WNR 2000 v3 won't stay connected to Netflix on Vizio TV Apps

I have a WNR 2000 v3 router and I can't find any support that fixes my connectivity problem with both my Vizio TV and nd my LG bluray player. I can connect to other applications just fine but Netflix, Vudu, and Web Videos apps don't connect. What is real wierd is I can view sample videos on HuLu Plus just fine!!! And all of the non-video apps seem to work just fine. I have great signal strength and my laptop that is on the same network streams video on my HDD's just fine so I'm not getting what the problem is? I would like to figure out this as it has driven me crazy for the past week! Any help would greaetly be apreciated. Thank you in advance!
