Description of problem: Starting with kernel 3.9 the module ath9k is not working properly. The connection through WiFi fails sometimes and can't authenticate anymore. Only a cold boot fixes the issue until it fails again. Version-Release number of selected component (if applicable): kernel-3.9.2-200.fc18.x86_64 kernel-3.9.4-200.fc18.x86_64 How reproducible: Random Steps to Reproduce: 1.Start Fedora with kernel 3.9 2.Connect to WiFi network using ath9k 3.Normal Internet and network access Actual results: When it looses the connection can't authenticate again, no matter what you do. Expected results: Stable connection as with kernel 3.8 Additional info: I experimented this issue with Fedora 16. It was fixed until kernel-3.8.11-200.fc18.x86_64 that is working fine.
