ASUS RT-BE88U
ASUS lists the RT-BE88U as a BE7200 dual-band Wi-Fi 7 router without a 6 GHz radio, Ethernet up to 10Gbps, and with AiMesh. It is most relevant for port-heavy wired networks that primarily use 5 ghz. The main limitation to check is this: Buy it for the wired layout, not for 6 GHz—it has none.
Who it suits
Port-heavy wired networks that primarily use 5 GHz. Check the limitation above against the network you plan to build.

What the specifications mean
Wi-Fi 7 and the band layout
ASUS lists this as a dual-band Wi-Fi 7 router using 2.4 GHz and 5 GHz, with no 6 GHz radio. Wi-Fi 7 identifies the networking generation; it does not mean that every router includes all three frequency bands.
What the Ethernet ceiling means
The fastest listed Ethernet connection is 10GbE. A 10GbE port is useful only when the internet connection or local network includes compatible switches, adapters, storage, and cabling; it does not make a slower broadband plan faster.
Coverage and mesh
AiMesh is the mesh ecosystem listed for this model. Mesh can extend coverage by adding nodes, but node placement and the wired or wireless backhaul between those nodes determine how much capacity reaches distant rooms.
Multi-Link Operation
Multi-Link Operation is listed for this router. MLO allows compatible Wi-Fi 7 equipment to use more than one link, but the available bands, router firmware, and client implementation determine which links can actually be combined.
Check these before buying
These questions turn the specification sheet into a network decision.
- Confirm that BE7200 is the exact class and RT-BE88U is the exact regional model shown at checkout.
- Count the WAN and LAN ports separately; the 10GbE maximum does not describe every Ethernet port.
- Compare the router's placement with the rooms that currently have weak service before treating higher advertised throughput as a coverage fix.
- Exclude this model if access to the 6 GHz band is a reason for replacing the current router.
- Read what No subscription listed (AiProtection Pro included) gates: decide whether the free tier covers the household before paying.
- Verify the exact AiMesh models that can join this router and whether wired backhaul is available.
What we have not tested
- Throughput at different distances and through different wall materials
- Latency under mixed household load
- Firmware stability, setup flow, and subscription prompts
- Coverage relative to another router in the same physical test environment
