I've tried the kernel from comment #17 but I'm still having the issue (connection unusably slow and most often 'dies' after a short while... but still appearing the be connected from NetworkManager's perspective - requests just sit there waiting) - I've also tried the .39 kernels from the PPA in comment #8 (and of course the normal Natty kernel).
This is on an Acer Aspire 5742G; lspci reports the wireless chipset as "03:00.0 Network controller: Atheros Communications Inc. AR9287 Wireless Network Adapter (PCI-Express) (rev 01)". I also tried the workaround described in comments #1 and #6 with all three aforementioned kernel versions and this also appeared to have no effect. If there's any logs/reports that'd be helpful for me to provide, please let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761176 Title: wlan (AR928X, ath9k) slow since upgrade to natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
