Denis, i had same problem with the low speed and low signal power on 3.6.11 and Ubuntu 12.04. And after i executed "ifconfig wlan0 down" and then "ifconfig wlan0 up" - network manager started showing a message "device not ready" and i didn't know how to fix it.
After days of reinstalling OS I just give up and installed fresh 12.04 + manually compiled the driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049466 Title: Need support of Ralink RT3290 wifi support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1049466/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
