Description of problem: Compared to Fedora 14, the wireless takes several seconds more to connect on boot and wake from sleep(going from less than 5 in F14 to 20-30 seconds in F15). Once the wireless connection is actually made, the network performance is greatly degraded(a 20MB download took 5 minutes compared to the previous 5 seconds on F14). The slowdown can be counteracted by adding "hwcrypt=1" to the ath9k options. Version-Release number of selected component (if applicable): 2.6.38.4-20.fc15.x86_64 How reproducible: Every time wifi networking is needed on a computer with a AR928X wireless NIC. Steps to Reproduce: 1. Install Fedora 15 Beta on computer with AR928X wireless adapter 2. connect to wireless network 3. try to do anything with the network. Actual results: Wireless connection takes in excess of 20 seconds to connect. Once you actually try to do anything, the network connectivity is excessively slow to the point of uselessness Expected results: Wireless connection should be made in roughly 5 seconds and speed should be comparable to Fedora 14 and Windows.

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?
