I've had the same issue since I first tried to set it up. Just doesn't work.
Nobody seems to have an answer for us.

Can you try pressing the WPS button on the bottom on the box? This should try and connect your device to a wifi signal. Are you using a comcast leased modem or do you own your modem?

I have the same issues. Mine worked for a month and just quit working. I called 1-800 Xfinity but they couldn't fix it. Seems these things are garbage and comcast doesn't want to fix it.
I have a ROKU and it works fine. If I can't get the issue fixed or a new box then Comcast I will just go back to just having Internet.

I had the same issue, where when I plugged the flex box into my android smart TV. One day it just showed a black screen. But then I realized the issue wasn’t the box, it was the TV. I rebooted the TV and it worked, it seems like the flex box is just fine, it’s just the TV’s fault. I don’t know if it helps.
