Will my devices automatically switch between 2.4 GHz and 5 GHz Wi-Fi frequencies?
Some devices, such as smartphones and laptops, can automatically switch between 2.4 GHz and 5 GHz Wi-Fi frequencies, depending on the strength of the signal and the level of interference. This feature is known as band steering or frequency handover. However, not all devices support band steering, and the behavior can vary depending on the device and the router being used. In general, devices will tend to prefer the 5 GHz band if it is available, as it typically offers faster speeds and lower interference.
To take advantage of band steering, you need to have a router that supports this feature, as well as devices that are capable of switching between frequency bands. You should also ensure that your router is configured to allow band steering, as this feature may need to be enabled manually. Additionally, you can use features such as Wi-Fi roaming or mesh networking to create a network that allows devices to seamlessly switch between different access points and frequency bands, providing a more robust and reliable connection. By using band steering and other advanced features, you can create a network that automatically optimizes itself for the best performance.
