New TV Minibox lost connection and won't reconnect, any advice?

Have you tried rebooting the TV Box Mini (turn the power off for a few seconds and then on again)?  YouView are currently investigating a bug affecting a small number of users, where it'll sometimes lose the ability to see any wifi networks.

I've fixed it, had to switch everything off a couple of times then it
worked.
