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 higher maximum Wi-Fi speed results in better performance. This is measured in megabytes per second.

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.
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.
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.
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 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.
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.
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.
Dynamic routing is useful if you need to configure several routers, as they can automatically find network destinations and best routes, as well as sharing information between routers. They can reroute automatically if there is a fault somewhere.
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.
