My M1000 is connected directly to my router via Ethernet; I use it to listen to Internet radio.
Sometimes (usually in the evenings when everyone in the neighbourhood is online) it will constantly stop playing to rebuffer - it will play for only a 15 or 20 seconds before stalling again.
iTunes, on iMac on the same network plays happily without interruption.
I'm assuming that the M1000 has a smaller buffer than iTunes, and that iTunes is able to deal with occasional network issues better.
Is this likely to be the case? Is there anything I can do about it?
