[Nils0101]

just found this post: viewtopic.php?t=302603

could the secure boot in the bios be the problem?

If yes, how could I change it? Would you recommend changing it?

[sleeper12]

You don't seem to have secure boot. JeremyB will know better than me, but try:

Code: Select all

 sudo modprobe rtl8821ce 

[Nils0101]

You don't seem to have secure boot. JeremyB will know better than me, but try:

Code: Select all

 sudo modprobe rtl8821ce 

modprobe: ERROR: could not insert 'rtl8821ce': Device or resource busy

[sleeper12]

Maybe:

Code: Select all

 sudo modprobe -r rtl8821ce && sudo modprobe rtl8821ce 

[Nils0101]

Maybe:

Code: Select all

 sudo modprobe -r rtl8821ce && sudo modprobe rtl8821ce 

same

[sleeper12]

Ok, best wait for JeremyB to return then as I'm stumped.

[Nils0101]

git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout extended
make
sudo make install
sudo modprobe -r rtl8822
sudo modprobe rtl8822

could this work?

No, that's the wrong driver.

thanks - I guess I 'll wait

What about results for

Code: Select all

dmesg | grep 8821ce

The lsmod results showed a driver is loaded
It can't be Secure Boot as it shows you are using Legacy(BIOS) boot

[Nils0101]

I need to get some rest - I have to teach in the morning.
Be back in the morning - thanks in advance

[JeremyB]

Code: Select all

sudo dkms uninstall rtl8821ce/v5.2.5_1.26055.20180108.1
sudo dkms remove rtl8821ce/v5.2.5_1.26055.20180108.1 --all

Reboot and hopefully the other version you have built works

[Nils0101]

it works -thank you so much!

Thank you for taking your time and guiding me through that problem!

[Nils0101]

Is there a way to prevent it from happening again with the next upgrade? Something to keep in mind?

Do I understand it correctly that you (I) deinstalled some part of the newer distri and now that part is working on the old one?

Thank you so much!!
