hi Nitram

indeed, it seems like an OS issue.

things i could think of:

1. Check the last program/ setting/ windows update that might have changed your wireless network configuration.

2. A system restore to the date before the problems occurred is hopefully going to be effective

3. While this is unusual, maybe check that the builtin wireless lan adapter is enabled in the BIOS

4. Check that the WLAN auto config service is not disabled.

Click the Windows Start button
Control Panel --> Administrative Tools --> Services


My desktop is running Windows 7, but it does not have a wireless card. The default setting of the service is set to Manual.

Ive yet to check the default settings on a machine with a wireless card, but do check on yours to see that it is not set to Disabled
