A kernel update came through the Ubuntu Update Manager today which has fixed the problem. I am now running, according to 'uname -a'
$ uname -a Linux NeurosLINK 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:07:17 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux The System Monitor reports the kernel as 2.6.38-10-generic. It reported my previous kernel as 2.6.38-8-generic which I reported as 2.6.38.8 in comment #22. That kernel definitely did not fix the problem. The changes in the 2.6.38-10 kernel include fixes to (something like) the wireless compatibility module. I am happy to report that I can now ping my router without packet loss and one test with speedtest.net gave a result of 45Mbps, the closest I have ever got to my ISP's advertised 50Mbps, though the average speed is around 32 Mbps. I want to say a big thank you to the people who fixed this bug and enabled my HTPC to work properly again. -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/761176/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
