First AP deauthenticate us for reason 2 (WLAN_REASON_PREV_AUTH_NOT_VALID), then we are unable to connect to with AP - getting timeouts waiting for response for various request from AP. At first glance this looks as some AP malfunction, but I can not exclude bug in iwlwifi driver code or in mac80211 linux stack. Try to update AP firmware and use swcrypto=1 module option, does any of that helps? Any info on above swcrypto=1 and AP firmware? |
Created attachment 477597 [details] dmesg output when the connection is lost Description of problem: On two Lenovo laptops with KDE spins of F14 (x86_64) the wireless connection is dropping randomly, perhaps once or twice a day. When the connection drops, it's not restored automatically, but NetworkManager asks for the WPA key (propably a feature of NM). The connection might drop during a file transfer or also during no significant network activity. I don't see a pattern. This happens on a multitude of networks (tested on three, 802.11g with WPA2-PSK). The bug is happening on 2.6.35.10-74.fc14.x86_64 #1 SMP kernel, but has also been a problem on the previous versions The wireless cards on the laptops are Intel Corporation PRO/Wireless 5100 AGN [Shiloh] and Intel Corporation Centrino Advanced-N 6200 (rev 35) AGN. In the attachment I have added dmesg output.
