I ack the roaming by Seth. We have multiple 802.11n APs with the same SSID here that are WPA2 encrypted but on different channels. Those affected go into a roam loop. When they connect to a non-WPA2 single SSID AP they have no problem. I've seen this on three different Intel setups across multiple brands (so it's not "just a thinkpad thing").
It's also worth nothing that it is happening on several non-US laptops as well. We do have APs in use on channel 1, 6, and 11. To test Andy's theory we moved the 11s to 10. However the hotel's wireless has APs up to 13. The APs for reference are a mix of enGenius and Ruckus. In one test area I removed the enGenius and it actually caused more laptops to go into the roaming loop because there more APs of roughly the same signal strenth (as measured via wpa_gui) to choose from. I didn't save the wireshark capture but if you'd like to see that I'll do another one tomorrow if we have any affected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005832 Title: Intel wifi frequent disconnects To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1005832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
