I have done multiple iterations of on/off for both multicast and IPv6 multicast (even though I have not been running IPv6 at home.)
Results are sporadic.
For now I have turned it on and am sending a ton of shows from the HD to the Premiere so that I can put them on the ipad for an international trip coming up.
Then I am going to try putting the premiere and the stream on a (dumb) 5-port switch and push the router further upstream. The only reason that I have it is because of the wireless access point. If the switch solves the problem I might just get an AP that plugs into the switch if I need to.
