wifi adapter disappeared with the last kernel update of LMDE 5

[touil1976]

Hello.

I have updated my linux mint debian edition 5 with linux kernel 5.10.205-2 as suggested by the update manager. After this, my wifi adapter does not appear in the network devices anymore and I can't connect to my wifi network. This wifi adapter is a TP-link AC1300 Archer T3U Plus. Its chipset is RTL88x2BU I think.

Thanks to Timeshift, I could revert the changes, but I can't update my kernel, unless someone explains me how to fix this problem.

Thanks for your help.
Chris

What method did you use to install the driver for wifi?

[touil1976]

It's been a while I installed the driver. I think I followed something on https://github.com/RinCat/RTL88x2BU-Linux-Driver.git

[JeremyB]

I would suspect after a kernel update you would have to

Code: Select all

cd RTL88x2BU-Linux-Driver
make clean
make
sudo make install

Reboot

[touil1976]

I tried this, and it does not work !

[JeremyB]

What result for

Code: Select all

mokutil --sb

[touil1976]

Do you mean, with the new kernel or the old one that works ? I've reverted to the previous one now...
With the old kernel, it says "SecureBoot disabled".

[JeremyB]

Ok, try this in the working kernel

Code: Select all

cd RTL88x2BU-Linux-Driver
make clean
git pull

Boot into the newer kernel and

Code: Select all

cd RTL88x2BU-Linux-Driver
make
sudo make install

[touil1976]

git pull gives (in french)

fatal: ni ceci ni aucun de ses répertoires parents (jusqu'au point de montage /) n'est un dépôt git

In terminal with wifi working

Code: Select all

sudo apt install git dkms
git clone https://github.com/cilynx/rtl88x2bu.git

Reboot into non working(newest) kernel

Code: Select all

cd rtl88x2bu
sudo ./deploy.sh

If there are no errors reboot

[touil1976]

First two lines went ok.
After reboot to the newer kernel. I tried the two last lines.
It produced an error :

Building module:
cleaning build area...
'make' -j 4 KVER=5.10.0-27-amd64 src=/usr/src/rtl88x2bu-5.8.7.1.......................
cleaning build area...

DKMS: build completed.

88x2bu.ko:
Running module version sanity check.
Error! Module version v5.8.7.1_35809.20191129_COEX20191120-7777 for 88x2bu.ko

You may override by specifying --force.

depmod...

DKMS: install completed.
modprobe: ERROR: could not insert '88x2bu': Exec format error

[sleeper12]

Try what it says:

Code: Select all

sudo modprobe --force

[touil1976]

I tried to add --force to the .install.sh
Now there is no error anymore, but still no wifi adapter is appearing with the new kernel.
Problem is not solved.

[touil1976]

Has anyone any other advice ?

[sleeper12]

More details might help us. Post:

Code: Select all

inxi -Fxxxrz ; rfkill list ; mokutil --sb-state

[touil1976]

That's the result with the working kernel :
