The Deco BE77 is a genuine step up in raw wireless capability: a tri-band Wi-Fi 7 mesh system with a 6 GHz band, ten internal antennas, a 10G combo port on every unit and a built-in speed test, none of which the dual-band RT-BE86U can offer. The RT-BE86U counters with standalone router depth of its own, a 10G port, a command line interface and AsusWRT's full toolkit, all backed by a 3-year warranty against the Deco's two years. Buy the Asus RT-BE86U for an affordable single router with a 10G port and a longer warranty, or the TP-Link Deco BE77 if you need 6 GHz mesh coverage across a large, multi-node home.
