Public bug reported:

Hello,
On Intel Corporation Centrino Ultimate-N 6300 who use iwlwifi, the Wifi goes approximately (in my home) to 15MB/s in up and down on Windows 7, but it goes only to 5 - 6MB/s down, and 1 - 3MB/s up on Linux.

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.
