[Kernel-packages] [Bug 1618782] Re: wifi stops functioning briefly after connecting to network
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system start: - always needs a re-connection to WiFi After wake-up: - always works # Further steps I've noticed bios-outdated-2.65 flag added to the bug.
