Ok so just to clarify.... it's only on the tablet, i assume this is your iPad, connected via WiFi to the same router that your laptop is connected to also, but you don't get this error message / problem on that.
If that's it it's not your broadband and nor is it the mcdrc server... has to be a connection problem with the WiFi / router... actually is your laptop connected to the router via WiFi also.
Perhaps you could turn off and restart your router.
