2026 verdict
Entry-level mesh against a fuller-featured standalone router, and the TP-Link Deco BE25 still gets the nod over the Asus RT-BE90U on cost and owner rating.
The Deco BE25 is TP-Link's cheapest Wi-Fi 7 mesh node, dual-band without a 6 GHz radio and limited to two 2.5 Gbps ports with no USB port at all, but it is expandable into a larger mesh and praised for an easy app. The RT-BE90U answers with a 6 GHz Wi-Fi 7 radio the Deco BE25 lacks, twice as many physical ports, USB storage sharing, and a longer warranty, a more complete single-router package. Buyers on a tight budget who want an easy, expandable mesh should pick the TP-Link Deco BE25, while anyone who wants 6 GHz Wi-Fi 7, more ports and USB sharing from one router should choose the Asus RT-BE90U instead.
