I've got a problem that seems to be caused by the introduction of a RB250GS into my home network.
What works: Fiber to the home, ONT to Actiontec router, IPTV STB plugged directly into the router
What doesn't: RB250GS in between the Actiontec router and the IPTV STB
The IPTV uses the Microsoft Mediaroom platform and my understanding is that it uses unicast when changing channels (a burst of fast buffer filling) then multicast for regular reception once everything's caught up.
It worked fine at first - no problems watching or recording anything. I installed the RB250GS (running 1.6) in between the wall outlet and the STB, then also plugged in my Xbox. This seemed fine for about a week, then things started getting glitchy. Sometimes watching TV would freeze, stutter, go all pixelated etc.. The same applied to recording TV - programs would be all glitchy to begin with and sometimes you could fast forward a few minutes in and it would settle down and be watchable, other times it would be a bad recording all the way through.
I'm confused because this setup worked fine for a while it seems, then started acting up. My gut reaction is always to ask "what changed?" but in this case I think the only thing that changed was the IP address of the RB250GS and the description on the SNMP page. I've power cycled it a bunch of times and got to the stage where I could reproduce the problem when it was connected, and was problem free when it wasn't. Frustrating!
I've got a few more RB250GS's kicking around, so I'm going to switch the unit out for another one and see how it behaves.
Does anyone have any ideas on anything that could be config-related and causing this problem though?
Thanks in advance
