Okay I am having a completely infuriating issue with my wireless on my laptop. Let me outline the issue.
I have a thinkpad with an atheros wifi card. Here is what lspci tells me about it
02:00.0 Network controller: Atheros Communications Inc. AR5418 Wireless Network Adapter [AR5008E 802.11(a)bgn] (PCI-Express) (rev 01)
I have an extremely irritating problem of it randomly de-authorizing from networks. (as you can see in the dmesg output link below, line #1076)
It happens most frequently on 5ghz N connections but will happen on 2.4ghz connections as well. it seems completely random, and when it deauths, you cannot reconnect until you rmmod the ath9k module and reload it, or physically turn off the power to the card and turn it back on again. Sometimes, but not all, killing wpa_supplicant will fix it, albeit temporarily. If i open up wavemon, i can watch the link quality and signal strength fluctuate wildly ALL OVER the map, from zero to 100%. It does this extremely quickly and with great frequency whenever traffic is being sent or recieved over the card.
Now for the fun part, this problem has persisted through upwards of 5 different kernels, and a ‘zypper dup’ from 12.2 to 12.3. I have tried everything i can think of, and every tweak and config setting i’ve seen come up on google. nothing helps. I am at a complete loss. From what i could find, i am lead to believe that it could possibly be a bug in the atheros drivers. Another thing to note is that it may only take place when i am connected to a wpa2 secured access point, but i am not 100% sure on this point.
If any more information is necessary, just ask and i’ll gladly oblige.
