2026 verdict
The TP-Link Deco X55 takes this router versus mesh matchup on both price and owner rating, matching the TP-Link Archer BE400 on warranty term alone.
The BE400 is a single-unit dual-band Wi-Fi 7 router rated BE6500 with Multi-Link Operation, a 2.5 Gbps WAN port, six external antennas and a USB 3.0 port for network storage, none of which the Deco X55 offers. In exchange, the Deco X55 brings a dual-band Wi-Fi 6 mesh system rated AX3000 that ships as expandable nodes, a built-in speed test, and support for up to 150 connected devices per unit, well above the 90 devices TP-Link rates the BE400 for. Anyone who wants the newer Wi-Fi 7 hardware, faster wired ports or a USB drive attached to the router should pick the BE400; a household that needs to spread reliable coverage across a bigger footprint gets there more cheaply with the Deco X55.
