What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
ASUS RT-AX88U Pro
Across 2 testing outlets, the Asus RT-AX88U Pro lands as a strong, well-rounded Wi-Fi 6 router. XDA Developers measured consistent throughput (roughly 680-830Mbps down in living-room testing, holding up well across garage and bedroom locations) and called it one of the best all-around Wi-Fi 6 routers with multi-gig support. Dong Knows Tech backed this up with an 8.8/10 rating, over 2000Mbps sustained Multi-Gig LAN throughput, and 2500 ft2 of coverage, praising its Wi-Fi, wired, and network storage performance as an excellent buy at its $350 street price. The lone knock, noted only by Dong Knows Tech, is a reduced port count of 6 network ports versus 9 on the previous variant. (2 sourced reviews, 2 lab-tested.)
Praised: Strong, consistent Wi-Fi 6 throughput across multiple rooms/distances; Excellent multi-gig wired and network storage performance; Good overall value / recommended buy.
Flagged: Reduced to only 6 network ports, down from 9 on the previous variant.
