Might be a dupe/same as the issue in 702722 You can check current upstream drivers to see if problem is fixed there http://people.redhat.com/sgruszka/compact_wireless.html I'm having a similar problem with this adapter. I get frequent packet loss, and frequent absurdly-high ping times (probably also packet loss with automatic retransmit, I guess). The same machine sees no packet loss when running Windows and seemed to be working fine before I upgraded from F13 to F15. Other devices on the same network work fine. The AP is about three metres from the F15 box, in the same room. I have updated to 2.6.40-4, I've tried Stanislaw's latest compat-wireless and compat-wireless-next packages with their respective kernels, and I even downloaded the compat-wireless source (August 8) from here: http://wireless.kernel.org/download/compat-wireless-2.6/ and built it. I also tried nohwcrypt=1. Nothing makes any difference. Any suggestions on what to try next? If bug is on current upstream driver send bug report to ath9k-devel.org and cc linux-wireless.org. Note in email this is regression. You probably will be asked about providing more info, i.e dmesg with debug= module option. Brandon, do these performance problems continue with 2.6.40 kernels? |
