# Network Interfaces

## Interface Overview

After logging in to the router, click "Network > Interfaces" to view and manage the network interfaces, as shown below. 

The background colors of the first column do not indicate their connection status; instead, they identify their firewall zones. The second column provides brief information and the connection status of each interface.

### Explanation of Terms

**Protocol** – The communication rules and methods used for data transmission.

**Uptime** – The duration of the network interface's continuous operation since the last connection. H is hours, M is minutes, and S is seconds.

**MAC** – Short for Media Access Control, a unique hardware identification number assigned to each network interface, displayed as six pairs of hexadecimal digits.

**RX** – Received (download) packets. **TX** – Transmit (upload) packets. They indicate the real-time data stream instead of the internet speed.

**IPv4** – Short for Internet Protocol version 4

i. Do not click the "Delete" button on LAN and Mobile interfaces.&#x20;

ii. Only click the "Restart" or "Stop" buttons when necessary, as this will immediately stop or pause the transmission from internet sources or related data streams.

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

This is the leading local intranet network interface assigned to the physical RJ45 LAN & PoE port and logical Wi-Fi hotspots. To configure the local intranet networks, refer to the section below.

## Mobile (wwan0) <a href="#mobile-wwan0" id="mobile-wwan0"></a>

This is the virtual interface of the 5G mobile modem.

Click the "**Edit**" button to change the mobile protocol, APN, SIM card, PIN code, etc. For more information, refer to the [Mobile Modem](/manual/firmware/mobile-modem.md) settings.

The 5G router automatically connects to the mobile network when started up. You can manually Restart or Stop the mobile modem when necessary by clicking the "Restart" and "Stop" buttons.
