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.
