Thread: kernel 5.5.xxx not working with wireless

  1. #1

    Cool kernel 5.5.xxx not working with wireless

    I am running Tumbleweed on an HP laptop. I ran "zypper dup" for edition 02072020 and my NetworkManager could not find my wireless adapter and, hence, my networks. The only thing it saw was Bluetooth. Fighting off panic, I downloaded the latest Tumbleweed install image on another computer with the intention of updating the problem away but when the install tried to find a network adapter, it could not. I have since done zypper dup daily and noticed that the kernel is being updated with disturbing regularity But nothing after 5.4.xxx will find the wireless doo hickey. In fact, the last two versions of 5,5,xx will not even load on my machine! I have to boot with 5.4.xxx to get online.

    I am just curious and will try zypper dup on a few of my machines just to see what shakes out vis-a-vis wireless connectivity.

    Since I have a workaround, I do not consider this critical but I am curious what broke and when it will be fixed. I have not dissected the boot logs, yet, but like I said, I can make the machine work so it is a low priority for me, just a pain in the butt!!!

    Now, I ain't no LINUX guru but it seems to me that the iwlwifi driver is blowing up...

    Default Re: kernel 5.5.xxx not working with wireless

    This upstream bug report suggests that this problem may have been patched already in kernel 5.5.3.

    https://bugzilla.kernel.org/show_bug.cgi?id=206333

    Suggests that if you can live with your workaround, you should be seeing this kernel pushed to you automatically within a few weeks.
