Comcast announced it is increasing the speeds of its Xfinity Internet service packages for existing customers in Colorado at no additional cost. Speed increases will vary based on the Xfinity Internet customers’ current speed subscriptions, and the majority will see an increase of 50 Mbps. New and existing customers can expect to experience enhanced speeds this month. To get the increased speeds, most customers will simply need to re-start their modems when notified by Comcast that the new speed is available. Comcast will also notify customers who may need to upgrade their modems to receive the increased speeds. Those who own their own modems and need to upgrade them to receive the increased speeds will need to purchase a new one or can lease a new modem from Comcast.
