Apple TV streaming and airplay trouble?

Hi all

Ok so I've read numerous threads and troubleshooting on this subject and it seems to be a running theme.

So I'll start with my issues

My Apple TV has a hard time consistently streaming netflix or connecting with airPlay (unless I am playing something off of YouTube or showing pictures)

The audio is patchy

TV and movies won't load

No error sign shows up the wheel keeps spinning

My tv and phone have both been updated

I've tried restarting numerous times

My Apple TV is literally right on top of the wireless modem

The signal strength is strong on all devices

I've tried unplugging my modem

I've tried air playing itunes, soundcloud, 8tracks and grooveshark but only YouTube works consistently without fail

My netflix is not logged in to any other devices

However When I do log on with other ones (my computer or ipad) it works fine

Even when nothing else is on the wifi network I still have trouble

-Sometimes- it works fine but I don't know why as I haven't done anything different

And it's not just this appleTV, I have a second one that responds in the same fashion

Any ideas short of physically connecting the appleTV directly into the modem?
