I have tried whatever I could find on forums but couldn't get wifi connected.
Here is the list of what i have tried.
Added "blacklist sony_laptop" to /etc/modprobe.d/blacklist.conf
Also tried http://www.emmolution.org/?p=253
Also installed latest version (188.8.131.52)from here. http://wireless.kernel.org/en/users/Download/stable/#Recommended
It detects all the wifi's but wont connect. I can connect to my Binatone router using my android phone and mac air but not from Ubuntu. It was working fine till yesterday. But my laptop shut off after battery discharge and since then its not connecting. Please help me here. One is not supposed to waste a day trying connecting to wifi.
Thanks a lot.
