Hi AdaCats



Thank you for reaching out. I hope you are doing well today. I see you are noticing some differences when testing the two devices. To confirm, do you still have the Xfinity Gateway listed as your primary device when you check online, or have we switched your account to remove the rental, making the UniFi modem your main device?

I believe it’s my UniFi cable modem but I’m not entirely sure, is there an easy way to check?
