Looking for recommendations for a modem for my landline
Since recieving the new XB6 upstairs for internet and WiFi and having to replace my phone modem in my basement, because it died after 5 years, it appears that the XB6 can not be indentified in the Comcast systems as my primary modem. Therefore I can not manage my connected devices because the phone modem is showing as my primary gateway.
I have been informed to resolve this issue I now have to purchase my own phone modem. I have looked at those available on the mydeviceinfo.xfinity.com, but still can't determine which will work with out interferring with the new XB6.
I am somewhat technically challenged and of course Comcast can not recommend which modem to choose. Any suggestions would be greatly appreciated, as this has been going on since June 20, 2019. Thank you
