I have an Aspire 8930G and the light on my wireless LAN keeps going out meaning I can't get the internet wirelessly. Switching the wireless LAN button makes no difference. If I plug in a cable it works fine so I know the router is ok. Only a system restore to a couple of days ago helps and then after the couple of days further use the problem starts again. Anyone got any ideas?

Gosh, this worked! Thank you. Vista. I uninstalled the Intel 5100 then reinstalled it. At first PC moaned with a Windows error 31, but this cleared itself when I went into device drivers section of Control Panel>System. This showed the question mark error by the Network Adapter, wireless Intel 5100 ... but then magically it created another one (which it called Intel(R) Wireless WiFi Link 5100 #2). At this point, when I pressed the Acer WiFi switch on the 8950g right hand side, it now blinked orange. So this was now working.

There was still the device driver Intel(R) Wireless WiFi Link 5100 (not #2) showing, which had the error, but I simply uninstalled this.

Thanks again, hope this helps others. Gosh, this worked! Thank you. Vista. I uninstalled the Intel 5100 then reinstalled it.
