I am having a very puzzling problem on my eeepc:
wifi was working just fine, when suddenly (maybe after plugging in a SD card in the built-in slot) boom, no more connection. Typing iwconfig in a terminal, reveals no wireless interfaces. What the heck happened to wlan0???
The ath9k module is not loaded, rebooting does not help, neither does modprobe. lspci in a terminal shows the ethernetcard, but no other network cards. It's as if the thing suddenly evaporated.
What can I do to trouble-shoot?
