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.
Tenda AX12
6.3 / 10 Expert Rating
A genuinely serviceable rock-bottom WiFi 6 router for secondary spaces, with thinner software support than the major brands.
