access point question

[#1]

What is the point of a 300n access point if it has a 100 mbps ethernet port on it
Surely you are then limited to 100 mbps!!!!
So no benefit over a 150n access point
What am I missing?

[#2]

A 300n will just about max out a 100Mb ethernet connection due to WIFI overheads, the 150n (at 75Mbps each way, less overheads) is less than fast ethernet (100Mbps each way).

thanks
so it might be worth getting an access point then as at the moment i only connect at 130 mbps as this is the routers default and changing it to 300 comes with warnings about interferinng with other wifi points
thanks again
