We've put up a straightforward, step-by-step instruction on How to Setup Chromecast, as well as some pointers on how to get the most out of the smart TV device. When Google launched Guest Mode, which allows Chromecast to connect to any Google casting-capable device that isn't connected to the internet through Wi-Fi, things got a lot better. The Chromecast, on the other hand, still requires an internet connection via a host (hotspot, router, or ethernet). Chromecast connects to your TV through HDMI and utilises Wi-Fi to connect and stream content from most networked devices, including smartphones and laptops, as well as pre-installed apps that require internet access. So, what are your options if you don't have access to Wi-Fi? The answer is simple: you create Wi-Fi so that a device may connect to Chromecast and control it or reflect its display from afar.
