Lost WiFi with latest update {SOLVED}

Addison

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

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

alt text

Now, both adapters seem dead. They don't even light up for any reason to show activity.

sudo nano /boot/config.txt
And added this to the bottom of the text file some long time ago:
dtoverlay=disable-wifi
dtoverlay=disable-bt

If I change that to:
#dtoverlay=disable-wifi
#dtoverlay=disable-bt

WiFi works as intended by default.

How can I turn back on that adapter thingy though?

I don't mind going back to the old ways, but with those adapters, I get speeds about 8x faster.

Thanks ahead. :)

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

Ah nuts.

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

Sorry.

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

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

Thank you so much Mitu!
