You cannot add the same module/version combo more than once.

Seems like the module is already installed and the re-installation fails. What's the output of

dkms status

dmesg that you requested:
https://pastebin.com/mkfFKb2D

I don't see anything related to the WiFi adapter here. By default RaspiOS will disable the WiFi if the ethernet adapter is connected, which is what I see from your dmesg . Have you tried booting without the wired network connected ?

Yeah, I had to ethernet cable both Pis so I could change the config.txt file to:
#dtoverlay=disable-wifi
#dtoverlay=disable-bt

I don't know what I'm doing but thought that was at least a way to get WiFi back again.

Have you tried booting without the wired network connected ?

Yes, and I received something like a "No wlan0 interface detected" on them both.

I understand nothing. :D

I see that xpad has been added for the latest kernel, but the 8812au has not.
Remove the driver:

sudo dkms remove 8812au/5.6.4.2_35491.20191025 --all

and then try to re-install it again. If you get an error during installation, then post the log file from the build - dkms will show you where it is.

The preview for this post seems to show extra large fonts a few times for some reason.

That wasn't from me.

No idea how that came to be.

My apologies ahead for any unnecessary font weirdness on this site. :P

"and then try to re-install it again. If you get an error during installation, then post the log file from the build - dkms will show you where it is."

I don't know what that means.

I need something to copy and paste because I am too stupid to live.

OK, so it fails here and it's probably why it was not automatically installed during the kernel upgrade.

Try running

dkms install -m 8812au -v 5.6.4.2_35491.20191025 --all

from the source folder and see if it gets installed.

Addison

Okay.

dkms install -m 8812au -v 5.6.4.2_35491.20191025 --all

Nothing seemed to have happened unless I phrased the terming wrong.

I can only upvote 6 posts per day here?

Well that's just hot garbage. :/

Addison

Ah nuts.

Just realized you requested to install that from the source folder.

Sorry.

pi@retropie:~ $ cd rtl8812au

Have I done that correctly?

Yes, but I think it doesn't matter. Is the wireless driver still not installed ? You can check with sudo dkms status to see if it was installed for the current kernel (5.10.103).

Addison

Unsure what this all means.

It's still not installed. I wander though if you're not actually seeing the same issue with https://retropie.org.uk/forum/topic/34200/.
Add arm_64bit=0 to your /boot/config.txt , reboot and then try again installing the driver.

Addison

At the end of /boot/config.txt (currently showing with your suggested update):

[all]
#dtoverlay=vc4-fkms-v3d
#overscan_scale=1
arm_64bit=0
dtoverlay=disable-wifi

Remove the module again with sudo dkms remove 8812au/5.6.4.2_35491.20191025 --all and re-run the installation, but just the last step.

Joy!

Think it took this time. :D

Going to unplug my ethernet cable now and do this for my other Pi as well.

Thank you so much Mitu!

Other Pi is now back to faster wireless speeds as well.

Awesome! :D
