[RPi5] IP address suddenly blank

    I booted up the Rpi5 today which was running the latest 0927 build and noticed all of the sudden that I had no WiFi connection at all. Everything was blank. I decided to downgrade all the way down the 0923 but even then, that didn't work. My router does show that the last time the Pi was active was on Sept 27th, so it definitely wasn't the build on the 23rd. I even tried each build after. I changed absolutely nothing in settings either. Just booted, and found that I have no WiFi. Thought I would update to the latest Sept 28th build through the USB drive, and that didn't fix it either. Here is what I show on the Pi under network settings. Then here is what the actual connections show. Signal quality at 100% as well as and IP address shown.

    I did also check on my router app to make sure that the Pi was not paused for some reason, and it was not.

    Any thoughts? I was thinking some WiFi adapter update on a build, but not sure. If so, even downgrading didn't fix it.

    So I left the Pi on overnight, and just rebooted, and the first picture in the screenshot under "state" now actually says online instead of ready. Booted the latest Sep 28th nightly, and it appears to be fine as well.

    Not sure what caused the issue, but it appears after leaving the Pi on all night, it somehow reconnected. I guess so far the issue resolved itself.

    So update. Came home, booted the Pi, and no internet again. The wireless "state" says ready again instead of online. Tried to refresh, but nothing. Even did a disconnect and then reconnect under its settings, and nothing.

    You provide a description of the problem, but with little useful data. Could be useful to know how your RPi connecting to the wifi: IP is DHCP or manual set; Wifi router encryption does WPA2, WPA3 or mixed mode?
    For stable connection for now you should set the RPi to fixed IP, in the router encryption only WPA2 (use strong password), don't use in the router any MAC based IP assignment.

    Code
    echo "options brcmfmac feature_disable=0x2000000" > /storage/.config/modprobe.d/brcmfmac.conf

    If you run that ^ over SSH and then reboot, does this restore previous behaviour?

    This should functionally effect a revert of https://github.com/LibreELEC/LibreELEC.tv/pull/11785 which is a direct feature/capability change for the wireless stack that would have rolled out in RPi5 nightlies around September 19/20.

    HiassofT FYI


    I haven't tested that yet, but what I did find out really by error, was when I tried to connect to my guest network, it said invalid key, then went straight back to trying to connect to my main network, and it connected and went to online state.

    I was able to then download the latest Sept 30th nightly, use filezilla to update since it hasn't shown yet in the Pi, rebooted, no internet again. Went to connection settings in the Pi again and the "state" shows ready for wireless. Scrolled down to the guest network, tried to log in as it says idle. Hit connect, typed in passphrase. Says invalid key. So then the Pi goes right back to trying to connect to the main WiFi network, and suddenly it does. I am online. Obviously a temporary workaround, but this workaround seems to work each time I try it.
