With more LAN ports you are able to connect more computers to the network directly using LAN cables.

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.

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. External antennas can be repositioned in order to improve the signal, and replaced with a longer antenna if needed.
The antennas can be removed if they are not needed, or replaced with longer ones if necessary.
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.
You can enable IPsec Passthrough, to allow IPsec (IP Security Protocol) encrypted/authenticated data to pass through your router, enabling increased security.
You can enable L2TP Passthrough. L2TP (Layer 2 Tunneling Protocol) is a VPN (Virtual Private Network) protocol for carrying data from one device to another securely over the Internet.
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 PPTP (Point-to-point tunneling protocol) Passthrough. This allows VPN connections using PPTP to pass through the router with ease. This method is less secure than L2TP passthrough.
With (QoS) Quality of Service, you can optimise performance by deciding which traffic to prioritise when a bottleneck occurs. You can decide which traffic is important based on things like IP address and type of Internet service.
Universal Plug n Play (UPnP) is a set of networking protocols that permits networked devices, such as PCs, printers, Internet gateways, Wi-Fi access points and mobile devices to find each other and exchange information on the network.
Static routing is a simple form of routing, recommended if you have just one, or a small number, of routers to connect. They need to be configured and updated manually.
Inter-VLAN routing is a process of forwarding network traffic from one VLAN (Virtual Local Area Network) to another VLAN using a router.
