Similar problem on Acer 5810TZ (with AR928X), wireless was fine on 9.04, but on 9.10 it would disconnect after a few minutes and refuse to reconnect, giving the security password dialog. After suspend it would work for a few more minutes.
I installed the wireless backports and the connection works longer but then it won't work at all after standby. -- wireless atheros ath9k hangs after using 20min or later https://bugs.launchpad.net/bugs/452745 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
