Namebench says my Internet can be 103% faster. Real?

I don't know if I should trust the result since I am already using OpenDNS and very happy with the speed thus far.

I ran benchmark on the desktop (where the comcast router and netgear 802.11G wireless router are connected), it's 30mps down, 6mps up. Nice. Then I ran benchmark on my MBA, it's 14mps down, 6mps up. Not as good. But still, I am happy with the speed, and I suspect the netgear wireless router might be the bottleneck here. Will I see a major improvement with a N-capable wireless router?

Finally, I ran Namebench a couple times, each time it suggested a different server, so I am not sure how reliable it is. Can someone speak from his experience?

No, not asking to increase the DL speed. Just wondering how true and reliable the 103% number is.

I see Namebench suggest one server for primary and another for secondary. I realize I need to catch up with wireless technology, but what does this do? Isn't secondary just a backup to the primary (in case the primary server isn't available)? What's teritiary server anyway? I don't see an option to set it up.

I think G is capable of 54mps (theoritically speaking), so the real world speed is more in line of 14mps? What about N and its real world performance? I need to catch up on wireless technology.

So the 103% only represents how quickly the domain name gets resolved? I imagine that number is very small to begin with.

Just out of curiosity, how often do you get "page not load" using the google dns? With OpenDNS I average once every 200 loads.
