When I switched on my Roberts 93i wifi radio today it's display said 'connecting' then 'loading', but didn't. It then said 're-connecting' but didnt and eventually timed me out. The same thing happened on my Roberts stream 107 in another room.
However I also have a fairly new BoomBocs wifi radio and that seems to be working normally!

I've tried all the obvious things, like disconnecting the radios from the mains and switching on again, switching off the modem and rebooting it etc. The Boombocs re-connects but neither of the Roberts receivers do. It's not an Internet problem, as I can get the radio through both desktop and tablet computers.

Any ideas?
(I think Roberts use Airable software for their radios, not sure what BoomBocs use).
