I am unable to connect to the internet with Ubuntu 12.04.3. The Windows 8.1 partition however can access my WiFi perfectly. From what I've managed to gather my adapter is not being assigned an IPv4 address and cannot ping the router. Running dhclient did not work. Curiously I am able to connect and search with google through the WiFi however no other websites work. A wired connection seems to work the majority if the time.
Details: Adapter: Intel Wireless-N 7260
OS: Ubuntu 12.04.3 w/ kernel 3.12.2
nm-tool output: https://gist.github.com/bloxgate/7715106
dmesg output: http://paste.ubuntu.com/6502541/
