rtl8812au wifi dongle on RPi 3

  • The only USB devices attached appear to be an Apple keyboard and a mouse. I can't see any evidence of a USB wireless device.

  • Thanks,

    i'll dig a little deeper and see what I can find. Being able to ssh in and poke around is helping too. This is a very cool system, keep up the good work.

  • Hey all,


    I have a Tenda U12 dongle, rtl8812au chip


    Code
    1. [ 1540.658293] usb 1-1.1: new high-speed USB device number 3 using xhci_hcd
    2. [ 1540.749121] usb 1-1.1: New USB device found, idVendor=2604, idProduct=0012, bcdDevice= 0.00
    3. [ 1540.749140] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
    4. [ 1540.749157] usb 1-1.1: Product: 802.11n NIC
    5. [ 1540.749172] usb 1-1.1: Manufacturer: Realtek
    6. [ 1540.749187] usb 1-1.1: SerialNumber: 123456


    I thought 8812au should work out of the box, but unfortunately it does not for me.


    Tried


    Code
    1. LibreELEC:/sys/bus/usb # modprobe 8812au
    2. LibreELEC:/sys/bus/usb/drivers/8812au # echo 2604 0012 > new_id


    and still nothing, any ideas how to make it work with RPi4 running 9.2.0? Thanks

  • I have a TP-Link Archer T2U Nano which is a RTL8811AU and uses the RTL8821 driver (I added the ID and recompiled and it's working nicely).

  • I've added the TP-Link T2U Nano and some other RTL8821 devices - it should be included in the next LibreELEC 9.2.x release. Thanks.

  • Firstly, I'd like to thank all the LibreELEC staff (wherever and whenever you are or were) for all of the had work which has gone into this product. I've only just set up 9.2.1 on a Pi 3 Model B I had lying around and it's been fun. :)


    Like another poster in this thread, I also purchased an EDIMAX 7811UTC and realised it won't see any of my 5GHz SSIDs. Luckily I had one of these lying around from a work project and it works flawlessly - I watched Thor: Dark World at 1080p resolution for about an hour (needed to stop after that and get some work done, lol) with no buffering or stuttering. The TP-Link Archer T4Uv2 works really well also.


    Speaking of which, I have a feature request. As noted above, I was using one of the BrosTrend adapters for a work project and for that project I was using the gordboy 8812au driver which has LED control, while the driver in 9.2.1 appears not to. It would be nice to be able to switch the LED off, since it can be quite distracting (especially the bright green one on the TP-Link) and if I try hiding the Pi at the back of the TV, the signal reception suffers.


    Is there any chance of LED control being added in a future version? Many thanks.
