Asus RT-BE90U vs TP-Link Deco BE63

Full Routers comparison in 2026

Updated August 2026
Data from Amazon and official Asus and TP-Link sites.
2026 verdict
Both cover the same three Wi-Fi bands, 2.4, 5 and 6 GHz, and the Asus RT-BE90U takes this comparison on ownership terms: it costs slightly less than the TP-Link Deco BE63 and carries a 3 year warranty against 2, with a 9.4 Gbps rating from its 5764 Mbps 6 GHz radio and AiMesh support if you later want to add coverage. As a single unit it also gives you full control over settings, guest networks and QoS in a way mesh systems tend to simplify away. The TP-Link Deco BE63 answers with a clearly stronger owner rating and the shape that solves coverage problems: multiple nodes, four 2.5G ports on each, and a 6 GHz band available for backhaul between them, which is what keeps speed up at the far end of a house. Choose the TP-Link Deco BE63 if coverage across a larger or awkward home is the problem, and the Asus RT-BE90U for a cheaper tri-band router with a longer warranty and more direct control.

Which one covers a larger home?

The TP-Link Deco BE63, because it is a mesh with multiple nodes and can use 6 GHz for backhaul. A single Asus RT-BE90U must reach every room from one position, though AiMesh allows expansion later.
