Verdict
ASUS RT-AC86U
7 / 10 Expert Rating
An aging but still-capable gaming router whose strong processor and AiMesh support keep it relevant well past most WiFi 5 routers' shelf life.
Zyxel Armor Z2
6 / 10 Expert Rating
A dated but still functional tri-band WiFi 5 router, reasonable only for budget replacement of similarly old hardware.
