Xfinity Pro WiFi Extender Battery Backup: What It Does

Xfinity describes its Pro setup as combining an extender with cellular backup; a separate Battery Backup is needed for operation during a power outage. Confirm the current package and service requirements before relying on it.

Xfinity Pro WiFi extender battery backup is for households considering how to keep connectivity during an outage. Xfinity’s support information says the Pro WiFi Extender can switch to a cellular connection during a network or power outage when Battery Backup has been purchased; the backup unit is sold separately. It is a continuity feature, not a guarantee that every home device or service remains available.
