To put it simply, a wireless router is a terminal, which is equivalent to the computer we commonly use, and the wireless router is nothing more than a difference in the transmission medium.

The set up wireless router will complete Internet access by obtaining an IP address (PPPoE, dynamic IP or static IP) for accessing the Internet, establish a link that can access Internet resources normally, and then use some technology (NAT) to enable the devices connected to the wireless router to access the Internet normally.

It also has some other network management features, such as DHCP service, NAT firewall, MAC address filtering, dynamic domain name, etc.

The signal range of a general wireless router is 50 meters in radius, and some wireless routers have a signal range of 300 meters.

A wireless router is simply something that can be connected to the Internet using a wireless network card within its signal range.

Just like after the mobile base station is set up, the mobile phone can be allowed to talk normally within a certain range.

The wireless network card and the wireless router are used together, and the advantage is that there is no need to pull the network cable, and there is no need to pull the network cable in a set of rooms, upstairs and downstairs.
