Every computer that wants to form a local area network must have a wireless network card hardware device. Especially for desktop computers, wireless USB or PCI slot network cards need to be purchased separately. You also need a wireless router.

First, connect one of its computers to the wireless router through a network cable, and then log in to the router management interface according to the login address and account information on the back of the router.

Then in the router management interface, firstly, the settings are made according to the internet access mode provided by telecom operators. Switch to "WAN interface" and select "WLan port connection type" according to the connection type provided by the telecom service provider. If the telecom service provider provides static IP address login mode, it will log in according to the IP related information provided.

Start the DHCP server to meet the access of any wireless device.

Click DHCP server →“DHCP service, and then check "Enable DHCP service" on the right to set the start address and end address of the address pool. We can set it according to the number of computers connected to the current router.

Finally, turn on the wireless hotspot: switch to the "Wireless Settings" tab, set the SSID number, check the "Turn on wireless function" option, and finally click "OK" to complete the setting.

Finally, you can turn on the wireless switch in the computer. If there is a wireless hotspot sent by the wireless router at this time, the computer will search for the signal and can connect.
