    Wifi always worked before the update, one of which was kernel-firmware-iwlwifi. Now when trying to connect, the window says "Configuring interface" for a while, then "The WiFi network could not be found" and "Connection 'howardcathy2.4G' deactivated." If I try to connect five or so times, sometimes it finally will. This morning it has not connected to wifi. It's on a cable now.

    Regarding firmware, I get:
    Code:
    howard@X201-oS15KDE:~> sudo dmesg | grep firmware

    Wifi always works correctly when this system is booted to Windows 10. What is happening here, and how can I fix it?

    Default Re: Wifi connection problem after update

    Based on the MAC address this is an Intel Wifi card.

    Regarding the firmware: I would be good to know if these failures are also seen before the update of 8 Sep.
    You should be able to find that in the journal, with something like "sudo journalctl -b 7 | grep firmware" you can check the boot log 7 boot ago.

    If there you do not see these failures I am pretty sure it has something to do with these failures.

    You'll have to take my word that there were no connection failures prior to the updates.

    I deleted kernel-firmware-all and kernel-firmware-iwlwifi, then reinstalled them and rebooted. Wifi is connecting most of the time now. May be tolerable if it holds.

    Default AW: Wifi connection problem after update

    The only thing I see is:
    kernel-firmware and a new kernel.

    Can you boot with the previous kernel and see?

    If that do not help, can you install the previous kernel-firmware packages and see?

    Booting to the previous kernel made no difference. It had the updated kernel-firmware-iwlwifi - 20220509-150400.4.8.1. Seems the update put the new firmware in both the latest (running) kernel and the previous one.

    Running the previous kernel (5.14.21-150400.24.11-default), I installed the previous firmware (kernel-firmware-iwlwifi - 20220509-150400.4.5.1) and rebooted, again to the previous kernel, but no change. The latest kernel is now booted, and it too has the previous firmware (kernel-firmware-iwlwifi - 20220509-150400.4.5.1) but still has connection trouble.

    I just did, but now cannot connect with NetworkManager. That is what I have always used. I just switched to wicked, and it connected. Our building has a wifi network and NetworkManager has trouble connecting to it. Strange.

    For the first time, in many years, my spouse's laptop has had very intermittent connection to house WiFi. As my machine is on Ethernet I cannot reproduce this. in last few days, effectively she connects and the machine logs off of WiFi itself while she is browsing or sending emails. Random disconnects at a few minutes or longer. Has anyone else since say 24th Sept 2022 had intermittent connection to WiFi. System uses Intel WiFi with internal laptop aerials at about 20 metres through two brick walls.
    Any suggestions from you folk?
    PS Her machine uses openSUSE LEAP 15.4 up to date with KDE desktop on Intel hardware.
    Could it be hardware problems?
    Regards
