>From http://www.intel.com/content/www/us/en/support/network-and-i-o /wireless-networking/000005511.html, one can conclude that this issue will probably never be fixed. The Ultimate-N 6300 is only supported for kernel 2.6.30. Obviously, it would be great for someone at Intel to confirm this. The driver persists in newer kernels, but if anybody is going to work on it to fix any problem remains to be seen.

Before Ubuntu 11.04 → It was slow. After Ubuntu 11.04 → It was slow. On Ubuntu 11.04 (Only for test): The down speed is approximately 11MB/s and the up speed is approximately: 6 - 8MB/s The driver contain a regression for speed performance. Currently I use Ubuntu 14.04 LTS with Linux 3.18.1 (Vivid package) but the speed is already slow. The range of the card is reduced, and I take sometimes 2 - 5min to discover a network. Connection/disconnection to an other network can make a bug were the fastest way to change network is to disable/enable the card (if it works), or reboot the computer. It make this card absolutely not reliable because of the driver on Linux. --- ApportVersion: 2.14.1-0ubuntu3.11 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: valentin 4266 F.... pulseaudio /dev/snd/controlC0: valentin 4266 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2014-11-24 (245 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: Dell Inc.
