Description of problem: After updating the kernel on my laptop with F15 wifi (Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express)) connects all right, but after a few minutes it disconnects and starts to connect once again, failing. Moving back to the old 2.6.42.7 kernel solves the problem. My connection is with WPA2. Haven't checked without encryption. Version-Release number of selected component (if applicable): kernel-2.6.42.9-1.fc15 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: lspci -vv for my atheros wifi chip 04:00.0 Network controller: Atheros Communications Inc.

Please attach the output of 'dmesg' after the problem starts...thanks!
Just after I get disconnected these lines are added to dmesg.

Also, the issue is not related to WPA. Same thing happened with an open wifi router (connection with no authentification or encryption.)
Kernel 2.6.42.12-1 seems to work OK. Don't know what changed, but everything is allright.
