[SOLVED] Wi-Fi unable to connect after updating nvidia proprietary driver (Linux mint 19 Cinnamon)

[Karrig]

The only other kernel I have installed outside of 5.0.0-17 is 4.15.0-20

[HAWR]

I think, we will then install the actual 4.15.0-52 kernel first. For that, you go back to the update-manager > view > linux kernel and then click on 4.15.0-52, which open/drop down a dialogue, where you can click on install and confirm with your password. When it is installed, reboot your system.

In the grub-menu you choose advanced option with the arrow keys, press Enter. There go to the line with 4.15.0-52 generic at the end and press Enter again. Then the system boots with that kernel, just as you already know it. On the following website you see pictures of the grub-menu and the advanced options (simply replace Ubuntu with Linux to understand).

https://askubuntu.com/questions/1014634 ... ns-in-grub

When you are back to Cinnamon, you go to the linux kernel in the update manager, choose the 5.0.0-17 kernel and remove it. We do this to prevent the system from rebooting with this kernel next time (automatically the system boots always with the "highest" kernel installed).

If that is done, you can apply the codes one by one JeremyB wrote down (you already know how to proceed with password and enter). I think it's easier to copy each code and paste it into the terminal. Of course, if there appear error messages, report them here.

[Karrig]

Thanks again for the help both of you.

I managed to install the 4.15.0-52 kernels without any issues except wi-fi not being able to connect again. Used phone as usb adapter to be able to follow the steps JeremyB posted. However on the second step this happened:

Code: Select all

git clone https://github.com/Mange/rtl8192eu-linux-driver.git
fatal: destination path 'rtl8192eu-linux-driver' already exists and is not an empty directory.

I tried a while back to do a solution that involved updating the drivers through the terminal and I presume this is because of it? Should I try to skip this step, delete the folder there and run it again?

[JeremyB]

Delete the folder and try again or just cd Desktop and run all the commands

[Karrig]

I deleted the folder and cloned it again, then on step three it gave me this error:

It looks like you have done

Code: Select all

echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf

Reboot

[Karrig]

Rebooted, wi-fi works once more, tho the strength issue is still there.

Should I edit the post as solved?

[JeremyB]

Signal strength might improve if wifi power management is disabled

Code: Select all

echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/8192eu.conf
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot

[Karrig]

Did that, wi-fi unable to connect again.

[JeremyB]

This will undo that change

Code: Select all

sudo rm /etc/modprobe.d/8192eu.conf
sudo sed -i 's/wifi.powersave = 2/wifi.powersave = 3/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Still unable to connect
