Does "Fix Committed" mean that I shouldn't be seeing this? 'Cause I do, this on Feisty with 2.6.20-16-generic. Large file tranfers over wifi break, confusing the wifi setup. Interestingly enough, resetting the access point allows me to restore things (by rerunning iwconfig/dhclient on the client). However, I've seen this happen on several different access points now, from three different vendors (Apple, Billion, and D-link). Less intensive use (web browsing) cause no problems, it seems.
It may be related to encryption, I've only tested this with WEP (both short and long keys). Reducing the bandwidth to 2Mbit seems to alleviate the problem a bit, but I'm unable to make the setting "stick", it gets reset to max at regular intervals. After the network is broken, I noticed that I couldn't make my wifi card associate with the AP, repeated iwconfigs would mostly display "not associated", and only occasionally the AP MAC address - which would then disappear at the next invocation. dhclient would broadcast, but never get any replies. This is on a Core 2 Duo Dell 620m. I haven't tested the maxcpus option to see if the problem is related to SMP. -- WLAN disconnects repeatedly from AP when using WPA on a SMP machine https://bugs.launchpad.net/bugs/56894 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
