Yes. You need your own Wi-Fi network, specifically 2.4GHz (aka 2G) with its own password. Geeni devices use 2G during setup. Smart devices often work with 2GHz because it offers better range and can penetrate walls and obstacles more effectively than 5GHz. This makes it more reliable for devices that might be placed farther away from the Wi-Fi router or have to connect through multiple walls. Once the setup is complete, you may switch to a different network.
