Thread: Edup dongle and rtl8812au issues

    Question Edup dongle and rtl8812au issues

    My wireless USB dongle is unable to connect to any Access Points: https://deviwiki.com/wiki/EDUP_EP-AC1607 The connection simply hangs indefinitely or repeatedly requests a password (dmesg below). It works perfectly on Windows and through searching, it seems the drivers for this device work perfectly for everyone else using linux. Is anyone able to help troubleshoot this issue?

    I'm using the driver rtl8812AU_8821AU-kmp-default-20200719_k5.10.16_1-14.8 from the Sauerland repository but have also tried openSUSE's other drivers rtl8812au-5.9.3.2+git20201214.b95e750-1.4 and rtl8812au-kmp-default-5.9.3.2+git20201214.b95e750_k5.10.16_1-1.4 with no difference in results.

    When attempting to connect to a router:
    Code:

    Using a my mobile phone's wifi hotspot, I'm repeatedly asked for a password until after a several tries KDE informs me that the interface is disconnected due to "No secrets provided" I made the password very simple for testing purposes and am also able to connect to the same hotspot using my laptop's internal wifi interface:

    Update: I was mistaken regarding the default openSUSE drivers rtl8812au-5.9.3.2+git20201214.b95e750-1.4 and rtl8812au-kmp-default-5.9.3.2+git20201214.b95e750_k5.10.16_1-1.4. They actually do not load by default and are recognised as "8812au" by lsmod after forcefully loading with
    Code:
    insmod /lib/modules/5.10.16-1-default/updates/8812au.ko
    Code:
    # dmesg
    [  152.141115] usbcore: registered new interface driver rtl8812au 
    [  170.258463] usb 2-2: new high-speed USB device number 7 using xhci_hcd

    This is confusing since the default openSUSE and Sauerland drivers use the same upstream but only Sauerland's driver registers my wireless device after insertion. Again, any advice for troubleshooting would be most welcomed. I don't need a USB wireless device for my laptop, but I do need for this device to function on my desktop.

    Do you only set WPA and not WPA/WEP in your Routers configuration?

    Yes, it is WPA only.

    I can not reproduce this because of missing hardware.

    There are many reports with this bug, but no solution.

    8811AU or 8811CU chip, not 8812AU. Check which you have.
    Possibly you need Realtek RTL8811CU/RTL8821CU USB Wi-Fi adapter driver for Linux.
    Or try to compile driver from manufacturer.

    It's very confusing that the various Realtek 88XX drivers on GitHub support many chipsets, but rarely specify exactly which are not supported. My chipset is indeed RTL8811AU and most RTL8812AU/21AU drivers should support it.

    UPDATE: I've had partial success compiling https://github.com/aircrack-ng/rtl8812au (v5.6.4.2) and installing the driver via DKMS. The device only works with 2.4GHz and isn't dual-band. There are many, many forks so hopefully I'll eventually find a project which will also allow me to use 5GHz with my device.

    I'm new to openSUSE, so what would be the best way of suggesting the project switch to the aircrack-ng drivers for upstream? A four year old Realtek wireless device that's still in production and being sold should work out of the box without the need to learn about Driver Update Disks.

    Sorry, I somehow missed the comment. It would seem the only viable solution for me is to create a GitHub account and create an issue with https://github.com/gordboy/rtl8812au-5.9.3.2

    No:
    Realtek 8812AU 8821AU Wireless LAN Drivers

    https://github.com/abperiasamy/rtl8812AU_8821AU_linux

    This package contains the rtl8812AU_8821AU linux kernel driver for AC1200 (801.11ac) Wireless Dual-Band USB Adapters.

    The module will be called "rtl8812au.ko".
    See:
    https://build.opensuse.org/package/s...l8812AU_8821AU


    I applied a kernel 5.10 patch to https://github.com/gordboy/rtl8812au-5.6.4.2, but oddly that version of the driver didn't recognise my device.
    That is outdated:
    README.md
    rtl8812au
    Realtek 8812AU driver version 5.6.4.2 ** NOW OBSOLETE **

    Please use 5.9.3.2 version at https://github.com/gordboy/rtl8812au-5.9.3.2

    Sorry, I somehow missed the comment. It would seem the only viable solution for me is to create a GitHub account and create an issue with https://github.com/gordboy/rtl8812au-5.9.3.2
    Thats only the rtl8812au driver, your ID is not inside:
