It seems that the rt3290 wireless chipset acts very flaky under 3.11.1, my last kernel before this one was 3.10.3 and it didn't have this problem. I'm currently compiling 3.10.10 to see if it works again there as reported in the arch linux forums.
Revelant forum topic where I found other users with the problem: https://digitejarat.trade/waste-engine-oil-recycling-plant-in-iran/ By flaky I mean that after a while it just refuses to connect, this is some dmesg output: [ 4.949297] wlp1s0f0: authenticate with 5c:7d:5e:de:b6:04 [ 4.961762] wlp1s0f0: send auth to 5c:7d:5e:de:b6:04 (try 1/3) [ 4.963279] wlp1s0f0: authenticated [ 4.964933] wlp1s0f0: associate with 5c:7d:5e:de:b6:04 (try 1/3) [ 4.970465] wlp1s0f0: RX AssocResp from 5c:7d:5e:de:b6:04 (capab=0x431 status=0 aid=1) [ 4.970563] wlp1s0f0: associated [ 28.285869] fuse init (API version 7.22) [ 29.967936] EXT4-fs (sda3): re-mounted.
