Alienware 17 running 14.04.2 can't connect via Ethernet or Wifi

I recently installed Ubuntu 14.04.2 on my Alienware 17 laptop, and haven't been able to connect
to the internet through wifi or wired connection.

I was able to find out the make of the Ethernet and Network Controllers.

Ethernet Controller: Qualcomm Atheros Killer E2200 Gigabit Ethernet Controller (rev 10)
Network Controller: Qualcomm Atheros Device 003e (rev 20)

This is my result after running the command " lspci -n | egrep '0200|0280' | awk '{print$3}' "
