Laptop network adapters seem to disappear

[CalvinHobbes]

I have a laptop with Vista Sp2. Recently was unable to connect to a network or the internet. I can see wireless networks in range but can't connect to any. Wired connection doesn't work either.

After restoring back to a previous restore point the network adapters both worked fine for about 20 minutes and then stopped working.

While they were working I could use IPCONFIG to see information from both adapters. After they stop working IPCONFIG returns nothing for these two adapters as if they're no longer in the system. Device manager shows them installed, enabled and no errors.

Never seen anything like this before. Any thoughts or ideas?

I have not seen that on vista but I had seen a similar situation on xp where the machine was infected with spy/malware.

you could also try the following to reset the network settings from a command prompt

netsh int ip reset c: \windows\iprst.log (no space between : and \ i had to put a space as it puts a frowny face)
and
netsh winsock reset

then do a reboot and see if its working better. If not download Malwarebyte and/or Superantispyware and see if it finds anything

Check the computer for Viruses and Lamware and clean it up if needed.

Then do WinSock and TCP/IP Refresh.

Type Cmd in the Start Search text box.

Press Ctrl-Shift-Enter keyboard shortcut to run a Command Prompt as an Administrator. Allow elevation.

Type netsh winsock reset in the Command Prompt , and then press the Enter key.

Do the same processes for refreshing the TCP/IP just replace the typed command with.

netsh int ip reset press Enter

ipconfig /flushdns press Enter

Restart your Computer.

I have scanned the system for malware both inside and outside of Windows. Nothing showed up. I have also run the commands listed in both posts above and that had no effect on the issue.
