Band new 55 inch LED Samsung network issue

I wanted to through this out there and see if anyone else has experianced this.

I just got a samsung 55" LED tv un55b8000xf. I have it hooked up to my network but I am experiancing what seems to be a lot of network issues. I am going to do some testing on my network as there are many possabilities that could be causing this. But here is what it's doing. For one I was able to connect to the internet and download/update my widgets. When I go into the youtube widget I can search for videos. But anything I try and play it tells me there was a problem and to try again later.

Also I am running the pc share software on my computer and have shared a music dir and a photo dir. I can sometimes see the comuputer but when I try and see the shared content it tries to load then gives me a message about a problem and I have no choice but to say ok and it takes me out to the main screen. But behind that message I can see that it is seeing my content.

If I go into the network setup option I have tried both manual and auto it will sometimes pass and sometimes fail.
