As mentioned previously, the "can't access Netflix" and "extremely slow network" problems are two different things. My problem is the latter.
My ATV2 has no problem accessing things (iTunes store, Netflix, home network), but is unbelievably slow. Like many others, I get a long wait with the spinning daisy, then 3-5 seconds of a Netflix show before it kicks out back to the menu.
Also, when I rented a movie from the store, it took a long time (couple of minutes) before it came up and said "your show will be ready in 925 minutes".
So I plugged an internet cable in directly and the thing was lightning fast.
I finally called Apple and got the usual "it must be wireless interference" line from the first tech, until I told the guy I have 2 desktops, five laptops, a Mac Mini, a Sony Bravia TV with a wireless access point, a Nintendo Wii, 2 iPhones, 2 iPod Touches and an iPad that all access the network (in various combinations) flawlessly all the time, going back several years. All of those devices can stream Netflix any time, no problem, while the ATV2 is dead in the water.
I have a newish Linksys WRT160n router. He handed me over to a supervisor who fairly quickly offered me an exchange, which I'll be doing today at an Apple store. Just for the heck of it, we tried changing channels on the router, and all kinds of other crap. No difference.
So basically, the wireless on the ATV2 has minimal connectivity, and it looks like there are a few defective units out there. I'll update tonight on how the new one works, but if you haven't contacted Apple yet - do it and ask to get your unit replaced. In all likelihood it's a hardware problem.
good luck all,
dave
