Hi have this exact problem with a Toshiba NB200 Netbook on Ubuntu 11.04 (64 bit) which has the Atheros AR9825 WiFi.
It basically works perfectly within 1-2 meters of the wireless hub but going into another room or a different floor renders the WiFi connection useless. It should be noted that it works perfectly find using exactly the same hardware on WinXP. So far, I have tried both the linux-backports-modules-net-natty-generic package and also compiling and installing the latest compat-wireless but to no avail. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773154 Title: Atheros AR9285 extremely slow & unstable on 11.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
