GoKawiilExplainer: How dual-band and tri-band routers differ in bandwidth and cost
Router shoppers often encounter confusing labels like dual-band and tri-band alongside terms such as Wi-Fi 6E, Wi-Fi 7, and 6GHz. Dual-band routers broadcast on 2.4GHz and 5GHz, while tri-band routers add a third channel, either a second 5GHz band or, in newer Wi-Fi 6E and Wi-Fi 7 models, a dedicated 6GHz band. This extra band gives tri-band routers more overall bandwidth than dual-band alternatives.
