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.
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.

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.
Port filtering is a type of access control where access to certain Internet service are assigned to users using port numbers. This can increase security as well as restricting Internet usage.
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 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.
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.
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 (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.
IPv6 is a newer version of the Internet Protocol.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.
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.
