Hi Doroty, We appreciate your feedback. That’s definitely frustrating, and we can see how requiring a separate network could be inconvenient depending on your home setup. For clarification, the Navigator Robot Vacuum works with typical home Wi‑Fi networks that support both 2.4 GHz and 5 GHz bands. However, the robot itself can only connect to a 2.4 GHz network, and your phone should also be connected to the 2.4 GHz network during setup. Shark robot vacuums are not able to connect directly to 5 GHz networks.
