Title:
  Wifi slow on Intel Corporation Centrino Ultimate-N 6300

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  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.
