We recommend that, during your home internet device setup, you establish two completely separate networks for guests and family. Having friends and family over for dinner is always a wonderful and festive event. And, of course, they all want to jump on your internet and surf. However, you probably have no idea where their device has been. And, chances are, they probably don’t have the same layers of security you do. This is the value of having that guest network separate from the home users. For home users, we recommend that you use the following networks if available on your device: Home network: 5 GHz Guest network: 2.4 GHz Dual-band routers provide two independent and dedicated networks, 2.4 GHz and 5 GHz, which allows for flexibility and bandwidth management. If your device only supports 2.4 GHz, you can still safely use the guest network as long as it uses a different password than your home Wi-Fi network. If you don’t have a dual-band router, there are plenty of budget-friendly options on Amazon.
