Band steering
A WiFi feature where the access point steers clients to the most suitable frequency band (2.4 / 5 / 6 GHz) instead of letting the device choose itself. Goal: get capable devices onto the faster, less congested 5/6 GHz and leave 2.4 GHz for long-range/legacy devices.
Problem: many devices "cling" to 2.4 GHz (longer range, but slow and interference-prone) even when 5 GHz would be better. Band steering "nudges" the client — e.g. by delaying/refusing responses on 2.4 GHz so the device tries 5 GHz. Often paired with the same SSID on all bands (so the user sees no difference). Trade-off: aggressive steering can give a poor experience for devices with weak 5 GHz reception (they should have stayed on 2.4). Related: 802.11k/v/r help clients roam between access points. A standard feature in mesh systems and enterprise WiFi to balance load across bands.
