Every dual-band router sold since 2009 has advertised two radios as a feature. Until WiFi 7, those two radios could not cooperate to serve a single device. Each client connected to one band or the other — not both. Multi-Link Operation, the defining architectural feature of WiFi 7, changes that constraint fundamentally. What Dual-Band Actually Meant Before WiFi 7 A dual-band WiFi 5 or WiFi 6 router presents two separate wireless networks: one on 2.

Three standards, three branding names, one frequently confused consumer. The WiFi Alliance’s decision to number WiFi generations rather than recite IEEE amendment codes simplified marketing without simplifying the technology — and the gap between WiFi 6, WiFi 6E, and WiFi 7 is not a matter of minor iteration. Each represents a genuinely different capability profile, and choosing the wrong one for a deployment, or dismissing an upgrade as unnecessary, costs real performance.
