You should be able to tell immediately by consulting the Settings menu whether or not your device is properly linked.

  • If Netflix does not load on Xfinity, clear the app, reset your network, double-check that you are connected to a network.

Do not unplug the router from its power source and then reconnect it. Instead, you’ll want to use the Xfinity app to restart. This will ensure the Xfinity box will be reset properly rather than a quick plug pull.

It may be that an Xfinity remote factory reset will help with the overall connection as a whole, including slow apps:
