The OP has "zorin-os-16" tag set alongside Hardware Support, so from that I assume he has Z16 not Z15.3.
I seem to remember another user solving a similar wifi problem by removing then reinserting the wifi card. I don't know if that would work, or how practical that would be for the OP on his machine. Is my recollection correct?
EDIT: This is the thread I was thinking of. Not sure if any help though.
