Ocean Internet Radio keeps dropping out

[Airlane1979]

I've bought a reconditioned Ocean Digital WR261 internet radio. Although my broadband is at least 30Mbps and the wifi meter on the radio shows a good signal, it has terrible problems connecting to any station at all. I just get Buffering..., maybe a few seconds of audio then it drops completely with a message Station Connection Unavailable. I've had contact with the company who have no idea why this is and have given me a partial refund, so the radio really cost me very little as it was cheap to start with. But I'd prefer to have a working radio.

Any advice?
