When setting up a 5G CPE router or WiFi 6 router, users often focus on wireless performance, chipset, and antenna design. However, the Ethernet ports—specifically the WAN port and LAN ports—play an equally important role in ensuring reliable and flexible network connectivity. Understanding their functions helps both home users and IT professionals make the most of their networking equipment.
The WAN port (Wide Area Network) connects your router to the internet. It typically links the router to a modem, fiber connection, or upstream gateway.
² Function: Brings internet access into the router.
² Typical Label: Often marked as “WAN” or distinguished by a different color.
² Example: In the SUNCOMM SE06 5G CPE Router, the WAN port allows users to connect the device directly to a fiber modem while still using its 5G module as a backup.
A small office uses the WAN port to connect to a fiber broadband service. If the fiber connection fails, the router automatically switches to its 5G network for uninterrupted service.
The LAN ports (Local Area Network) distribute the internet connection to wired devices such as PCs, smart TVs, or gaming consoles.
² Function: Provides stable, low-latency connectivity within the local network.
² Typical Label: Marked as “LAN” and often found in multiple numbers.
² Example: The SE06 router features dual 2.5G LAN ports, ensuring ultra-fast connections for bandwidth-heavy applications like cloud gaming and 4K video streaming.
A gamer connects their desktop to the LAN port for lag-free gameplay, while other family members use Wi-Fi. This ensures the gamer’s connection remains stable and unaffected by wireless congestion.
Feature | WAN Port | LAN Port |
Connection | Links router to the internet (external network) | Connects router to local devices (internal network) |
Direction | Incoming internet traffic | Outgoing internet distribution |
Number | Usually one | Multiple |
Example Device | Fiber modem, 5G base station | Computers, smart TVs, printers, gaming consoles |
² Reliable Wired Connectivity – Even with strong Wi-Fi, wired connections via LAN ports remain unmatched for low latency and stability.
² Hybrid Networking – WAN ports enable routers to combine wired broadband with 5G backup, ensuring uptime in mission-critical environments.
² Flexibility for Enterprises – Businesses can connect servers, VoIP phones, and security cameras directly through LAN ports while maintaining internet access via WAN.
² Optimized Gaming and Streaming – LAN ports eliminate wireless interference, giving gamers and streamers consistent high-speed performance.
The SUNCOMM SE06 5G WiFi 6 Router offers:
² One 2.5G WAN port for stable broadband connectivity.
² Two 1G LAN ports for ultra-fast wired connections.
² Automatic failover between WAN and 5G to guarantee uptime.
² Support for both router mode and bridge mode, giving users flexible networking options.
This design ensures the SE06 adapts seamlessly to both home networks and enterprise applications.
The WAN and LAN ports are fundamental to router functionality, enabling both internet access and local connectivity. A well-designed router, like the SE06 5G CPE with WiFi 6, combines high-speed wireless features with robust wired options, offering users the best of both worlds.
Whether you are a home user needing stable gaming connections or an enterprise seeking reliable failover solutions, understanding the role of WAN and LAN ports ensures you make the right choice in networking equipment.
