computer. When i got back the day after, to install the Norton package, i noticed a lot of spyware, and took care of it. The computer was acting really slow for its specs, but after cleaning up a bit it works better. Now here is the problem: After i installed Norton Internet Security, the internet & network stopped working! Here's what i know:

Both the connection for LAN and WLAN contains protocols for Netware and IPX (even the new WLAN card that i bought did).... Read more

I saw something relating to rogue DHCP virus earlier in this forum however I do not believe it is what we are experiencing.

On Friday our company got hit with a redirect which appeared to be from W3.org, but spoofed. It was then stating to "update" your browser for incompatibility. It is an unknown as to whether or not (:P) anyone actually "clicked" on the update, but since then a "phantom" DHCP server comes up every so often upon various PC's at this point I know it is traveling around.

After quick diagnosis we determined that something was "creating" a DHCP server on our XP PC's. A redirection then sent the PC to a network out of Eastern Europe. This effectively was starting to swarm across the network and replacing DHCP settings.

It is a rootkit and I am using Combofix to remove it, I am aware of the dangers of using Combofix having used it for nearly 10 years now. I would rather take the risk of damaging a PC than my network. I just have not had time to review the logs and see much info. Even if I did, we all know what the answer is to that.

My question is does anyone know what this is and how to stop it? It has popped up several times since and believe it may be floating around somewhere within the network, but what to look for and if possible how to prevent the future outbreak, I am shooting from the hip currently playing whack-a-mole.

So in the end I am looking for what is this rootkit named and also looking f... Read more

A:Rogue DHCP virus in the network


Without seeing any logs it is impossible to diagnose this infection.

It sound like this is a fair sized company and I think the best option is going to be to contact you IT department/support and have them remove the infection.

We are here to assist the home users who fall fail to infection, I am afraid it is not really our place to take over from your paid/onsite IT support.

All the time these machines are networked, you will be chasing your tail trying to remove this.

Your IT department should be able to clean the network in next to no time.

im having trouble connecting to my freinds belkin router across the street when using my new Dlink AP.
When using my laptop in a cirtain position i can connect and it recieves a ip from router okay.
Problem is i want to pick this signal up using this the Access point and boost it around my house.
When i log into the access point it shows that the router is connected to my access point okay so far. Problem is that it does not ever get an ip from the dhcp server. the router across the road has dhcp enabled and like i said earlier, the laptop gets an ip okay and connects to the net ..

My access point is a DLINK DWL 700p 802b and the remote router is a newer 802g..
I have MY AP configured in repeater mode using the routers mac. I dont know if i would be better off using accesss point mode or client mode because i dont know what there for..

So basically when using ap, laptops stuck on aquireing ip.... any help would be great...

DHCP is something you need to enable on the router/modem. The computer can only be set to obtain ip via dhcp, see here.
