PowerBoost® Information

PowerBoost is an enterprise wide feature that provides our Internet subscribers’ modems with a short boost of performance in download speeds.

The boost occurs during file downloads and when loading complex web sites. During this window you may see an initial boost to download speeds for about 3 seconds, then your modem speed returns to the normal level.

The speed and length of PowerBoost is dynamic, fluctuates, and is dependent on network traffic.

PowerBoost is not available to Lite or Ultra subscribers.
