Wifi does not come up automatically

    • New

    Howdy,

    I am totally new to libre.elec. I installed it on a raspi 4. Since my wifi key is really long I have enabled SSH on the box and setup wifi using this howto: https://www.jeffgeerling.com/blog/2023/conf…n-libreelec-ssh. In order to do this I put the box into my office, where I have an ethernet port available. Wifi works very nice then.

    But when I put the box back into the living room and connect it to the TV, then wifi doesn't work anymore, this message appears on the screen:

    No I could possibly enter the key, but this would be a tedius task. So, why doesn't it come up with the readily configured wifi? Or does Kodi have somehow a different wifi setup than the OS below?


    Many thanks in advance,

    Tom

    It's a long-running issue that impacts a small number of users. It is not RPi hardware specific. Things that may help:

    • Disabling fast-transition (FT) in access-point radio properties
    • Not using WPA3
    • Moving the device closer to the access-point to improve signal strength

    It is probably an issue with iwd (as reverting to wpa_supplicant works around it) but it remains unresolved largely because nobody who can replicate the issue has code-level fault finding skills, and nobody among project staff or regular technical contributors with such skills can replicate the problem.

    I managed to configure wifi via the libre.elec settings addon, which worked. Until now. I didn't change anything, it just says "invalid key". And now it's not working anymore, whatever I try.

    Signal quality can't be the issue, the router is just 3 meters away. I have even created a guest network with a simpler key just to make sure it is easy to enter in the settings dialog in time.

    I also connected the rasbpi with ethernet and tried to manually configure the wifi with iwd - this works:

    So, wifi in general works, the password is correct as well, it only doesn't work, when entered via the UI on the TV.

    Oh, but now that I re-read you comment, when I am working on the raspi via LAN, then I take it into my office. This is the same room where the wifi router is located. So maybe it's a distance issue after all?

    That's just a shot in the dark: Do you have some kind of special characters in your passphrase? Or maybe only a 'Y' <-> 'Z' issue from the difference between German (GUI) vs. English keyboard setting?

    The issue has nothing to do with passphrase characters and it's definitely influenced by signal strength. The error message shown is probably the result of an error handling failure in iwd code. Instead of correctly catching the error and failing gracefully with a meaningful message you end up falling-through to a unintended wrong point in code and seeing "invalid key" instead.
