TP-Link Archer BE400 vs ASUS RT-BE58U: Which Wi-Fi 7 Router Fits Your Network?
Pick the Archer BE400 when your wired layout needs a dedicated 2.5G internet port and a separate 2.5G LAN jack. Pick the RT-BE58U when USB mobile tethering, Dual WAN or compatibility with an existing ASUS AiMesh network matters more. Both are dual-band Wi-Fi 7 models without 6 GHz; BE400’s higher advertised rate is not proof of better real-world speed or range.

The buying question
Which model better fits the buyer’s port layout and network-extension needs, and what does the higher advertised Wi-Fi rate actually tell them?
BE400 provides dedicated 2.5G WAN and LAN ports and a higher advertised wireless class; RT-BE58U offers a flexible 2.5G WAN/LAN jack plus documented dual-WAN and USB mobile tethering. Both are dual-band and use their own mesh ecosystems.
Quick verdict
Choose TP-Link Archer BE400 BE6500 Dual-Band Wi-Fi 7 Router if
- You have multi-gig internet and want to connect a 2.5G wired PC or NAS at the same time without reassigning a shared port.
- You value the BE400’s higher published rate ceiling as a specification, not as a verified real-world speed advantage.
Choose ASUS RT-BE58U BE3600 Dual-Band Wi-Fi 7 Router if
- You want ASUS’s documented Dual WAN or USB 4G/5G mobile-tether backup.
- Your current mesh nodes are compatible ASUS AiMesh devices.
When the recommendation changes
- If 6 GHz is required, neither matches that requirement.
- If real-world speed or range is the deciding factor, these sources do not provide a matched test; do not choose based on advertised class or incomparable review scores.
- If an existing mesh system is already installed, choose according to confirmed EasyMesh or AiMesh compatibility.
The differences that matter
Wireless Bands And Advertised Class
TP-Link Archer BE400 BE6500 Dual-Band Wi-Fi 7 Router
Dual-band Wi-Fi 7 on 2.4 and 5 GHz, with published 5 GHz up to 5,764 Mbps and 2.4 GHz up to 688 Mbps (BE6500/6.5 Gbps class); no 6 GHz band is listed.[1]
What this changes: Both omit 6 GHz. BE400 has the higher manufacturer-rated aggregate PHY class, but that is not a household throughput result; choose only if the higher published 5 GHz ceiling fits your device/network needs, and do not treat it as proof of faster real-world service.[1, 2, 3]
Wired Ports And WAN Assignment
TP-Link Archer BE400 BE6500 Dual-Band Wi-Fi 7 Router
One dedicated 2.5 Gbps WAN, one dedicated 2.5 Gbps LAN, and three 1 Gbps LAN ports.[1]
ASUS RT-BE58U BE3600 Dual-Band Wi-Fi 7 Router
One 2.5 Gbps WAN/LAN port, one 1 Gbps WAN/LAN port, and three 1 Gbps LAN ports. The 2.5 Gbps jack has a shared WAN/LAN role.[3]
What this changes: For >1 Gbps internet plus a wired 2.5 Gbps PC/NAS at the same time, BE400 has a dedicated port for each role. ASUS can assign its 2.5G jack to either WAN or LAN; if using it for >1G WAN, it does not leave a separate 2.5G LAN jack.[1, 3]
Mesh Ecosystem Fit
TP-Link Archer BE400 BE6500 Dual-Band Wi-Fi 7 Router
EasyMesh-compatible with compatible EasyMesh routers and extenders.[1]
What this changes: If you already own compatible nodes, matching the router to that brand/system can avoid replacing them; EasyMesh and AiMesh are different ecosystems and cross-compatibility is not established by these sources. Neither router has a universal mesh advantage.[1, 2]
WAN Backup And USB Role
TP-Link Archer BE400 BE6500 Dual-Band Wi-Fi 7 Router
TP-Link lists USB 3.0 storage functions (FTP, media and Samba server) for BE400, but its published specifications do not confirm mobile tethering or dual-WAN support.[1]
ASUS RT-BE58U BE3600 Dual-Band Wi-Fi 7 Router
The US RT-BE58U tech spec lists Dual WAN, 3G/4G LTE dongle support and 4G/5G auto mobile tethering through USB.[3]
What this changes: For cellular backup or dual-WAN, ASUS is the documented fit. TP-Link lists USB storage uses, but its published specifications do not confirm WAN-backup support; that does not establish that the feature is unavailable.[1, 3]
Measured Speed And Range
TP-Link Archer BE400 BE6500 Dual-Band Wi-Fi 7 Router
RTINGS independently tested the Archer BE400; some numerical results are available only to members.[4]
ASUS RT-BE58U BE3600 Dual-Band Wi-Fi 7 Router
TechGearLab’s RT-BE58U review includes throughput and range testing under its own test setup.[5]
What this changes: These independent reviews use different test setups and do not test both routers side by side, so they cannot establish which model is faster or reaches farther under the same conditions.[4, 5]
Best for your routine
More than 1 Gbps internet plus a 2.5G wired PC or NAS connected simultaneously
Best fit: TP-Link Archer BE400 BE6500 Dual-Band Wi-Fi 7 Router
Based on listed features, not comparative testing.
BE400 documents dedicated 2.5G WAN and 2.5G LAN ports. ASUS has one 2.5G WAN/LAN port, so it cannot fill both roles with 2.5G at once.
USB cellular backup or dual-WAN setup
Best fit: ASUS RT-BE58U BE3600 Dual-Band Wi-Fi 7 Router
Based on listed features, not comparative testing.
ASUS documents Dual WAN and USB 4G/5G tethering. The reviewed BE400 documentation does not confirm equivalent backup-WAN support.
Extend an existing router mesh
The better fit depends on your priorities
The useful choice is the ecosystem already installed: EasyMesh for BE400, AiMesh-compatible ASUS routers for RT-BE58U.
What the evidence cannot decide
- Choose a router based on measured real-world speed or range: The available exact-model reviews do not test both devices in the same controlled comparison.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
If the BE400 costs more when you shop, its dedicated 2.5G WAN-plus-LAN layout is the clearest functional reason to pay more. ASUS’s documented Dual WAN/mobile tethering may be more valuable to buyers who need backup connectivity. Prices can change, so compare both current offers before deciding.
There is not enough price history to recommend buying now or waiting for either product; timing is uncertain.
Limitations
- Both models are dual-band; neither has a 6 GHz radio.
- Advertised Wi-Fi rates are theoretical link-rate classes and do not predict internet speed or matched household throughput.
- The independent reviews do not compare the two routers under one test method.
- ASUS releases firmware by RT-BE58U hardware version; check the unit label before installing an update.
- USB mobile-tether/dual-WAN is documented for ASUS. The reviewed TP-Link specification documents storage functions but does not resolve equivalent WAN-backup support.
Questions shoppers ask
Does the Archer BE400 have 6 GHz Wi-Fi?
No 6 GHz band is listed on the US BE400 specifications. It is a dual-band router using 2.4 and 5 GHz.
Can the RT-BE58U connect a 2.5G internet line and a 2.5G wired computer at the same time?
Its 2.5G jack is shared between WAN and LAN. When used for a greater-than-1-Gbps WAN connection, it does not leave a separate 2.5G LAN port; its remaining LAN ports are rated at 1 Gbps.
Which one has better Wi-Fi range?
The available independent reviews test the models separately, so they do not settle which one has better range under a common test setup.
Methodology and sources
The comparison uses US manufacturer specifications for bands, advertised rates, ports, mesh and WAN backup, plus independent reviews to explain the limits of the available speed and range evidence. Prices are not fixed in the article because offers can change.
