We have identified two isues with certain Xfinity routers when used with Sonos. One is that Sonos controllers are unable to connect to any Sonos players. The 2nd issue we have seen is that music services are unable to be reached from Sonos. This stems from an issue with the Xfinity routers parental control setting.
An XFINITY compatible wireless modem allows you to easily and conveniently share your bandwidth. XFINITY High-Speed Internet from Comcast is powerful enough to accommodate multiple devices, as well as tablets, Internet enabled phones and other wifi devices that all require an Internet connection to operate. Just connect all your devices to a compatible XFINITY wifi router. While an XFINITY compatible modem can easily deliver an Internet connection to any of these devices with a simple Ethernet cable, why not make it easier by sharing your bandwidth with multiple devices wirelessly?
