A unique feature for a router in this price range (approx US $300) is it has 2 WAN interfaces which means redundant internet connections. As of firmware version 1.3.3.5, it supports two types of QOS under "System Management" -> "Bandwidth Management", the first is a prioritization based on port and the second, a "flow control" guaranteeing minimum bandwidth.
