Lots of buffering when using MOG plugin

I have a subscription to the MOG music streaming service and I'm getting a lot of buffering and timeouts when I play tunes via the MOG plugin on my Squeezebox 3. I don't get any buffering or timeouts when I play tunes via the MOG app on my PC. The I also do not get any timeouts or buffering when I play tunes on my Squeezebox when connected the Logitech Media Server.

Both the PC, Squeezebox and LMS are connected to the same router and use the same DNS. The Squeezebox is wired directly to the router and is set up to use Ethernet. LMS is version 7.7.2 - r33893

Any suggestions?
