ASUS RT-AX88U Pro (WiFi 6/Standalone Router/Prosumer/Dual 2.5G/AX6000) Review
The RT-AX88U Pro is ASUS's prosumer-focused WiFi 6 router, built around dual 2.5G Ethernet ports and WAN aggregation for buyers with multi-gig internet plans who don't need the gaming-branded ROG lineup.
Two 2.5Gbps ports can be combined via WAN aggregation to exceed standard gigabit throughput on supporting ISP plans, a feature usually reserved for business-class routers.
Dual 2.5G Ports, Aggregated
Two 2.5Gbps ports can be combined via WAN aggregation to exceed standard gigabit throughput on supporting ISP plans, a feature usually reserved for business-class routers.
AiMesh Without the Gaming Markup
Full AiMesh compatibility lets buyers add ASUS mesh nodes later, while the RT-AX88U Pro itself skips the RGB and gaming branding of ASUS's ROG Rapture line for a more straightforward prosumer design.
Comparison to Sibling Products
Against the ASUS ROG Rapture GT6 already on this site, the RT-AX88U Pro trades WiFi 7 and gaming-specific features for dual 2.5G WAN aggregation at a lower price. Against the ASUS RT-AX86U Pro covered in this batch, the AX88U Pro steps up with dual-band-only but higher-tier hardware and business-friendly features like VPN fusion.
