Conventional Wi-Fi is set up with a router and a repeater, and each device has its own SSID. While moving around the house, especially when going up and down stairs, the device often remains connected to the increasingly weaker Wi-Fi signal, leading to deteriorating performance. A roaming Wi-Fi network supports a single SSID that automatically detects the best Wi-Fi signal and connects the device to it, ensuring an uninterrupted online experience and the best Wi-Fi reception, no matter which room you are in.
