Thanks Jesse, I'm afraid there's no wifi switch in BIOS. Actually, BIOS options related to LAN/WLAN are as follows: LAN powersaving: disable Embedded WLAN Device Radio: enable Network Interface Controller(LAN): enable LAN/WLAN Switching: enable Wake on LAN: enable I tried to toggle these options except the first one enabled/disabled, but still no luck. Any suggestions? On Wed, 22 Feb 2012 17:42:50 +0200, Jesse Jaara wrote: > Your BIOS migt contain a wifi swich.... > > Sent from my phone. Sorry for any spelling mistakes >
