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.

EZR35-5G Router's Network Interface Overview

### 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 {% hint style="warning" %} i. Do not click the "Delete" button on LAN and Mobile interfaces. 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. {% endhint %} *** ## LAN (bar-lan) 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. {% content-ref url="/pages/b2G8Hxpgklg1GEE7B5ZW" %} [Local Networks](/manual/firmware/network-interfaces/local-networks.md) {% endcontent-ref %} ## Mobile (wwan0) 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. {% content-ref url="/pages/Eu37iFk1WTSgWfoX3uoB" %} [Mobile Modem](/manual/firmware/mobile-modem.md) {% endcontent-ref %} ## WWAN WWAN stands for Wireless WAN (wireless wide area network). They are the virtual interfaces for wireless Wi-Fi relay connections on 2.4GHz and 5.8GHz frequency bands. {% content-ref url="/pages/oNYiRbmdaLtxv1BjExx8" %} [Wi-Fi Hotspots](/manual/firmware/wi-fi-hotspots.md) {% endcontent-ref %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://outdoor.router.works/manual/firmware/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.
