# Network Interfaces

After logging in to the router, go to `Network` > `Interfaces` To view and manage the network interfaces.

The brief information of each interface is listed under the second column, including MAC address, Rx (Download), Tx (Upload), Uptime, and IP address.

{% hint style="danger" %}
Do not `Stop` use the LAN interface or `Delete` any of the interfaces. \
It will make the router malfunction.

* The color on each interface does not correspond to its connection status.
* Rx/Tx indicates the real-time data stream instead of the speed of the internet or intranet.

### LAN (bar-lan `eth0`) <a href="#lan" id="lan"></a>

This is the physical interface of the local intranet network. It is assigned to the physical RJ45 port `eth0` by default. Refer to the below section to configure the local intranet networks.

#### Force Link

If there are multiple DHCP server-enabled devices connected, they might have a conflict in the IP address distribution. Please turn on Force Link on the LAN interface and force the DHCP server to distribute IP to its connected hosts.

### &#x20;<a href="#wan" id="wan"></a>

### WAN (`eth1`) <a href="#wan" id="wan"></a>

The `WAN` port is bound to the `eth1` RJ45 port by default, which is also used by PoE and forwarded to the LAN port on the PoE adapter. To input the WAN Internet signal from the PoE port into the WiFi extender, you can connect the LAN port on the PoE adapter to the LAN port of the Internet router.

`DHCP client protocol` It is enabled on the WAN interface, and it can automatically obtain the IP address assigned from the Internet router. If DHCP was turned off on the Internet router, please give the correct static IP for the WAN port.

### &#x20;<a href="#wwan" id="wwan"></a>

### WWAN (Wi-Fi Relay - Client Mode) <a href="#wwan" id="wwan"></a>

This is the virtual interface for the Wi-Fi relay connection. The WWAN interface will appear after successfully connecting the WiFi extender to another Wi-Fi master hotspot.
