I recently bought a used laptop and I installed Zorin 17. There were some problems (booting, battery) but the wifi was working. After consulting with a laptop service we changed the battery, the BIOS battery, and the SSD, and reinstalled Zorin 17 from scratch on the brand new Kingston SSD. Now under Zorin the wifi is not working : if I investigate my settings it says "No Wifi adapter found", and when I press the physical key to switch the wifi on it remains off. It was tested in the service by booting from a Windows external disc, and under Windows the wifi worked fine.
I attach a screenshot of some investigation I did based on info found elsewhere in this forum. To me it is suspicious that WWAN is "disabled" - shouldn't it read "enabled" for me to use wifi? If so, how do I turn it on? Thanks.
