ASUS RT-AC86U (WiFi 5/Standalone Router/Dual-Band AC2900/Gaming Enthusiast Classic) Review
ASUS RT-AC86U dual-band WiFi 5 gaming router with AC2900 speed, a 1.8GHz processor, AiMesh support, and WTFast game acceleration.
The RT-AC86U became something of an enthusiast classic for its era, praised for a genuinely fast processor that kept it responsive under heavy load long after cheaper WiFi 5 routers started to choke. It predates WiFi 6, but its AiMesh support and strong CPU mean it still holds up as a secondary node or budget gaming router today.
Overview
A dual-band AC2900 router built around a comparatively powerful 1.8GHz dual-core processor, with AiMesh support, WTFast gaming acceleration, and dual USB ports for storage or printer sharing.
Comparison to Alternatives
Against the newer ASUS RT-AX86U Pro, the RT-AC86U lacks WiFi 6 and OFDMA efficiency but shares a similar gaming-focused feature set at a lower price. Compared to the Linksys EA8300 Tri-Band, the AC86U has a stronger processor and better gaming-specific tools despite fewer radio bands. Buyers wanting current WiFi 6 gaming performance should upgrade to the ASUS RT-AX86U Pro instead.
