I had Ubuntu 12.04 previously installed on my Laptop and i was having problems in connecting to internet (I was connecting to Wifi), and Chrome and Firefox both showed "Connection to Server lost", and when i tried updating through terminal it was also not able to connect to internet, but my bittorrent client was connecting fine to Wifi internet connection. So i installed Ubuntu 14.04 alongside Windows 7 and i'm having same problem in it also.
Also if i try disconnecting to Wifi and connect again, internet works fine for 5-10 minutes but then again it starts giving error. Also, there is no problem in internet connection as it is working fine with my Android Device and Windows 7.
