Thread: Wifi (ath9k, 12.10) really slow, no solution found yet

hi all,

after couple of laptops using broadcom wifi picked out system without it. unfortunately, i'm in trouble again. it's not uncommon one, it's none of solutions i've seen far trick me.

problem: wireless internet connection extremely slow (averages <50k); pages on forum don't load half of time.

system: acer aspire s3 ultrabook, using ath9k driver.

now, i've tried solutions find past few days (a lot of came wild man), none of them worked. i've tried turning of hardware encryption trick (options ath9k nohwcrypt=1), added 8.8.8.8 etc. dns entries , have compiled , installed compat-wireless (3.6 stable)... until now, speeds stay extremely low.

symptoms slow overall speeds (<50k) , going down , again (stalling). moving closer ap seems short time, downloading speed drops again. speedtest.net shows same: speed starts out okay, keeps on dropping , dropping.

below output of commands give insight in current situation. sure hope (wild man?) willing help, working on brand new system not fun thing now. rebooting windows neither.

problem , (not working me) solutions found here: http://www.linlap.com/wiki/acer+aspire+s3

thanks,

jeroen
