It appears my orbi router is not getting a DNS address from comcast. So it seems there is a communication problem from my modem to my router. I called xfnity...they told me to call netgear who told me to call xfinity.....

A couple things.
1. make sure that only the orbi is connected to the cm1100. It might have more than 1 port but xfnity only supports 1 connected device. If you had more than 1 connected, power everything off, power the modem on and give it a couple minutes to boot, then power on the orbi connected to port 1 and give it a couple minutes.
2. Try a different DNS Server. Here's a few. Also remember to change the ipv6 dns server if ipv6 is enabled.
