Roaming is the process of switching from Access Point to another on the
same network/SSID, for instance as one walks around the building with his
computer or other Wi-Fi connected device.
Simple case of roaming, that could be reproduced at home, is switching
between 5G and 2.4G bands on the same network/SSID.
The simple way to force roaming is turn off the band on the router your
device is on.
If you are using OpenWRT with Luci there is Disconnect button on the
Overview page next to the device, pressing Disconnect will force roaming.
