I installed Ubuntu 14.04 alongside Windows 10 but the wifi hasn't worked once since installation. However, it works fine in Windows.
I made sure that on Windows the wifi is turned on. And I've already tried this solution Wifi problems with rtl8723be in Ubuntu 14.04.
When I go to System Settings->Network and try to turn the Wireless ON it immediately turns OFF and doesn't show any wifi networks.
The wireless info is here: http://paste.ubuntu.com/13347247/
