have experienced exactly the same problem, with the same chip and the same kubuntu version as above. Same laptop with 9.10 runs just fine. Running with almost no load runs fine too, even for a long time. As soon as for example ktorrent gets started, the issue occurs within a few seconds. So seems to be more of an throughput issue, which doesn't allow the timeout to be acknowledged within the given 500ms.
according to syslog the "No probe response from AP <mac-address> after 500ms, disconnecting." messages comes from the kernel. Could it possibly be some real time issue, some change of timeout parameters, or different scheduling / priorities due to the new kernel, and / or all this new graphics stuff? just an idea, don't know too much about Linux interiors, but have been fighting many years with the real time OS QNX4, and came across similar situations there. Are there any timing parameters regarding this error, which can be modified, or which have been changed to this new kubuntu version? -- Broadcom 4318 wireless connection drops frequently https://bugs.launchpad.net/bugs/648331 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
