TP-Link Deco XE75
Best for budget-conscious buyers, TP-Link ecosystem users, and homes under 3,000 sq ft wanting intuitive controls and solid WiFi 6E performance.
Performance & Speed Comparison
Peak Throughput
XT9 achieves up to 6 Gbps vs XE75's 5.4 Gbps; both excellent for WiFi 6E, but XT9 edges ahead with better multi-device real-world throughput.
Coverage Range
XT9 covers ~2,600 sq ft per unit versus XE75's ~2,000 sq ft; XT9's larger per-unit range reduces total units needed for very large homes.
Wired Backhaul/Ports
XT9 features dual 2.5 Gbps ports enabling faster wired backhaul; XE75 limited to single 1 Gbps port, bottlenecking fiber/10G connections.
Gaming Optimization
XT9's Broadcom processors and QoS tuning prioritize low-latency gaming; XE75 solid but not explicitly optimized for competitive gaming workloads.
Smart Home Integration
XE75 integrates seamlessly with TP-Link Kasa ecosystem; XT9 lacks native smart home device management despite ASUS's larger portfolio.
Ease of Setup & UI
TP-Link's mobile app is cleaner and more intuitive with better granular controls; ASUS app functional but less polished.
