Asus ZenWiFi BT6 vs TP-Link Deco BE77 comparison

Updated August 2026

Data from Amazon and official Asus and TP-Link sites.

2026 verdict

Both are tri-band Wi-Fi 7 mesh nodes with a 6 GHz radio, but the Asus ZenWiFi BT6 is the clear value winner against the TP-Link Deco BE77, coming in cheaper, better rated by owners and covered by a longer warranty. The Deco BE77 answers with meaningfully more hardware: ten internal antennas versus seven, a 10G combo port on every unit against the ZenWiFi BT6's 2.5G ceiling, and a built-in speed test the Asus lacks. The ZenWiFi BT6 still holds its own on software, including WireGuard VPN and Asus's AiMesh standard for expansion. For most homes the Asus ZenWiFi BT6 delivers 6 GHz Wi-Fi 7 mesh at a much friendlier price, while the TP-Link Deco BE77 is worth the premium if you specifically need its stronger antenna array and 10G wired backbone across multiple nodes.
