Following trials that yielded “exceptional results,” Comcast’s Xfinity Communities unveiled Wi-Fi Ready, an offering in which wireless modems are pre-installed in multifamily units. The logic behind the offer is simple: Wi-Fi connectivity has become an expected amenity in the home. Now, upon move-in, new residents can purchase and activate their Internet service immediately, allowing customers to avoid the annoyance and frustration of scheduling and waiting for a service appointment.
