this would be because u are using both 802.11n AND 802.11g. if you only need 802.11n (and you have no other older 802/11g wireless computers) u can just turn on the 802.11n capabilities of the router and have about 300mbps

On the Airport Extreme, you can be in 802.11n only mode and still have a 130Mbps link if you're still in 2.4GHz mode. For 300Mbps link, you must be in 5GHz mode.
