With more USB ports, you are able to connect more devices.
A WAN (Wider Area Network) port is most commonly used to connect the router to the Internet. It can also be used to connect to an external private network.
A higher maximum Wi-Fi speed results in better performance. This is measured in megabytes per second.

802.11n is a wireless standard released in 2009. It has faster transfer rates and improved security compared to its predecessors - a, b and g.
Dual-band devices can transmit data quickly on the newest 5GHz band, using recent standards (eg. 802.11n, 802.11ac). They can also use the older 2.4GHz band if needed.
802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability and improved power consumption. It provides advantages for gaming and HD video streaming.
With DNS relay or DNS caching, the router stores the response to queries for a short time. This means that the same query will return a quicker response if repeated from another computer in the same network.
More antennas result in increased signal strength. Devices with internal antennas often take up less space.
A network firewall protects a computer network from unauthorized access.
URL filters are particularly useful if you want to allow different web access depending on the time of day, for instance allowing employees to use personal email outside of working hours.
This is a router feature that is designed to authenticate individual users to an external server using a username and password. It is more secure and complex than WPA.
WPA2-PSK is a method of securing your network using WPA2 (Wi-Fi Protected Access 2) as well as a Pre-Shared Key (PSK) password. This was designed for home users without an enterprise authentication server.
With NAT you can use one IP address, e.g. that of the router, for a network of devices. It can increase security and make it easier to make changes to your internal network.
You can enable IPsec Passthrough, to allow IPsec (IP Security Protocol) encrypted/authenticated data to pass through your router, enabling increased security.
All DLNA certified products are compatible with one another. When different devices are connected to the same network, data can be transferred easily between them.
IPv6 is a newer version of the Internet Protocol. IPv6 operates as a separate network to IPv4, and has the capacity for more IP addresses and more features.
