Installed zorin pro about two months ago, was working fine. This is on Lenovo X1 Carbon.
I got a request to update firmware v15 something - i forget to look closely, just following the prompt.
Now internet will no longer work.
The machine is a dual boot with windows 10. At first I could still connect to internet through Windows. Now that also no longer works...
So it must be a firmware issue?
Wifi DOES connect fine. Afaik there's no firewall blocking it.
USB tethering did work, now not anymore.
How can I find the firmware version currently installed?
I ran a Lenovo update inside the Windows 10 tha came pre-installed on the device.
That fixed the internet issue for Windows. Zorin still doesn't connect to internet.
I found that the DNS points to 127.0.0.53 only.
When I add any other DNS in the Network settings screen, it doesn't get updated
at the TOP of etc/resolve.conf the issue is gone.
BUT each time the laptop goes to sleep, it stops working and I manually need to enter it again.
Adding it via the UI (settings -> Wifi -> ipv4 -> "DNS") makes no difference, it gets deleted on-sleep each time.
