Xfinity App says internet is offline despite having internet

We recently switched our old tv boxes and modem for new ones. Our new modem is an XB8-T. We had trouble setting it up, but it's currently online, however when we use the Xfinity app it says "your home internet is offline". It's not offline, we have internet (though it is stuttering). I checked the browser Xfinity website and it only shows our old modem's name, and says it's offline. It's as if Xfinity doesn't recognize that we've switched to a new one. If anyone can help, please do.

I'd like to add that there's a second issue involving the internet. Before, with the old modem, gaming was quite simple. There were no issues, no packet loss, and rarely any connection issues. But now after switching to the new XB8-T, there has been significant lag and packet loss. If there is any way to fix this issue plus the xfinity app issue, I'd love any suggestions or help.

Hey there, @user_kh40, thanks for reaching out regarding your new modem. Sorry to hear you are having issues with your connection. We want to ensure that your services are working properly for you. Have you tried any troubleshooting since having the new modem connected? Are you using a separate router?

@XfinityJeniece​ Yes, we've had it for about a week, maybe a little more. During this week, I have tried unplugging it for 30 seconds, making sure all the cables are tightened (but not too tight), everything it says to try. I am not using a seperate router.
