Hello, can anybody help?


My desktop was recently having some noise issues, so I took it into a shop. As part of his inspection, the guy took out a small board which has the socket for the monitor plug, and this board also has a small fan on it.

When I got the PC set up at home again, it no longer could find our wireless network (which it has for a 6 months before!). I type this now, using our wireless on another computer.

I used the Microsoft Help tutorials on my PC, but it was a dead end. For example, it said "Open 'Network Connections'. Click the wireless connection icon, and then, under 'Network Tasks', click 'View available wireless networks'. " Well, there was no wireless connection icon, and no 'View available wireless networks' in my Network Tasks.

The PC is Windows XP, SP2. My WiFi sensor thingy (?) is an antenna, with a long wire that screws onto the back of the CPU tower.

Thanks a lot for any advice!

Have you checked to see if the wireless card is firmly plugged into the motherboard? It may have gotten jarred loose during the repair. Be sure to unplug the system from the wall and to ground yourself on the metal chassis before reaching inside of the case.

Once that's done, boot into Windows. Go to Start...Run...and type in "devmgmt.msc" (without the quotes) and press Enter. Look for the Network Adapters and see if your wireless card is listed there. If it is, does it have a red X or yellow ! by it?

Next, go to Control Panel and click on Network Connections. Is your wireless connection shown there? What does it say about the connection there? Right click on it, and select Properties to see more details about the connection (in particular, check the properties of the TCP/IP - it should (most likely) be set on "automatic".

Do you have security setup on your wireless router? If so, have you entered the appropriate key to allow access?

Finally, open up your browser, select Tools, then Internet Options, then the Connection Tab, then the LAN settings button. Check to see if the proxy server is enabled. If it is, remove the check from the box and click OK

Let us know if any of this helps - if not there's more stuff to try.

Good luck!

Duh! Thanks! Yes, the wifi card was a bit loose. I followed your first step, and problem solved. Thanks a lot!
