The main trade-off
ASUS documents Wi-Fi 7 MLO, a 2.5G role-configurable Ethernet port and USB mobile tethering; TP-Link documents Wi-Fi 6 and four dedicated Gigabit LAN ports. The fit depends on client readiness and the home’s connection plan, not on a measured speed result.
Quick verdict
Choose ASUS RT-BE58U for a documented Wi-Fi 7 MLO path with compatible clients or a 2.5G WAN/LAN port that can be configured for the required role. Its USB 4G/5G tethering feature is documented, but the reviewed AX21 V5 materials do not settle whether it offers a comparable path; confirm that before treating it as a deciding difference. Choose Archer AX21 V5 if Wi-Fi 6 is enough and its fixed Gigabit WAN plus four Gigabit LAN ports fit your wiring plan. Neither router has a measured coverage or throughput win established here.
Choose ASUS RT-BE58U if
- You will connect Wi-Fi 7 clients and want to use MLO across the RT-BE58U’s 2.4 and 5 GHz bands, checking each client’s supported mode.
- Your wired plan calls for a 2.5G connection configurable as WAN or LAN. If USB cellular backup is a requirement, ASUS documents a tethering path; confirm AX21 support with TP-Link before ruling it out.
Choose TP-Link Archer AX21 V5 if
- Your plan is centered on a fixed Gigabit WAN and four dedicated Gigabit LAN ports, and Wi-Fi 6 meets your requirements.
- You are not buying for Wi-Fi 7 MLO; older devices can still connect normally to a Wi-Fi 7 router, but they will not use MLO on the ASUS.
When the recommendation changes
- If your intended devices do not support Wi-Fi 7, they will not use MLO on the ASUS.
- If you need 6 GHz Wi-Fi, neither exact model is documented as a 6 GHz router in the reviewed U.S. specifications.
- If cellular tethering is essential, verify the intended modem/carrier with ASUS and ask TP-Link whether the AX21 V5 supports your setup before choosing on that basis.
The differences that matter
| Decision point | ASUS RT-BE58U | TP-Link Archer AX21 V5 |
|---|---|---|
| Wireless Generation And Client Readiness | RT-BE58U is a dual-band Wi-Fi 7 router operating on 2.4 and 5 GHz; ASUS describes MLO across those bands, with supported modes and bands varying by client device.[1, 2] | The selected Archer AX21 V5 is a dual-band Wi-Fi 6 router. MLO requires Wi-Fi 7 support on both router and client, so this Wi-Fi 6 model is not the router choice for an MLO setup.[3, 5, 6] |
What this changes: The ASUS is the documented fit for a buyer who specifically wants router-side Wi-Fi 7 MLO and already has, or plans to buy, compatible Wi-Fi 7 clients. If those clients are absent, the MLO feature does not apply to them; this does not establish a real-world speed or coverage advantage.[1, 6] The better fit depends on your priorities | ||
| Wired Port Topology And Internet Fallback | RT-BE58U has one 2.5G WAN/LAN port, one 1G WAN/LAN port and three 1G LAN ports; the two WAN/LAN ports have flexible roles.[2] | Archer AX21 V5 has one fixed Gigabit WAN port and four Gigabit LAN ports.[3, 5] |
What this changes: Choose by the connection map: ASUS lists a multi-gig port that can serve WAN or LAN plus a second role-configurable port; TP-Link lists four dedicated Gigabit LAN ports alongside its Gigabit WAN. Neither published port list demonstrates faster real-world internet service.[2, 5] The better fit depends on your priorities | ||
| Wired Port Topology And Internet Fallback | ASUS documents USB 4G/5G mobile tethering and Auto Mobile Tethering for RT-BE58U; supported modem and carrier compatibility should be checked for the intended setup.[1, 2] | Unknown: the reviewed AX21 V5 U.S. product/support materials establish its Ethernet port layout but do not settle whether it supports a comparable cellular tethering setup.[3, 4, 5] |
What this changes: If USB cellular fallback is a requirement, ASUS has a documented setup path; the reviewed AX21 materials do not prove that AX21 lacks one, so confirm with TP-Link before treating it as a deciding difference.[1, 4, 5] The better fit depends on your priorities | ||
Best for your routine
A buyer with Wi-Fi 7 client devices that support an ASUS-listed MLO mode wants a router feature that can use the 2.4/5 GHz bands together.
Best fit: ASUS RT-BE58U
Based on listed features, not comparative testing.
The RT-BE58U is documented as Wi-Fi 7 with dual-band MLO. Confirm the client’s supported MLO mode; no measured speed or latency result is implied.
A buyer whose plan is a fixed Gigabit WAN plus four dedicated Gigabit LAN connections, and who does not need Wi-Fi 7 MLO, prefers the documented AX21 V5 port arrangement.
Best fit: TP-Link Archer AX21 V5
Based on listed features, not comparative testing.
TP-Link lists one dedicated Gigabit WAN and four dedicated Gigabit LAN ports for AX21 V5. ASUS instead lists two role-flexible ports and three fixed Gigabit LAN ports; this is a layout preference, not a speed result.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
A higher live price would need to match a buyer’s actual need for compatible-client Wi-Fi 7/MLO or 2.5G port-role flexibility. ASUS also documents USB tethering, but the checked AX21 sources leave its equivalent capability unknown; confirm it before treating it as a reason to pay more. No stable price premium is stated here.
No comparable current offer or price-history window was assessed, so this comparison cannot support a Buy Now or Wait recommendation.
Limitations
- RT-BE58U’s reviewed U.S. specifications list only 2.4 and 5 GHz bands; Wi-Fi 7 does not mean this exact router has 6 GHz.
- MLO requires Wi-Fi 7 support on both router and client, and ASUS says supported modes and bands vary by device.
- The TP-Link product page identifies the selected AX21 V5 family; its support site distinguishes regional hardware revisions. Check the label on the unit if you need to confirm the exact revision before applying V5.6/V5.60 documents.
- ASUS documents USB 4G/5G tethering. The reviewed AX21 V5 sources do not settle whether comparable cellular tethering is supported; this is unknown, not evidence that it is absent.
- No controlled throughput, latency or coverage testing was performed. Manufacturer rate labels and feature descriptions do not establish real-world results.
- No comparable current-price assessment or longer price-history window is included.
Questions shoppers ask
Does the RT-BE58U include a 6 GHz band?
The reviewed ASUS U.S. specification lists 2.4 GHz and 5 GHz operating frequencies for this exact model. Do not assume a 6 GHz radio from its Wi-Fi 7 label.
Will older Wi-Fi devices use MLO on the ASUS?
No. TP-Link’s MLO guide says both router and client need Wi-Fi 7 for MLO. Older devices can connect normally, but they will not use MLO; ASUS also notes client-supported modes and bands vary.
Can I use the AX21 V5 for USB cellular backup?
The reviewed AX21 V5 pages establish Ethernet ports but do not settle this. Confirm the exact feature with TP-Link before purchase if cellular tethering is essential. ASUS lists USB 4G/5G mobile tethering, subject to compatible equipment and setup.
Methodology and sources
Compared published wireless standards and client requirements, then compared Ethernet port roles and documented mobile-tethering setup. No throughput, latency or coverage tests were performed.
