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.

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.
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.
DoS protection guards a content network against DoS (Denial of Service) attacks. These flood a network with server requests, slowing overall traffic and potentially causing long term interruptions.
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.
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.
You can enable IPsec Passthrough, to allow IPsec (IP Security Protocol) encrypted/authenticated data to pass through your router, enabling increased security.
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.
