Strangely enough, my internet connection is faster than my internal 802.11g WiFi network.
My internet connection is > 25 Mbps. My "54 Mbps" 802.11g WiFi maxes out at around 22-23 Mbps, and drops below 20 Mbps in the same room but 15 feet away. At a more significant distance it may drop below 10 Mbps. (I don't use "Super G" 108 Mbps since my Macs are not compatible with that, as it's non-standard.)
The good news is that Netflix HD should be less than 10 Mbps, but obviously if your internet connection is only say 6 Mbps to begin with, then your internet connection would be the limiting factor unless you're sitting very far away from the WiFi access point.
