Yes, doing anything to cause the NIC to reset may get it working again.
However, I didn't know computers (other than phones) had an Airplane
mode. Another thing that could be tried would be to rmmod the wifi driver
and then modprobe it back. This is obviously heavy handed, and the real
problem should still be investigated, but may get it online again which
is what the OP has asked for.
Thanks for the suggestion.
I'll try rmmod next time it happens
(though it sounds a bit dicey to me, like pulling out the plug
while a printer is in the middle of printing).
