Help? Bought brand new...can't get it to work right.

I'm not entirely sure. The tech support guy was hard to understand (I think we had a language barrier going on. He couldn't understand me, and I couldn't understand him LOL!) But it seemed like he was trying to get me to find my ISP's DNS because this was something to do with Parental controls. Thing is, I didn't see that in the setup steps at all, and I am certainly not about to go fiddling around with the DNS settings without knowing what the heck I'm doing. But even still? When I went to Open DNS website and registered for it, on step one, it tells me to go to routerlogin.net website. When I go there, it tells me I don't have connection to my router. *head scratching* I am totally lost on that. I have a field technician coming back out on Monday to move my radio to the other side of my house, because my ISP is moving me over to a closer tower for better connectivity. When he comes out, I will ask about this DNS stuff, but without being able to get past the whole step 1 business, I'm still not sure how to get this all going. I didn't think this would be so dang complicated. With LinkSys, it was literally plug in, and go. Nothing about DNS's or whatever was ever needed. The parental controls were built right into the firmware. (Were being the keyword here, as suddenly...that stopped working, hence how I come about buying a NetGear).
