i am facing a lot of problems when i try to connect to internet over wifi in my asus x550lc laptop. In windows 8 the wifi works perfectly fine and its fast and stable. but when i use Ubuntu 14.04 ( i tried ubuntu 14.10 live booting also.. same problems), i found these issues -> Unstable wifi connection. The connection goes off if i use it for 5-10 minutes. in the middle of downloads etc -> Very slow internet & weak signal -> Wi-Fi password prompts appear on login screen.
i tried several solution found in online, like -> switch off the power management by Ubuntu for your wireless device -> resolve bug in the Debian Avahi daemon in Ubuntu
but the problem still exists. any idea how to resolve?
