X app shows devices connected, but they really are not. Cannot get connected

Hi, I have a gateway and two X1 pods.  Xfinity app shows strong connections between pods and gateway.  App also shows multiple devices (iPad, iPhone, MacBook) are connected to one of the pods, but the devices are NOT connected to Wi-Fi (no Wi-Fi symbol on devices, no internet access).  When using troubleshooting on app, no issues detected.  Restart modem does not fix connection.

The only connections that work are those made to the gateway.  These connections are also lost intermittently.  Restart modem works for a day or two, then connections drop again.  Again, troubleshooter does not detect any issues.

Any recommendations?  Thank you.
