I just installed Ubuntu 14.04 LTS. I am able to see the wifi but not able to connect to it. It keeps asking for my password again and again.
I am able to connect to my phones hotspot and and other USB wifi dongle such as MTS as well.
Other people who have recently installed ubuntu 14.04 while i did are able to connect to that particular wifi but not me.
I couldnot check to see if it works with other routers other than mine coz theres no other open network near by.
Friend of mine who is able to connect to the wifi has a sony e series I have a dell xps15 L502x.
