Unstable Wifi

  • I'm using an old PC with LibreElec. I admittedly haven't turned it on in a while but I did the other day and saw:

    "[Failed] Failed to start Wait on network."

    When the system finished booting up I was not connected to wifi. I tried to connect manually but it seems to connect and disconnect intermittently. I increased the wait on network to 30 seconds but that didn't help. I updated to the latest beta version but that didn't help. I'm guessing there is a driver issue with my ac wifi dongle but the only error I see in dmesg is related to bluetooth. How do I troubleshoot this? Thanks!

  • Do you have auto update enabled? If so, it looks like your unit has automatically upgraded to the latest release. Your Edimax wifi is using a realtek chip which *might* be no longer supported.

    Because of the driver issues with realtek chips support has been limited and the preferred option is to use a Wifi bridge to ethernet.

    If you can remember the previous release, it might be possible to downgrade (Make a backup first)

    More Info

  • I looked back at my original attachment where I had run lsusb -v and found:

    Bus 001 Device 003: ID 7392:a811 Edimax Technology Co., Ltd

    Interestingly the verbose output also shows

    iManufacturer 1 Realtek

    iProduct 2 802.11n WLAN Adapter

    though this is an ac adaptor.

    Do you think its using the wrong driver and this is causing the problem?

  • Only 1 wifi (wlan0). I bet its a driver issue.

    "Your Edimax wifi is using a realtek chip which *might* be no longer supported."

    How do i confirm if my wifi adapter is supported and anyway to add support if it is not?

  • How do i confirm if my wifi adapter is supported and anyway to add support if it is not?

    A complete compatibility list does not exist (you have to watch LE's Linux kernel for that).

    When the product descriptions says Linux compatible, and it's not from Realtek, then give it a try.

    Here is an incomplete list for OpenELEC on RPi, just to give a small overview: RPi USB Wi-Fi Adapters

    Hint: An adapter with an antenna works better.

  • Hi, i have same problem on Libreelec for PI3 and PI4, on few boot the Wifi connection could work automatically or not. I use only the wifi on the PI. I thinks there is an unstable wifi connection protocol on libreelec. When i used OSMC on PI3 with a wifi configurated on wpa_supplicant, the wifi was worked everytime with not unstable behavior like that. But there is no wpa_supplicant possibility on librelec or i didn't find how.
