Xfinity Flex keeps disconnecting from WiFI
I've only had the Xfinity service for about two months and just started using the Flex boce a couple weeks ago. Everything was working great, but now two days in a row the Xfinity Flex box has disconnected from the WiFi. The Flex box is right next to to WiFi box, so this shouldn't be happening. When I unplug and replug the flex box it reconnects, but I shouldn't have to do that everyday.
Why is this happening and how do I fix it without an HDMI cable?
