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... ente On Sun, 2016-11-06 at 22:56 +0100, Silvio Siefke wrote: > Hello, > > i've installed Arch Linux today on Desktop (HP Elitebook 2540p) but > wifi work not.
