RTL8821AU (AC600 Plus) on Mango?


I have updated my Mango to the latest “snapshot 3.211” and Im trying to use a “RTL8821AU” USB wifi.

dmesg give me just:

[ 650.630176] usb 1-1: new high-speed USB device number 3 using ehci-platform

Nothing else.

Any ideas? Thanks!

The driver may not be installed on your router.
Try installing the “kmod-8812au” package which may work for RTL8821AU.

While 8812 “ct” kmod on the vanilla latest openwrt seems to be working, on the mango does nothing.

Any ideas?

You can try rolling back to the previous firmware release.

Also, log into SSH, run the following commands and post the results:


lsusb -t

cat /etc/config/wireless

Otherwise, wait for GL.iNet to respond.

I do not know of the 8812 “ct” package. Did you try the 8812au package?

yes I installed and removed both. none of the “8812” did the trick.
Ill check lsusb

It looks like your TP-Link wifi adapter is detected, but it does not have a driver because “Driver=”. If there is a driver, it should show something like “Driver=XXXXXXX”. You have to try a wifi adapter that has a supported driver package.

It seems the Netgear AC1200 A6210 works on Mango with MediaTek chipset:


Note type on the URL: A6210, not A6120


Unfortunately this device is not for outdoor use nor does it have an external antenna.
Still hoping GL would work on the request for more options. Preferrably dual band of course.
