Quick answer
The practical answer
Confirm the modem or ONT presents a compatible multi-gig Ethernet port and that the service plan exceeds gigabit before reserving BE67's 10GbE port for WAN.
Direct answer to the buying question
Can one Deco BE67 node dedicate 10GbE to both WAN and LAN?
No. Each BE67 node has one 10GbE port, so the primary node cannot use that same port as both a 10GbE WAN connection and a separate 10GbE LAN connection. Draw the modem, switch, backhaul, NAS, and client path first, then account for the remaining 2.5GbE and 1GbE ports.

Confirm the modem or ONT presents a compatible multi-gig Ethernet port and that the service plan exceeds gigabit before reserving BE67's 10GbE port for WAN.
Choose the 10GbE job
Decide whether the port serves WAN, a 10GbE switch, or a fast local storage path. One port cannot simultaneously be the physical endpoint for every use case.
Audit every slower link
A 1GbE wall jack path, 2.5GbE switch, USB adapter, or satellite port limits that branch. This is normal; only upgrade the branches that have a measured need.
Keep wireless expectations client-specific
Check the exact laptop or phone radio for Wi-Fi 7, 6GHz, channel width, streams, and MLO. Aggregate BE14000 speed is not one client's transfer rate.
Map the modem or ONT location, office desk, TV area, and any rooms that need wired stability.
Check WAN/LAN port speeds, wired backhaul options, and whether your internet plan actually needs Wi-Fi 7.
Count fixed devices separately from phones, tablets, and smart-home gear before buying a bigger system.
Common mistakes
Buying the fastest advertised Wi-Fi number while leaving the router in a bad location.
Ignoring Ethernet paths that could make mesh nodes, TVs, consoles, or office desks more stable.
Choosing a premium router before checking client device support, subscription features, and return path.
Category checks
Coverage claims assume ideal rooms; walls, floors, and router placement change the result.
Multi-gig ports matter only when the modem, router, switch, and client path can use them.
Mesh is easier, but wired backhaul is usually the cleaner long-term upgrade.
Decision rule
Spend more when coverage, wired backhaul, multi-gig ports, or device count solves a known bottleneck; spend less when placement or one Ethernet run fixes the problem first.
