With some wifi devices such as range extenders, you have to manually switch networks whenever you move into a new "zone" of the network. That's because each extender actually emits its own signal, forming its own distinct network--like a hotspot.
With Milo, however, you don't need to worry about ever manually switching between networks as you move around your home or business. Milo creates one unified network, and your device automatically stays connected to the Milo with the best signal, and you never need to worry about switching between multiple networks to maintain a strong connection.
While you are always connected to the same network, your devices should automatically switch to connect to the Milo with the best possible signal as you move around. However, you might find that your device clings to the connection to a certain Milo even if it isn't the best quality connection available. This has to do with the way your device works and is easily solved. You can turn your wifi on and off if needed to force your mobile device to reconnect.
In most cases, it is best to have the Milo wifi network name be different from your existing router's wifi network name. This way you have control over which network a device can connect to. If you have a streaming TV that now gets a good signal from Milo, you don't want it connecting to your existing network. This is only possible if the wifi networks have different names.
