Gateway Wireless Network is Intermittent Daily

I have a Gateway that loses its wireless connection randomly, at least once a day. Wired connections are fine, and the Xfinity app never shows any issues. This only happens on devices connected to the WiFi broadcasted by the Gateway. Sometimes it will fix itself, other times I have to reboot the Gateway. When trying to connect to the WiFi while it drops, I can see the network briefly but am unable to connect to it; then I lose the ability to see the network at all. I'd like to get a replacement Gateway or find a solution within network settings.

This has to be an issue with the wireless portion of the Gateway but there is nothing within the Xfinity app, Xfinity Assistant, or support options that allows me to properly navigate this issue and speak to a live representative. The customer service is supremely unhelpful.
