RTL8812au problem in 20.04

[rpessoa]

That's your device:We wonder then, why the driver loads and doesn't create an interface and trigger Network Manager and get to work.

Let's look for clues in the log:


sudo modprobe 8812au && dmesg | grep -i rtl

Hello,

I was using my Ubuntu 20.04 with no issues. Yesterday I did an update and my wifi is down. I followed what you posted here:


modinfo 8812au | grep 003F


alias: usb:v13B1p003Fd*dc*dsc*dp*ic*isc*ip*in*

But the next step gives me an error message:


sudo modprobe 8812au && dmesg | grep -i rtl


modprobe: ERROR: could not insert '8812au': Exec format error

Any idea what I can do next to fix my wifi that was working before the update?

Ok, lets ditch the rtl8812au-dkms

sudo apt remove rtl8812au-dkms
Install something that should work

sudo apt install git
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au/
sudo dkms-install.sh
Reboot

YEAH! Yes it is finally working! Thanks a lot!!! :D

Final question: do I need to redo this every time I update the kernel? or if it stops working after an update?

[jeremy31]

That one should work with kernel updates. It also works with quite a few Realtek chipsets RTL8812au, RTL8814au, and RTL8821au
I used it on Mint 19 and now Ubuntu 20.04 with my Edimax AC1750 USB wifi

[rpessoa]

Great! Thanks a lot! Mine is the Linksys one.

:D

This is a bit depressing ....

I had hoped that 20.04 would include support for the 8812 chipset so that we wouldn't need to use these sorts of repositories.
