hi i'm having a wifi issue, i have win7 and ElementaryOs (ubuntu 14.04) on my toshiba satellite c55-c5206s with a broadcom BCM943142Y and the wifi randomly disconnects, it doesnt happen while im in windows. Linux is updated.
what i found, broadcom drivers are a little broken, and when wifi signal drop down from 55% the wireless constantly disconnects.
help please, i really want to start using linux full time
