No network data on Mint

[Cooyal]

I have read in this forum of a number of people having issues connecting to wifi on Mint - but they all seem to be different to mine. When I type: inxi -Fxz, and scroll through the list, for Network it says “No device data found”. How can I solve this? Am new to Linux - would appreciate help. Thanks

we would also like to look at that inxi -Fxz output
