my wife's Toshiba Satellite L500-1WG won't connect to wireless networks suddenly. In fact, it appears not to have a wireless network driver any more. I tried downloading the latest driver and updated the BIOS, but to no avail. Anyone have any idea what could cause this and what I can do about it?
In the Toshiba PC Diagnosis tool, under network it just shows:
RealTek PCIe FE Family Controller version=7.3.522.2009
But no reference to a WLAN controller.
Edit: Never managed to find a solution to this, so I ended up putting in a new USB wifi dongle. Working fine now, but still a mystery. My best guess is that the built-in wifi adaptor broke somehow.
