No it was a fresh install, and because of a bad amd driver I need to re- installl this 5 times, so be sure my report is about a fresh install, today I have always the problem, and I have not changed anything between the basic installation. (Just install the daily updates)

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.
