[RPi4] WiFi Issue

    • New

    Dear all, I was struggling today with this issue, while I was trying to use my rpi4/libreelec with a portable hotspot on my phone. In addition to the issue, when trying to join the network, I had a suspiciously small number of wifi networks detected.

    The problem disappeared as soon as I changed hdmi port on my TV. Initially I was using the (e)ARC port. Could be that the audio return capability triggers a bug?

    Anyway I hope that someone finds the above helpful.

    No, but it might trigger a PSU issue. We have to see a log to be sure...

    Please provide a full debug log.

    How to post a log (wiki)

    1. Enable debugging in Settings>System Settings>Logging
    2. Restart Kodi
    3. Replicate the problem
    4. Generate a log URL (do not post/upload logs to the forum)

    use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

    Hi, the RPi's built in tiny wifi antenna is notoriously weak. Maybe it's some kind of the EM field of the HDMI cable what could make interferences. What you can try it, change the HDMI cable with one with better quality and EM shilding, and if you have a USB-Wifi dongle, you should try it too, usually works far better than the built in.
