Asus RT-BE90U vs Asus ZenWiFi BT6

Strip away the branding: these two share nearly the same tri-band Wi-Fi 7 radio, yet the scoreboard still favors the Asus ZenWiFi BT6, which undercuts the Asus RT-BE90U on price and rating while matching it on warranty length. Both are rated for the same combined Wi-Fi speed across 2.4, 5 and 6 GHz, and both support AiMesh, but the ZenWiFi BT6 is built and sold as a mesh node meant to expand alongside other Asus units, with a compact design and internal antennas, though its LAN ports cap out at Gigabit speeds. The RT-BE90U, positioned as the standalone router, actually wires up faster locally with 2.5 Gbps LAN ports across the board, a real edge for anyone connecting wired devices directly. Buyers planning to grow into a multi-node Asus mesh over time should start with the Asus ZenWiFi BT6, while anyone who wants one router with faster wired LAN ports and no plans to add nodes should pick the Asus RT-BE90U.
