I can confirm this happening on a Dell Latitude E6500 with the following wifi: 0c:00.0 Network controller: Intel Corporation WiFi Link 5100
I'm seeing the same messages, and am getting extreme latency spikes (>8000ms within the local network) as well as packet loss > 60%. The proposed workaround helps - the connection throughput is much slower than it should be, but at least it is stable with acceptable latency and no packet loss. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762007 Title: iwlagn: Received BA when not expected -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
