Here is a bug that is affecting thousands, if not more, of users. https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/630748
Wireless drivers for Linux seem to be dysfunctional, particularly iwlagn. Is Intel aware of this or planning a fix yet? It has been reported for almost two months now and I would really love to have a fully functional wireless device as soon as possible. Thank you.

This is the best way to get support for Linux on your Intel wireless adapter. When I have questions or customers ask me for assistance that is where I go for help.
