Xfinity pods went offline and won’t come back on

I have tried to troubleshoot all 6 pods several times. I have unplugged and rebooted my router and unplugged all pods, waited and slowly replugged all pods back in about an hour ago and none of my 6 pods will still not connect.  I am at my wits end! All 6 are still showing offline. How do I get them to reconnect? Do I have to disconnect/remove each pod from my system, then add each one back on as if they are brand new pods, to get them to reconnect to WiFi? I'm afraid that will cause more problems, but any guidance and help is greatly appreciated!
