How to Set the WAN/LAN Port as a LAN Port on the TP-Link 5G Router in MBB Mode

In MBB (Mobile Broadband) mode, the router uses the mobile network as its default internet connection. If a wired device connected to the combined WAN/LAN port cannot obtain an IP address, the existing Ethernet WAN connection profile may still reserve that port for WAN service. Delete this profile to release the port for LAN use.

Key Takeaways

• The router is operating with MBB selected as the default gateway.
• In MBB mode, the WAN/LAN port may be reserved for Ethernet WAN, preventing wired devices from connecting.
• Deleting the existing Ethernet WAN profile releases the port for standard LAN functionality.
