If your Firestick isn't connecting to the internet, it could be due to a few reasons. First, check if you're on the correct Wi-Fi network and that the signal is strong. Sometimes, simply restarting your Firestick and router can resolve the issue. If you're still having trouble, consider forgetting the network in the Firestick settings and reconnecting. Lastly, ensure there are no outages with your internet service provider.
