XPL2000 Won't Connect to Internet via Cable and WiFi

[Miles]

A XPL2000 suddenly stopped connecting to the internet. It wouldn't connect via cable nor WiFi. It "sees" the WiFi name but would fail to connect even the password is entered. This box works without any issue for almost a year. Is there any software update for the last few days?

Have you tried rebooting everything, the modem, router and the Buzz?
