Network Card for Soft Router
Network card for Soft Router might be a must if you want to swfit PC or device to Soft Router. As regular PC or Arm-device usually has only one Ethernet port, Soft Router usually needs at lease two ports: one as WAN; others as Lan.
What’s Network Card?
Network card actually is name as Network interface controller, also known as network interface controller, network adapter or LAN adapter, is a piece of computer hardware designed to allow computers to communicate on a computer network.
Because it has a MAC address, it belongs to the second layer of the OSI model. It allows users to connect to each other via cable or wirelessly. Each network card has a unique 48-bit serial number called the MAC address, which is written in a ROM on the card. Every computer on the network must have a unique MAC address. No two network cards produced have the same address. This is because the Institute of Electrical and Electronics Engineers (IEEE) is responsible for assigning unique MAC addresses to vendors of network interface controllers.
The network card used to be inserted into the computer bus as an expansion card, but due to its low price and the widespread existence of Ethernet standards, most new computers have integrated network interfaces on the motherboard.
Unless multiple interfaces are required, a separate network card is no longer needed. Even newer motherboards may contain built-in dual network (Ethernet) interfaces.
