OK Looks like I need to clarify -
on OS X you can share your Ethernet connection over WiFi using the computer's internal Airport card. I was wondering if I were to do that, what version of 802.11 it would share with. The reason I ask is that I will be mvong and want to utilize the maximum available speed to my new data connection and my current router is only "g" speed, and we're getting 12 mbps connection so I could use the speed of "n" and want to see if I need a new router or if I can just share from the iMac. (we have 2 MacBooks which is why we need wifi...)
