Step 3. Configuration LAN system via WiFi

To set up and configure the internal LAN via WiFi, businesses need to perform the following steps:

Router configuration:

  • Set WiFi network name (SSID) and the password is strong enough (including special characters, uppercase letters, numbers).
  • Channel settings WiFi to avoid interference (use channel 1, 6 or 11 for 2.4 GHz frequency band).

Security settings:

  • Enable encryption WPA3 to protect the connection from network attacks.
  • Turn off WPS if not necessary, to avoid security holes.

Connect the terminal: IP address allocation static or dynamic (DHCP) for the device to easily connect with each other.

Practical example: A small business can install VLAN to separate network traffic and internal customers, ensuring data security.
