TP-Link Archer BE400 vs Archer AX55: Which Router Fits Your Clients and Wired Setup?

Match Wi-Fi features and wired link rates to your clients and network. BE400 adds documented Wi-Fi 7/MLO and 2.5 Gbps WAN/LAN links alongside three 1 Gbps LAN ports. AX55 lists Wi-Fi 6, a Gigabit WAN and four Gigabit LAN ports. Both have four LAN jacks; advertised wireless rates do not predict your internet speed.

The buying question

Will your clients use the BE400’s documented Wi-Fi 7 features and will your wired setup use its 2.5 Gbps WAN/LAN links, or do the AX55’s Wi-Fi 6 features and Gigabit links fit your plan?

BE400 documents dual-band Wi-Fi 7/MLO and one 2.5 Gbps WAN plus one 2.5 Gbps LAN and three 1 Gbps LAN ports. AX55 documents dual-band Wi-Fi 6 and one Gigabit WAN plus four Gigabit LAN ports. Both have four LAN jacks; choose by whether a 2.5 Gbps wired link and compatible client features matter, not by LAN-jack count.

Quick verdict

Choose TP-Link Archer BE400 if

  • You have Wi-Fi 7 clients that support the relevant feature and want BE400’s documented MLO option.
  • Your service and modem support multi-gig and you want to connect a 2.5 Gbps wired endpoint through its 2.5 Gbps LAN port.

Choose TP-Link Archer AX55 if

  • AX55’s Wi-Fi 6 feature set matches your clients and your planned WAN/LAN links are Gigabit or slower.
  • You do not need a 2.5 Gbps wired link; the BE400’s additional link-rate capability would not serve your current plan.

When the recommendation changes
  • If your clients do not support Wi-Fi 7/MLO, BE400's Wi-Fi 7-specific features do not establish a benefit for those clients.
  • If your ISP plan, modem, cable or wired devices are limited to Gigabit, the BE400’s 2.5 Gbps capacity may go unused; the number of LAN jacks is four on each router.
  • If you need more than four wired LAN connections, plan a separate switch and verify its uplink and speed fit your devices.

The differences that matter

Wireless Client Band Workflow

TP-Link Archer BE400

U.S. Archer BE400 product page identifies dual-band Wi-Fi 7 (802.11be), MLO for Wi-Fi 7 clients, and required corresponding client support.[1]

TP-Link Archer AX55

U.S. Archer AX55 product page identifies dual-band Wi-Fi 6 (802.11ax), HE160 on 5 GHz, OFDMA and required corresponding client support.[3]

What this changes: Choose by whether your clients support the router features you want; feature descriptions do not establish a measured winner.[1, 3]

The better fit depends on your priorities

Wired Port Backhaul Workflow

TP-Link Archer BE400

BE400 U.S. model page lists 1×2.5 Gbps WAN, 1×2.5 Gbps LAN and 3×1 Gbps LAN ports.[1]

TP-Link Archer AX55

AX55 U.S. model page lists 1×1 Gbps WAN and 4×1 Gbps LAN ports.[3]

What this changes: BE400 provides a 2.5 Gbps WAN and a 2.5 Gbps LAN for a multi-gig service path or wired endpoint, plus three 1 Gbps LAN ports. AX55 provides a Gigabit WAN and four Gigabit LAN ports. Both list four LAN jacks, so choose by the link rates your modem, ISP, endpoint and cabling can use; port count alone does not distinguish them. Neither specification proves actual network speed.[1, 3]

The better fit depends on your priorities

Best for your routine

A home adding a Wi-Fi 7 client that supports the relevant BE400 feature and wants its documented MLO path.

Best fit: TP-Link Archer BE400

Based on listed features, not comparative testing.

BE400 documents MLO for Wi-Fi 7 clients; this is feature fit, not a tested speed or coverage result.

View TP-Link Archer BE400 on AmazonPaid link

A home with Wi-Fi 6 clients and planned WAN/LAN links at Gigabit or slower, without a current need for 2.5 Gbps.

The better fit depends on your priorities

Both router layouts may fit this requirement: AX55 lists Gigabit WAN/LAN, while BE400 also provides three 1 Gbps LAN ports alongside its 2.5 Gbps WAN/LAN ports. AX55 is a feature-fit option when its Wi-Fi 6 and Gigabit specifications meet the plan; this comparison does not establish better value or performance.

Value and trade-offs

The offers shown are per listed package; check the quantities and current terms on Amazon before comparing totals.

A higher live checkout price should be justified by features your clients, service and wired devices can use; no fixed-price value conclusion is made.

Compare current checkout prices and offer terms; price observations do not include enough history to assess purchase timing.

Limitations

  • The exact hardware revision tied to each retail ASIN is not established here. Check the unit label and matching U.S. support page before using revision-specific firmware or mesh instructions.
  • Product-page Wi-Fi rates are specification rates, not measured internet speed, coverage or a head-to-head result. Client support, radio conditions, building layout, ISP service, modem and cable affect actual results.
  • No cross-model EasyMesh compatibility conclusion is made from the mixed-model discussion lead; confirm both exact hardware revisions and firmware with TP-Link before planning a mesh pairing.

Questions shoppers ask

Will Wi-Fi 7 or the advertised rates automatically make my internet faster?

No. TP-Link requires client support for the corresponding Wi-Fi 7 features and says actual throughput varies with network conditions, client limits, location, obstacles and other factors. Your service and wired path also matter.

Can BE400 use multi-gig internet?

Its U.S. page lists one 2.5 Gbps WAN and one 2.5 Gbps LAN. Compatible service, modem, cable and LAN-side device are needed to use a multi-gig path.

Can I assume these retail units work together in EasyMesh?

This comparison does not establish cross-model compatibility for the exact retail units. Check both hardware labels and TP-Link's matching U.S. support information first.

Methodology and sources

Compared U.S. Archer BE400 and AX55 product-page descriptions for client wireless features and Ethernet port layouts. Used U.S. support pages only to bound revision certainty; did not infer cross-model mesh behavior, throughput, coverage or latency.

Automation organized manufacturer specifications into this comparison; product statements are tied to cited TP-Link sources.
