Lost WiFi with latest update {SOLVED}

Okay.

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

pi@retropie:~ $ dkms install -m 8812au -v 5.6.4.2_35491.20191025 --all
Error! You must be root to use this command.
pi@retropie:~ $ sudo dkms install -m 8812au -v 5.6.4.2_35491.20191025 --all
pi@retropie:~ $

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
pi@retropie:~/rtl8812au $ sudo dkms install -m 8812au -v 5.6.4.2_35491.20191025 --all
pi@retropie:~/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
dtoverlay=disable-bt

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!

[Addison]

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

Awesome! :D
