# 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.
{% endhint %}
{% hint style="info" %}
* 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`)
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.

###
### WAN (`eth1`)
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.
###
### WWAN (Wi-Fi Relay - Client Mode)
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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://extender.router.works/ezr13/configuration/network-interfaces.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
