The symptoms and logs are the same. Btw, if it matters in some way, my WiFi connection is a N-band only. *** This bug has been marked as a duplicate of bug 785239 *** |
Created attachment 558135 [details] /var/log/messages Description of problem: After an update to the 3.2.2-1.fc16 kernel, the wireless connection became pretty much unusable. It would keep working for a few minutes, after which, even though technically active, every attempt to go to any address would time out. Even to the router (192.168.1.1). Disconnecting and reconnecting from NM would bring it back up, but again, only for a very short period of time. /var/log/messages is not that useful. The last line when connectivity is lost is: iwlwifi 0000:04:00.0: Tx aggregation enabled on ra = c0:3f:0e:2d:f8:f0 tid = 0 I am attaching the full log of that boot session, it comprises of one disconnect/reconnect attempt and then connecting with wired network. Version-Release number of selected component (if applicable): 3.2.2-1.fc16 How reproducible: every time Steps to Reproduce: 1. Obtain a machine with the said wlan card 2. Connect 3. Wait a few minutes Actual results: Connection stays up but nothing gets through Expected results: Connection is working as expected Additional info: Please let me know how I could obtain more useful logs
