[arch-general] WLAN

[Christian Klaue]

Just a guess: with my Lenovo initially I had a similar problem which
turned out to be a missing driver. Installing some 3rd party AUR
package it worked fine. Have you checked lspci? Kernel mods? Which
module is built in? Ever searched for it? 

With my HP I am having some bios problems (caused by HP - I will never
get any HP anymore). After each reboot I have to wait for approx 3
minutes before it is working. Meanwhile wifi is constantly turned on
and off again: there is no hardware button but bios is still reporting
it had been turned off and on. Check if there are bios reports on the
net. Usually you are not the first. The same error does not appear on
windows. unassambling efi and compiling it again threw something like
30 errors on the wifi module in efi...
