Windows Forum / Windows XP / Wireless Networking / July 2007Cannot acquire IP address
07/26/2007 02:27 AM I have a Linksys WAG54GS as Gateway for a small wireless network with a Dell Dimension 3.0 running XP with SP2. Also on the network are a wireless-enabled Brother MFC printer and a second Dell Dimension located some 30 feet from the access point; the first computer is very close. The setup worked satisfactorily for some time but crashed some weeks ago when I was trying to add another laptop. I reran the Setup from the CD for the WAG54GS and it seemed to complete satisfactorily. However when I try to connect I always get the problem "Cannot acquire an IP address". The access point(modem) functions satisfactorily with an Ethernet cable connection so I think it is programmed satisfactorily with the ISP. When I view Network Connections I see both the Ethernet Network (MSHOME) and the Wireless Network (WIHOME) showing "Connected" and indeed get a message saying "Connected to WIHOME _ Signal Strength Excellent". But if I disconnect the cable and try to use the wireless link it goes on endlessly trying to acquire an IP address. It worked very satisfactorily before with no cable, simply the wireless network. Both Networks are set with property "Acquire IP Address automatically". Can anyone tell me how to fix it ? I have not tried to connect the printer or the second computer until I get the first computer working satisfactorily. I sent a query to Linksys Support but it is hopeless. Ignores you query .

I have switched on and off a few times but that does not help - also rebooted the computer. "firmware" I have the CD which came with the router. I have been back to the web-site but do not see any update to the firmware on the disc, which did work fine until I got into trouble I followed the link you posted but it did not help although it seems other people have similar problems.

With some you hold down a small reset button with a paperclip or inkpen while you power cycle the device. With others you hold down the same reset button for a number of second with the device already running. Other brands may be different yet. > Unplug it from the electricity,...wait a few seconds,...plug it back in. > [quoted text clipped - 31 lines] >> How to Setup Windows, Network, VPN & Remote Access on >> http://www.HowToNetworking.com I said before that the router had no reset button but examining the back once more I found a red rimmed hole with reset round it in tiny type. Poked in there with a bent paper click and it seemed to reboot but ended up once more with "acquiring IP address" and finally said it could not do so and advised me to contact whoever manages the network - ME !

Check manually the Router DHCP table and make sure that it has enough range giving IPs. 2. Start with Wireless security Off and adjust it only after very thing works. 3. Give the Printer a static IP that is outside the DHCP range.

This is a very small network "Start with Wireless Security off" Again I don't think I know how to do this without running the setup program again. Will do this. I'm not bothered about the printer at this stage. I can always connect it with a long USB cable. I just want to get the computer on to the internet on the Wireless network at this stage. Thanks again. Stuart > Hi > 1. Check manually the Router DHCP table and make sure that it has enough [quoted text clipped - 3 lines] > 3.

This is a very small network Many of these box have a 50 machine limit on the number of addresses they give out. It may be adjustable, it may not be. That is only a limit on the number of DHCP Clients,...not the number of machine on the LAN. If you have less than 50 machines it is a moot point anyway. > "Start with Wireless Security off" > Again I don't think I know how to do this without running the setup > program again. Will do this. It means don't use WEP, WPA, WPA2 or whatever else the box offers. Security is probably off by default. If you didn't set it up yourself on purpose, then it is probably already off. When you sit at a Client machine and view the Available Wireless Networks List,..it will show your wireless network as being "Secured" or "Unsecured",...that is one way to know if it is on or not.

Most Linksys devices have a small button, usually on the back near where the power cord connects, that is used to reset the device. Typically, you press and hold the button for 10-20 seconds. This should be explained in the manual. On the other hand, resetting will likely also reset your ISP-specific information, so if you don't know how to set up that part of the modem/router, I would suggest not resetting. What "crashed" when you tried to add your new laptop, and what did you do to recover from the crash? It sounds to me as if your WAG54GS is setup with some wireless security (encryption) and that by running the "setup" CD, you've erased the password from your computer. If you don't know what that password is (did someone else setup your network for you), you'll have to reset/change the password on the router. If you don't know how to do that, you'll have to read the router's manual. I was quite surprised to find that Linksys does not have a manual for the WAG54GS available for download. I would at least expect there to be a manual on the CD that came with it. Most of the info you're looking for should be there. Rather than e-mail Linksys support, try their on-line chat support service, if it's still available. I've had good experience with that in the past (you can tell that the canned solution isn't applicable). If you can't get anywhere with Linksys, go to http://www.linksysinfo.org/index.php This is an on-line community of Linksys users, many of whom are quite knowledgeable. You should be able to get some help there. SignatureLem MS MVP -- Networking To the moon and back with 64 Kbits of RAM and 512 Kbits of ROM. http://en.wikipedia.org/wiki/Apollo_Guidance_Computer Lem Thanks for your helpful advice. I did try resetting but it continued to hang at "Acquiring IP address". If it removed the ISP information I can replace that and I have got the code for the WEP encryption. The WAAG54GS does not come with a manual only a skimpy Quick Installation leaflet and as far as I can see none on the CD. I have to stop now but will follow up your other suggestions tomorrow.

Seems to be a User's Guide on the Linksys UK site (although I don't know what "Annex A" means), and the manual says its for the "EU" version, but it's better than nothing (EU may only mean that the manual is in English, French, and German): http://www-uk.linksys.com/servlet/Satellite?childpagename=UK%2FLayout&packedargs =page%3D2%26cid%3D1129319214507%26c%3DL_Content_C1&pagename=Linksys%2FCommon%2FV isitorWrapper&SubmittedElement=Linksys%2FFormSubmit%2FProductDownloadSearch&sp_p rodsku=1123521940739 shorter version of above link: http://tinyurl.com/3dw4co If you can access your device's configuration utility (use an Ethernet connection; don't try to do it wirelessly), read Chapter 6 of the manual then get to the "Wireless" tab. Unless you've got an old laptop or an old wireless adapter, set the "Wireless Network Mode" to "G-only" (it will also work with the default, "Mixed"). Then click the "Wireless security tab" and set the mode to "Disable." Click "Save settings." Now try to connect wirelessly. If this works, then re-connect the Ethernet cable, re-access the router's config. system, and set the mode to WPA-Personal or WPA2-Personal. Which one you pick depends on the capability of your laptop's wireless adapter. WPA2 is better than WPA. Do not use WEP. > Lem > Thanks for your helpful advice.

SignatureLem MS MVP -- Networking To the moon and back with 64 Kbits of RAM and 512 Kbits of ROM. http://en.wikipedia.org/wiki/Apollo_Guidance_Computer Sorry to be so long in getting back. In the meantime I found the Manual was in fact on the CD and followed your instructions to read Chapter 6. Unfortunately the instructions for accessing the configuration utility are at the end of that chapter, rather than at the beginning ! So I reset and redid setup. That worked all right. I followed your instructions, turned off security. It worked. I got the message " You are now connected to WIHOME - Signal strength excellent" ! I was overjoyed until I tried to go on the net. Nothing doing. No connection. I couldn't get on the net and of course couldn't ask for help. I told you that I knew how to configure the connection to the ISP but alas I was wrong, or at least the Gateway utility asks for a little more information. I struggled with this a large part of Sunday and this morning contacted the ISP-Help-Line and found someone to walk me through the entries in the utility. At the end everything fine. The Network working on Wireless and Ethernet. Wonderful. After surfing just a little to check some sites, I realised that the Wireless Network was still open - no security, so following your advice, went back to the Gateway utility to change it. Unfortunately I forgot your instruction to reconnect the Ethernet connection before doing this. Result chaos. Both the Ethernet and Wireless Network became "Not connected" and "Repair" doesn't help. I finally realised that the problem was different security settings on the computer and the Gateway. Finally restored first the Ethernet, then the Wireless. I am back in business and eternally grateful to you for your time and patience. I still have to fix Security and note that you strongly recommend WAP-2 and not WEP, which I had before. I will read the information which I have very carefully and change the security settings on the computer first, then the Gateway. After that I will hopefully connect the other computer. The WindowsXP instructions advise you to us a flash drive, first in the existing computer, then the Access Point, then the new computer and then the first computer again. Problem is the Access Point (Gateway) doesn't have a USB port. I seemed to manage before and hopefully can again. Thanks again for your help and patience.

WPA2 is better than WPA. Do > not use WEP. Stuart, I'm glad to see that you are getting things sorted out. Windows Connect Now does assume that your router has a USB connection for a flash drive, and most do not. Apparently D-Link routers do. Here are some articles that you might find helpful. http://www.microsoft.com/windowsxp/using/networking/learnmore/bowman_05june13.mspx http://www.microsoft.com/windowsxp/using/networking/setup/connectnow.mspx http://www.microsoft.com/windowsxp/using/networking/setup/connectnow.mspx If you have already setup one computer and the router with the security you want, you can use Windows Connect Now to transfer all of the network settings, including the encryption key, from one computer to the other using a USB flash drive. What you can't do -- unless you have a router with a USB flash drive -- is setup the router itself. Note that you can use the Wizard to print out all of the settings, which you might want to do anyway, and keep the info in a safe, secure location. > Sorry to be so long in getting back.

SignatureLem MS MVP -- Networking To the moon and back with 64 Kbits of RAM and 512 Kbits of ROM. http://en.wikipedia.org/wiki/Apollo_Guidance_Computer Hi My personal recommendation is Not to use the Setup Disk (or use it as a coaster). Wireless by nature is not as stable and durable as wire, and sooner or later there is always some"Quirky" behavior. So it is worth while to spend one hour to learn the basic manual configuration of the Wireless Network, to avoid head aches now, and in the future. The Hardware's manual plus these pages can be a good tutorial. http://www.ezlan.net#Wireless Jack (MVP-Networking). > Thanks for your help BUT > [quoted text clipped - 21 lines] >> 3.

Unfortunately, I could not find how to access the Utility on the Gateway until later. (So easy - just http://196.182.1.1 with an Ethernet connection) Setup worked and I got the Network connected - Strength excellent. Problem was I couldn't access the net. I thought I knew how to connect to the ISP but didn't - or at least not in all details. The Help-Line of the ISP, solved that problem and my troubles are over - I think ! Thanks again.
