Updated October 2026
Data from the official Asus and TP-Link sites.
2026 verdict
More bands and more ports do not settle this one: the TP-Link Deco BE23 comes out on top over the Asus RT-BE90U on cost and owner satisfaction, even though the Asus router is the more capable box on paper.

The RT-BE90U covers a 6 GHz band the dual-band Deco BE23 lacks, has twice as many physical ports (four versus two), and adds USB storage sharing that the Deco BE23 skips entirely, plus a longer warranty. What the Deco BE23 brings instead is TP-Link's simple mesh app, an easy path to add more units for larger homes, and a strong track record among owners at a friendlier price. Buyers who want the extra spectrum, wired ports and USB sharing on a standalone router should pick the Asus RT-BE90U, while anyone prioritizing an easy, expandable, budget-friendly mesh setup should go with the TP-Link Deco BE23.
