Lab Setup and Throughput Testing

We tested the Archer AX21 in a 2,000 sq ft home lab with 50+ devices, using iPerf3 for close-range (5ft), medium (30ft), and long-range (50ft + walls) throughput on both bands. Peak 5GHz speeds hit 900Mbps download, compared against baselines from Intel WiFi 6 adapters.

Real-World Scenarios

Multi-device stress tests simulated streaming (4K Netflix), gaming (low latency ping <20ms), and IoT loads (20 smart bulbs + cameras). Signal strength measured via Ekahau Sidekick heatmaps, coverage verified at -67dBm threshold. Firmware stability checked over 72 hours with 24/7 uptime.

Competitor Benchmarks

Cross-tested against Netgear RAX10 and Asus RT-AX55 using same methodology; included app setup time, heat under load (max 45°C), and power draw (8W idle).
