Forwarding by DHCP MAC address instead of by IP address (that way servers wouldn't need a Reservation or a static IP)
Accurate automatic uplink detection when the ISP uses upload PowerBoost. (Currently, upload PowerBoost causes the device into thinking that there is more uplink bandwidth than there actually is available long-term.)
QoS method that allows users to take advantage of upload PowerBoost. (Currently, users with PowerBoost ISPs who have set their uplink speed to reflect their long-term reliable bandwidth are speed limited)
