Connecting all devices to the 5GHz Wi-Fi band is counterproductive. While 5GHz offers higher throughput, it has shorter range and struggles to penetrate walls, meaning distant or obstructed devices perform better on 2.4GHz. Overloading 5GHz with every device — including smart home gadgets and older hardware — creates congestion and airtime issues that slow down high-priority devices. The recommended approach is to assign devices to bands on a per-device basis based on proximity, bandwidth needs, and device capability. Separating bands into distinct SSIDs avoids band-steering issues. Wi-Fi 6E and Wi-Fi 7 routers with the 6GHz band and MLO offer additional improvements for managing multiple devices.
