X-fi gateway has internet connection but is not broadcasting Wi-Fi.

I woke up this morning, and every device in my home that connects wirelessly was disconnected and my home Wi-Fi network is no longer showing up in the available list of networks on any of my devices. I went through all of the basic troubleshooting that the Xfinity app told me to do and it still tells me that I have no issues. So I plugged my Xbox in with an ethernet cable and the Internet works fine. I just have no Wi-Fi. I’ve reset the Gateway twice and it still hasn’t done anything. Is this a hardware issue?
