I have now tested RC5 and RC6 as well. The TCP stuck connections seems to be gone but the wifi connectivity issues still remain. I travelled this week and out of four or five networks or so I connected to none of them worked properly. The connections stay up most of the time but I get extremely poor performance, dmesg fills with "[ 1396.363645] iwlwifi 0000:44:00.0: fail to flush all tx fifo queues" messages. It seems like something actually happens to the routers themself which over time reduces performance and causes the connection to completely stall, as the performance issues are persistent across reconnects and computer reboots. IE I connect to a network, it works for a time but then slows over the course of minutes and eventually I cease to be able to connect to it at all. Reconnecting doesn't work. Reloading the module and rebooting the machine also is ineffective. I suspect that rebooting the router would reset the situation and allow it to work again for a while, but I can't confirm as these networks are all public networks where I don't have access to the router.
Also since they are were not my networks, I'm not sure what model/brand the wifi routers were. Everything still works fine with my home wireless. It is very erratic between different networks. I also went back and tested the newest 3.2.0-31 kernel (latest stable 12.04 as of this writing). The issue was unchanged since 3.2.0-29 and -30, with "Queue 2 stuck for 2000 ms." messages appearing and the connection grinding to a halt after a minute or so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1039205 Title: 8086:4238 iwlwifi lost connections and poor performance with mixed networks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1039205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
