YouTube videos fail over AirPort
For the past couple days, videos played via YouTube app or web site in Safari all iOS devices fail after the initial hunk (usually just several seconds) has played. No more data will buffer. Changing the playhead to another location doesn’t cause it to load. Just sits and spins.
I’ve restarted the cable modem, updated the AirPort’s firmware, restarted devices, etc.
Macs can play the same videos in Safari by both Ethernet and AirPort.
Is this a bug in something or is there something I can try? All iOS devices are up to the current version, whatever that is this minute.
