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. Note, there may be issues trying this. If the writer of the driver did not follow the correct procedures, doing the rmmod might not work at all, might cause a memory leak, modprobe may not work, the rmmod might even crash your system. Drivers, in particular Ethernet, are supposed to be tested thoroughly before being released but that is not always the case. However, if it does work let us know, I may have a way to automate this for you (been there, done that).
