ASUS RT-AX1800S vs TP-Link Archer AX55: Which Router Fits Your Network?
AX55 lists a higher 5 GHz Wi-Fi 6 link-rate ceiling, but that figure depends on HE160-capable clients and regional availability and is not a real-speed result. If you are extending an existing network, choose by compatible mesh ecosystem first: ASUS lists AiMesh for RT-AX1800S, while TP-Link lists OneMesh and EasyMesh for AX55. Both list one Gigabit WAN port.

The buying question
Should you choose the RT-AX1800S or Archer AX55 for your devices, broadband setup, and plans to expand or manage the home network?
AX55 publishes a higher 5 GHz PHY-rate ceiling that depends on HE160-capable clients and regional availability; the more decisive factor may be which mesh ecosystem and settings route matches equipment already in use.
Quick verdict
Choose ASUS RT-AX1800S if
- Your existing compatible mesh equipment uses ASUS AiMesh, or RT-AX1800S's listed 1,201 Mbps maximum 5 GHz PHY rate over 80 MHz is sufficient for your client mix.
- You want to compare RT-AX1800S's documented AiProtection Classic and client Internet scheduling options with your needs.
Choose TP-Link Archer AX55 if
- Your client supports HE160, 160 MHz is available in your region, and you want AX55's higher published maximum 5 GHz link rate.
- You already own compatible TP-Link OneMesh/EasyMesh devices, or want to consider AX55's Tether app/web management and HomeShield plan options.
When the recommendation changes
- A client supports 160 MHz and that bandwidth is available in the buyer's region, making AX55's HE160 specification relevant.
- An existing compatible AiMesh or TP-Link mesh setup outweighs the advertised radio-rate difference.
- A multi-gig Ethernet WAN is required; neither model's listed Gigabit WAN meets that requirement.
The differences that matter
Client And Broadband Fit
ASUS RT-AX1800S
Wi-Fi 6, 2x2; up to 1,201 Mbps at 5 GHz and 574 Mbps at 2.4 GHz; 80 MHz bandwidth[1]
TP-Link Archer AX55
Wi-Fi 6; up to 2,402 Mbps at 5 GHz with HE160 and 574 Mbps at 2.4 GHz[3]
What this changes: The listed higher AX55 5 GHz link-rate ceiling depends on a compatible client and regional availability; neither specification predicts real-world throughput. Both products list one Gigabit WAN and four Gigabit LAN ports.[1, 3]
Management And Expansion Workflow
ASUS RT-AX1800S
RT-AX1800S is listed for AiMesh primary-router and node modes[1]
TP-Link Archer AX55
Archer AX55 supports OneMesh and EasyMesh with compatible devices[3]
What this changes: Choose the ecosystem compatible with equipment already owned and verify the exact node or extender model; no cross-brand interoperability is established.[1, 3]
Management And Expansion Workflow
ASUS RT-AX1800S
AiProtection Classic and per-client Internet time scheduling are documented for RT-AX1800S[1, 2]
TP-Link Archer AX55
AX55 lists Tether app/web management and HomeShield free Basic/paid Pro plan structure[3]
What this changes: Use these as a checklist of documented workflows and terms rather than a measure of relative security or control effectiveness.[1, 2, 3]
Best for your routine
Adding to an existing ASUS AiMesh network
Best fit: ASUS RT-AX1800S
Based on listed features, not comparative testing.
Choose RT-AX1800S when the existing compatible nodes use AiMesh; verify the exact device match before buying.
Adding to a compatible TP-Link OneMesh or EasyMesh network
Best fit: TP-Link Archer AX55
Based on listed features, not comparative testing.
Choose Archer AX55 when the existing compatible equipment uses OneMesh or EasyMesh; verify the exact device match before buying.
Using clients that support HE160 where 160 MHz is available
Best fit: TP-Link Archer AX55
Based on listed features, not comparative testing.
AX55 lists a higher 5 GHz PHY-rate maximum under HE160, but the rate is not a measured speed result.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Compare current offers after confirming the router model and any mesh accessories needed; a higher offer would need to be justified by a client capability or network ecosystem you will use.
Price evidence is current-only. Compare current offers when ready to buy; this snapshot does not support historical-low or purchase-timing advice.
Limitations
- Published Mbps figures are Wi-Fi link-rate specifications, not measured internet speeds or a comparative coverage result. Actual performance depends on clients, ISP, building, traffic and other conditions.
- TP-Link lists multiple Archer AX55 hardware revisions and says version availability varies by region. Check the hardware version printed on the router before selecting firmware or an extender, and use the local support page.
- Mesh compatibility is model- and ecosystem-specific. Confirm the precise node or extender before purchase; neither source establishes ASUS AiMesh and TP-Link mesh interoperability.
- Both manufacturer pages list one Gigabit WAN and four Gigabit LAN ports. Buyers requiring multi-gig wired WAN should look for a router with a matching port.
- No comparable independent test was used to establish throughput, coverage, latency, reliability or security superiority.
- Offers and included accessories can change; check the selected offer and package contents at checkout.
Questions shoppers ask
Will the Archer AX55 deliver 2,402 Mbps internet speed?
That real-world result is not established here. TP-Link lists 2,402 Mbps as a maximum 5 GHz Wi-Fi 6 PHY rate with HE160; compatible clients and regional availability are required, and actual network throughput varies.
Can I add either router to the mesh system I already own?
Check the system name and exact-device compatibility list first. ASUS lists RT-AX1800S for AiMesh, while TP-Link lists OneMesh and EasyMesh support for Archer AX55 with compatible devices; these pages do not establish cross-brand operation.
Do the listed ports support a multi-gig internet plan?
Each page lists a single Gigabit WAN port. This comparison does not identify a multi-gig WAN port on either model.
Methodology and sources
I compared the manufacturers' stated Wi-Fi rates, wired-port listings, mesh compatibility descriptions, management options and relevant setup guidance. These sources support feature-fit advice only; they do not provide a controlled test of the two routers.
