Certain AP models feature both Uplink and LAN1 ports. These physical Ethernet ports on your AP serve to connect the AP to your network and other devices. This FAQ aims to provide a clear understanding of these two ports.

Uplink port:

The Uplink port is used to connect the AP to your network. This could be a connection to a router, a switch, or another AP. The Uplink port allows the AP to communicate with the rest of your network and provide wireless access to it.

Typically, the Uplink port's behavior is determined by the device's overall network settings and the specific network it's connected to. The configuration is just as follows:

On step 2, Wizard setting

Or go to Configuration > Network > IP setting

Select Auto (DHCP) / Get Automatically if the AP is connected to a router with the DHCP server enabled. You then need to check the router for the IP assigned to the AP in order to access the AP in order to access the AP’s Web Configurator again.

Otherwise, select Static IP / Use Fixed IP Address when the AP is NOT connected to a router, or you want to assign it a fixed IP address. You will need to manually enter:

  • The AP’s IP address and subnet mask
  • The IP address of the router that help forward traffic.
  • A DNS server’s IP address. The Domain Name System (DNS) maps a domain name to an IP address and vice versa.

LAN1 port:

The LAN1 port is typically used to connect other devices to your AP. For example, you might connect a computer, a printer, or another network device to the LAN1 port. This port can be configured parameters such as Active/Inactive status and PVID (Port VLAN ID).

In the Port setting & VLAN configuration, the settings you adjust for "lan1" apply specifically to the LAN1 port.

Configuration > Network > VLAN > LAN setting
