It sounds like you removed some previous installed packages with this apt full-upgrade command. I never run this command myself. I usually stick to apt upgrade or apt dist-upgrade
while āapt full-upgradeā command is used to do the same thing except if needed previously installed packages are removed to make the upgrade happen.
Did you install a driver for this WiFi adapter manually?
If so, I am afraid you need to repeat that procedure one more time.
Thanks for the reply @FrenchPress . I had no idea there was a difference or that I shouldn't be using "full-upgrade". Wifi was working when I first installed, so I haven't a clue how to install it now.
I also learnt such things in past hard way.
I am still traumatised from DD command which went wrong
Linux commands could be very powerful.
Use it with utmost caution
You may need to experiment based on what build you have.
Hold the left shift key or tap it vigorously to see the Gub Menu with Advanced Options for Zorin
If that just does not work, try tapping the esc key instead of left shift key.
Once you see Advanced Options for Zorin, arrow key to it and hit enter. Now, error key down to the kernel version 5.11.0-38 or any prior to -40. Hit enter.
DKMS helps to assign the Wifi (Or graphical or other driver) to the Modules in the kernel if the kernel changes. Without DKMS, a change in the kernel can cause the driver to not be read or not be read properly.
Most drivers do not need DKMS, but some wifi manufacturers have no respect for Linux at all and code only for Windows.
I have a dual boot, so that was no problem. However, whenever I tried to log in through the advanced options from any other kernel version, it went straight to the ttyl screen. After 4 tries I gave up. Gah!!
Thanks for explaining DKMS. Dell is pretty linux friendly. They even offer "off the shelf" computers with linux installed. I have no idea what caused this issue.
The only way I was able to fix it was by restoring my backup from yesterday. So frustrating, but at least it's working again. SO APPRECIATE your help guys!!
