Xfinity Storm-Ready WiFi includes a Storm-Ready device and Battery Backup to help keep your home online for up to four hours through network and power outages with cellular data at no additional charge.

During an outage, the Storm-Ready device automatically switches from broadband to cellular 4G LTE connectivity, and when activated, internet speeds will be reduced to speeds up to 30 Mbps download/7 Mbps upload. Actual speeds will vary and are not guaranteed.

When there is not an outage, the Storm-Ready WiFi functions as a WiFi extender and eliminates dead spots, similar to our WiFi Boost Pods.

Storm-Ready WiFi features
