This snafu is oddly reminiscent of the under-reported incident a couple of years ago when Google emitted a Chromecast update which rendered them unable to connect to networks powered by TP-Link branded routers (it really was that specific). After a few weeks they issued a patched version of the firmware but that still meant those with stranded devices having to jump through hoops to connect them to an entirely different network briefly to receive the OTA fix.
