Head-to-head
ASUS RT-BE88U vs RT-BE9700: More cables or a compatible 6 GHz laptop?
The short answer
Choose RT-BE88U if more than four wired devices need to stay connected without a separate switch. It leaves eight copper LAN sockets after 10G WAN. Choose RT-BE9700 for a compatible 6 GHz laptop when four local sockets are enough. It also includes a wall-mount kit. BE88U has no 6 GHz radio, while its extra 10G connection is SFP+ and needs compatible hardware. Both have one USB socket.
Before you choose
The reasoning and the trade-offs
A wired node can be the cable that makes the smaller port budget fail
A work computer, NAS, console and TV already occupy BE9700’s four local sockets after WAN. Adding a wired AiMesh node makes five local connections, so the room needs a switch or another route. BE88U leaves eight copper local sockets, including four 2.5G ports. That can simplify a wired-heavy household without making every device faster. If a supported node uses wireless backhaul or an existing switch already handles the cables, the extra port count becomes less decisive and BE9700’s 6 GHz option may matter more.
What this is based on
Four ordinary local jobs plus a wired expansion node crossed with LAN counts after WAN. Backhaul consumes a local socket, and an existing switch changes the recommendation.

About this comparison
ASUS RT-BE88U vs RT-BE9700 for a mixed home network. Compare the real LAN count, 6 GHz compatibility and the hardware behind a second 10G link.
These ASUS routers overlap on a 10G Internet connection, multiple 2.5G local sockets and AiMesh. A household choosing between a wired-heavy layout and a newer tri-band layout has a real trade to resolve.
Winner by situation
Start with what you need it to do
Five or more direct local copper connections
BE88U leaves eight after 10G WAN.
- ASUS RT-BE88U
- Better fit
- ASUS RT-BE9700
- Caution
A compatible laptop needs 6 GHz at the main router
Only BE9700 has that radio.
- ASUS RT-BE88U
- Caution
- ASUS RT-BE9700
- Better fit
6 GHz is needed at an older dual-band node
Changing the main router does not add a radio to the old node.

What matters in practice
The differences that matter
A wired node can be the cable that makes the smaller port budget fail
A work computer, NAS, console and TV already occupy BE9700’s four local sockets after WAN. Adding a wired AiMesh node makes five local connections, so the room needs a switch or another route. BE88U leaves eight copper local sockets, including four 2.5G ports. That can simplify a wired-heavy household without making every device faster. If a supported node uses wireless backhaul or an existing switch already handles the cables, the extra port count becomes less decisive and BE9700’s 6 GHz option may matter more.
How we reached this conclusion
Four ordinary local jobs plus a wired expansion node crossed with LAN counts after WAN. Backhaul consumes a local socket, and an existing switch changes the recommendation.
The old node does not inherit the new router’s band
BE9700 supplies 6 GHz at the main router. A compatible laptop may use it nearby, but an older AiMesh node with only 2.4 and 5 GHz radios does not become a 6 GHz access point. A household buying the router for a workroom served by that old node should check the whole route before choosing. BE88U has no 6 GHz radio anywhere in its own hardware. The useful question is which device connects to which access point, rather than whether the network name stays the same.
How we reached this conclusion
A remote workroom served by a reused node plus a new compatible laptop crossed with physical radio capability. AiMesh support does not add absent node hardware.
A second 10G connection changes the parts list
If a 10G Internet service and a 10G NAS must connect separately, BE9700’s single 10G socket cannot cover both. BE88U offers SFP+ in addition to its 10G copper connection, but the NAS interface and supported transceiver or DAC determine whether that solves the job. Include the part, its space and cable requirements before comparing offers. On a slower Internet service with only one fast local device, the extra connection may add no useful function. Port ratings still do not predict the NAS’s actual file speed.
How we reached this conclusion
Separate high-speed WAN and storage plus existing endpoint interface crossed with single 10G versus RJ45 plus SFP+. Compatibility and storage performance bound the inference.

Meaningful differences
What changes the fit
| What changes | ASUS RT-BE88U | ASUS RT-BE9700 | Why it matters |
|---|---|---|---|
| Local copper after 10G WAN | Four 2.5G and four 1G. | Four 2.5G. | Ordinary TV, printer and console cables can consume the spare sockets even when their speed needs are modest. |
| 6 GHz devices | No 6 GHz radio. | Tri-band with 6 GHz. | An unused 6 GHz-capable laptop cannot borrow that band from BE88U. |
| Extra 10G route | SFP+ alongside the 10G RJ45. | Only one 10G WAN/LAN socket. | Count the required module or cable before treating two connectors as a finished path. |
| USB and placement | One USB 3, AiMesh. | One USB 3, AiMesh, wall-mount kit included. | Neither gives two direct USB attachment sockets. |
What you give up
Every choice has a cost
If you choose ASUS RT-BE88U
- SFP+ may require another component and its compatibility check.
If you choose ASUS RT-BE9700
- A fifth wired device needs another route, and one USB port still limits direct attachments.
Recommendation switch
The decision flips if...
More than four wired endpoints must connect directly
Choose ASUS RT-BE88U. BE88U has the larger cable budget.
Four local sockets are enough and a verified client needs 6 GHz
Choose ASUS RT-BE9700. BE9700 adds that band.
What matters in practice
Before you choose
The router with more cable connections is not the one that adds a 6 GHz radio.
What this comparison cannot tell you
- No measured whole-home coverage claim.
- No universal SFP+ module compatibility.
- Neither has two direct USB sockets.
