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

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.
With more USB ports, you are able to connect more devices.
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.

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.
A network firewall protects a computer network from unauthorized access.
Static IP addresses remain consistent on each connection. This means the IP address can be used to allow remote access/configuration. Most home devices have a dynamic IP address, whereas larger companies usually use a static IP address.
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.
This is a security feature in which network access is granted to devices based on their unique MAC address. It can provide increased security, but it can be a risk if the user loses the device.
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.
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.
