I noticed the same problem with ath9k on an AR9280 rev.2 chipset. I tried compat-wireless for 2.6.38 but that didn't helped much (fixed dma errors and chip lockup issues, but speeds were still bad).
Using today's compat-wireless snapshot (compat-wireless-2011-03-20) seems to restore normal traffic speeds, Hurrah. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/735171 Title: driver ath9k is too slow or not responding -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
