Unable to view available networks

Until a week ago I was able to view available networks using Microsoft WZC.  Now WZC claims that “there are no wireless networks available.”

I have done the following:

      1.      Reset the stack (netsh int ip reset c:\resetlog.txt)
      2.      Manually started WZC
      3.      Replaced the wireless card
      4.      Reset Windows using “restore point.”
      5.      Tried almost every “fix” available from a Google search.
      6.      Followed the procedure provided by the Microsoft site.
      7.      Tried with the firewall on and off.

The system is a Toshiba Satellite Laptop, Windows XP Pro w/ SP3.

I have also tried a USB wireless NIC.  When using it’s viewing utility I am able to view all AP’s in the area.

Any help that will point me towards a solution would be appreciated.

Is there a hardware switch on the laptop for wireless?

Regardless check in the bios to see what it says regarding wireless, particularly around control, set it to software control only (if possible).

When you are having these problems, what is the state of the Wireless Zero Config service in services.msc?

Thank you for the quick responses.

I did a "Repair Install" on the OS, and except for having to re-load all of the security and SP's it made no difference.

Yes, there is a hardware switch, and I have tried to view the network with it on, and with it of (needless to say the NIC does not work when the switch is off).  With the switch on, I can see the NIC in the "Network Connections" window.

I have not checked the state of WZC using "services.msc", I simply open the services display window to verify that WZC is in the "Started" state.  If it will make a difference, I will recheck using "services.msc."

The card will be dependent on 1 or 2 cables running from it to the screen and up the sides for it's antenna, any chance there has been a disconnect or some damage there?

Also, what does the wireless key on the keyboard (not the switch) do right now if anything? And as I said previously if there are any bios settings experiment with them.

The auxiliary and main antenna cables are in place, and do not have any apparent physical damage (no fraying, connectors snap into place).

The BIOS does not provide any control for the wireless NIC.

The function (FN) key for the wireless does not seem to effect the NIC in any way.

Thank all who commented, but I think that the problem is in the OS (it is windows after all).  I am going to wipe the drive and do a fresh install.  This appraoch is what windows usually needs to repair the OS.  Thanks again.

Try an Ubuntu Live disk before you do anything brash.  You can boot to it from the CD and see if your wireless works OK.  If it does, then you know it's Windows and not the hardware.

The issue has been resolved with a "fresh" install of the OS!

Thanks to all who replied, it was informative but not helpful.

Input from experts was not helpful in resolving the problem.  All save one were directions to repeate what I had already done, and did not resolve the issue.
