How do I reactivate my Xfinity Flex box(s) after updating my Xfinity modem?

I was prompted to change my Xfinity password. I did that and of course I couldn't get email on my Mac. I entered the new password and could again get email. However, despite having the right box checked in security settings( allowing 3rd party access); I can not get Comcast email on my iPhone or my

After 11 months using an Arris Surfboard G34 Modem without any problems, in December 2023 we started experiencing disconnections 3 or 4 times a day. The disconnection durations can last up to 10 minutes, after which connection is restored without having to restart the modem. These frequent disconnec

I have had countless issues with my Wi-Fi connection and today my internet randomly shut off and never reconnected.

The Xfi pause feature is useless, I had already set up a schedule for devices to disable their access to the internet yet the devices are still able to access the internet, just ran a test earlier but it seems the only way to pause the devices is the "forget" the devices and reconnect them then the

I feel like an idiot, but can anyone help me use the parental controls via the router? I log into the router. I navigate to parental controls. I enable managed sites.
