I have used Zorin 15 Lite for a few years without any issues. I have just tried Zorin 16 (running from USB) and - it looked good - so I decided to install it. After installing and connecting - initially - to the internet (AFAIK) my Wi-Fi was disconnected and reports (!) "WiFi is disconnected".
I did briefly see a popup (or something) that reported that Airplane Mode was set. But I cannot now find that screen/app/whatever.
Fearing incompatibility with Zorin 16, I attempted to re-intall Zorin 15 (via fresh bootable USB, etc) and did a full installation. While all functions are useable, the Wi-Fi remains disconnected.
I am a 'mere user' and although I have looked for a setting to enable Wi-Fi but I cannot anything.
The computer is an elderly HP635.
Is there an easy fix to this? So far, re-installing doesn't help. Many thanks.
