Which devices should use 5GHz Wi‑Fi (and which can stay on 2.4GHz)
The piece explains that a dual-band router can broadcast 2.4GHz (longer range) and 5GHz (faster speeds) and lists which devices benefit from each: connect smartphones, tablets, streaming devices, gaming hardware, and work systems to 5GHz for best performance, while reserving 2.4GHz for smart home gear, guest devices, e-readers, and wearables to avoid congesting the main network. It also notes security risks with smart-home devices and suggests isolating them (via Zigbee/Thread or Z-Wave) for better security.
