The Nighthawk CAX30 is certified for plans up to 1 Gbps, giving you headroom for future upgrades. If you’re comparing brands, our review of best ASUS WiFi 6 routers highlights similar speed capabilities. For the latest WiFi 7 technology, see Best ASUS WiFi 7 Routers.
WiFi 6 Coverage for the Whole Home
WiFi 6 (AX2700) delivers faster speeds, lower latency, and better handling of multiple devices. The CAX30 covers up to 2,000 square feet and supports 25+ connected gadgets. For larger homes, consider a mesh system; see our guide on best ASUS routers for AiMesh for seamless whole-home coverage.
