Home computer not reconizing Network?

Hello! I have one Dell Desktop that runs Windows Vista and has a wireless PCI card. I also have my work laptop (also a Dell) that runs Windows 98 and has an internal wireless card.

I have a 2 wire AT&T router/modem from AT&T that works most of the time but every month or so it just stops working and I have to call AT&T (usually a waste of time because they always say it is my equipment that is not working).

In any case, my DSL recently went down for 10 hours and when I got it working again; my network stopped working.

I have been able to get my work laptop to recognize my network and is working wirelessly. However, my home desktop for some reason is not recognizing my network so I can only connect via an Ethernet Cable. I checked and it shows my PCI adapter is working properly.

When I try to connect wirelessly it says 'unable to connect'. Then I ask for it to 'repair' but that never works.

On the 2wire router/modem all lights are GREEN (working). The Power light is solid green, teh Broadband Link is solid green and the local network light is solid green making it seem as if all is working fine. I think in my trying to fix on my own, I may have changed a setting or something incorrectly causing the issue. However, I am a novice and I'm not clear what I may have done or how to fix it.

Any help is greatly appreciated.
Thanks in advance!

Hello again ilovesharpei :) I'm sorry for the delay -- are you still experiencing this issue? If you are, please try the following steps.

Before trying the following steps, disconnect the Ethernet cable and then attempt to connect via wireless. Once it fails, post an ipconfig /all.
  • Select Start
  • In the Start Search field type cmd -- right-click on the cmd program and choose Run as administrator
  • In the new command prompt window, type ipconfig /all > C:\ipconfig.txt
  • Navigate to your C: drive and open the text file ipconfig.txt -- please copy/paste the contents of this file into your next response.
Along with this, look in your event log for errors/warnings that occur around the time that you attempted to connect to the wireless.

Step 2 - Event Log/Viewer errors/warnings:
  • Select Start
  • In the Start Search field type eventvwr and press the ENTER key
  • In the new window, expand Windows Logs and then select System -- this will display a list of all system events. Look for any errors and/or warnings (denoted by a red 'x' or a yellow '!'). If you find any, please post the relevant heading, along with the details inside by double clicking on the error/warning, and then copy/pasting the information from within.
    *Note: You'll mainly be looking for DHCP and TCP/IP errors/warnings -- however any and all errors may be relevant.
What type of security do you have setup on your network (i.e. WEP, WPA)?

Suddenly, my network deceided to work again. No idea how this happened. I started following your directions by removing the ethernet cable and after doing that it just found the network this time. I find it quite strange when it would not work for 2 days and now it's working. I guess I'll count my blessings for now. If I have more problems later I will come back to the forum.

Thanks so much for your time; I appreciate it!
