ASUS RT-BE9700 vs TP-Link Archer BE400: Which Router Fits Your Network?

The RT-BE9700 is the feature-fit option if you specifically need a 6 GHz band and its 10 Gbps/2.5 Gbps port arrangement suits your topology. The Archer BE400 is a reasonable fit if 2.4 and 5 GHz cover your planned client use and its dedicated 2.5 Gbps WAN plus mixed-speed LAN ports map cleanly to your devices. Neither specification sheet establishes which router will be faster or cover a home better.

The buying question

Do you need the RT-BE9700's documented 6 GHz band and its different multi-gig port layout, or does the Archer BE400's dual-band layout and dedicated 2.5 Gbps WAN fit your devices and wiring plan?

The RT-BE9700 lists 2.4, 5, and 6 GHz bands and a 10 Gbps WAN/LAN plus several 2.5 Gbps ports; the Archer BE400 lists 2.4 and 5 GHz and a dedicated 2.5 Gbps WAN with mixed 2.5/1 Gbps LAN ports. These are configuration differences, not measured speed or coverage results.

Quick verdict

Choose ASUS RT-BE9700 if

  • You have compatible 6 GHz clients and intend to use a third band.
  • Your planned wired layout benefits from a 10 Gbps WAN/LAN port and three dedicated 2.5 Gbps LAN ports, with the WAN/LAN role assigned deliberately.

Choose TP-Link Archer BE400 if

  • The two listed bands meet your network plan and 6 GHz is not a requirement.
  • You want a dedicated 2.5 Gbps WAN, a separate 2.5 Gbps LAN, and three 1 Gbps LAN ports.
When the recommendation changes
  • Recheck the choice if your client devices, internet gateway, switch, wired equipment, or desired WAN/LAN assignment changes; published port labels alone do not establish real-world throughput or Wi-Fi results.

The differences that matter

Band Layout And 6ghz Client Fit

ASUS RT-BE9700

ASUS lists operating frequencies of 2.4, 5, and 6 GHz for RT-BE9700.[1]

TP-Link Archer BE400

TP-Link describes Archer BE400 as dual-band and lists 5 GHz and 2.4 GHz bands.[2]

What this changes: A 6 GHz band matters only when the buyer has compatible clients and a concrete use for it; specifications alone do not establish performance.[1, 2]

The better fit depends on your priorities

Wired Port Mix And Multigig Topology

ASUS RT-BE9700

ASUS lists one 10 Gbps WAN/LAN port, one 2.5 Gbps WAN/LAN port, and three 2.5 Gbps LAN ports for RT-BE9700.[1]

TP-Link Archer BE400

TP-Link lists one 2.5 Gbps WAN port, one 2.5 Gbps LAN port, and three 1 Gbps LAN ports for Archer BE400.[2]

What this changes: Buyers should map their gateway and wired devices to physical port roles. ASUS's WAN/LAN labels refer to combo-role ports, not separate simultaneous ports; neither list demonstrates actual connection speed.[1, 2]

The better fit depends on your priorities

Best for your routine

You have compatible 6 GHz clients and specifically want a router with a third listed band.

Best fit: ASUS RT-BE9700

Based on listed features, not comparative testing.

The RT-BE9700's published specification lists 6 GHz alongside 2.4 and 5 GHz; this is a configuration match, not a prediction of faster service or greater coverage.

You want a dedicated 2.5 Gbps WAN and three separate 1 Gbps LAN ports, and the dual-band listing fits your plan.

Best fit: TP-Link Archer BE400

Based on listed features, not comparative testing.

The Archer BE400's listed port arrangement directly matches that wiring requirement; this does not establish throughput or superiority in another topology.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare current offers against your need for 6 GHz and the ASUS wired port roles. Check which band and port layout fits your network before deciding whether any price difference matters.

Compare current offers; this article does not assess whether now is a better time to buy.

Limitations

  • This comparison uses published manufacturer configurations and does not include hands-on testing or a controlled side-by-side measurement.
  • Client compatibility, local radio conditions, internet service, gateway settings, and network topology affect the usefulness of each configuration. Check the exact requirements of your devices and service before buying.
  • No current offer terms or price-history analysis is included.

Questions shoppers ask

Does the Archer BE400 include a 6 GHz band?

TP-Link describes the Archer BE400 as dual-band and lists its 5 GHz and 2.4 GHz bands. The RT-BE9700's ASUS specification lists 6 GHz as a third band. This comparison does not assess how either will perform in your home.

How should I count the ASUS WAN/LAN ports?

ASUS lists one 10 Gbps WAN/LAN port and one 2.5 Gbps WAN/LAN port, in addition to three 2.5 Gbps LAN ports. Each WAN/LAN port is a single physical port with a selectable role, so plan which one will connect to your gateway and which roles your remaining devices need.

Which router is faster?

These manufacturer specifications do not establish which router will be faster in a particular home. This article compares listed bands and port roles; real results depend on devices, configuration, internet service, and local conditions.

Methodology and sources

Compared the ASUS RT-BE9700 and TP-Link Archer BE400 using each manufacturer’s US source for band layout and wired port roles. No independent performance measurements were used.

AI assistance organized the published specifications into conditional configuration choices; no physical testing was performed.
