Asus RT-BE90U vs TP-Link Deco BE77

The Asus RT-BE90U takes the overall verdict, costing less than the TP-Link Deco BE77 and backed by a longer warranty. The Deco BE77 answers with a stronger owner rating and far more mesh-ready hardware for buyers who need multiple nodes.

The RT-BE90U is a single standalone router, while the Deco BE77 is a tri-band mesh system designed to run as two or three units, with a 10 Gbps combo port and ten internal antennas per node versus the RT-BE90U's simpler 2.5 Gbps ports and six external antennas.

Yes, the RT-BE90U supports Asus AiMesh so you can add a second Asus unit later, but it ships and is priced as a single router, unlike the Deco BE77 which is built from the ground up as a multi-node mesh system.

Buyers who want one solid Wi-Fi 7 router for a typical home at a lower cost, with the option to add an AiMesh node down the line if needed.

Owners of large or multi-floor homes who plan to run multiple mesh nodes from day one and want the strongest possible per-node hardware and coverage.
