Lost WiFi with latest update {SOLVED}

@Addison said in Lost WiFi with latest update:

Happened to both of my Raspberry Pi 4s with firmware 4.8.4.

There's no 'firmware 4.8.4', that's the RetroPie version. The firmware version is the one of the raspberrypi-bootloader package. RetroPie doesn't update your firmware - how exactly did you update ?

I've been using a Nano Wireless USB Adapter (Archer T2U Nano).

This looks like it needs the rtl8812au driver - did you have it installed before the update ?

Addison

I updated all options through the console's menu system using just a controller.

And yeah, that adapter driver was installed and working correctly until yesterday.

What file or screenshot can I provide for better info on this?

What happens if you install the driver again ?

Post the output of dmesg on pastebin.com.

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

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

Well that's just hot garbage. :/

Ah nuts.

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

Sorry.

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

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.
