[Bug 1618782] Re: wifi stops functioning briefly after connecting to network
Kgorbi: 1) To keep this relevant to upstream, one would want to continually check for, and test the latest mainline kernel (now 4.8.1) as it is released. Could you please advise? 2) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1618782 Title: wifi stops functioning briefly after connecting to network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1618782/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry for the delay but I have finally got time to perform more tests. # Testing with other devices I've observed, that switching to other WiFi hot-spot makes a difference: the problem is only observed, when "Lenovo W530" (Ubuntu) connects to "Speedport W 724v typ A". When testing with another hot-spot device or when testing hot-spot with another device, everything works flawlessly. Hence, it looks like some kind of compatibility issue. # Testing Ubuntu Kernel-4.4.0 After system start: - always works After wake-up: - rarely works - sometimes re-connecting to WiFi suffices - more often WLAN PM must be disabled # Testing mainline Kernel-4.8.1 After system start: - always needs a re-connection to WiFi After wake-up: - always works # Further steps I've noticed bios-outdated-2.65 flag added to the bug. I'd like to update BIOS and see, if this could be solved that way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1618782 Title: wifi stops functioning briefly after connecting to network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1618782/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Michael H Wilson, if the WORKAROUND doesn't help you, then you have a different problem that this report is not scoped to. Hence, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal: ubuntu-bug linux Please feel free to subscribe me to it.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
