Introduction

At Comcast Business, we want our customers to have access to lightning-fast internet so we strive to provide our customers with the speeds they require to run their business. Over the past five years, Comcast has increased internet speeds for existing customers. The following article explains what to expect when a speed increase is performed.

Time of day speed increases typically occur

Increases take place overnight (between midnight and 6am). The process typically takes less than 15 minutes to complete, during which time you will be unable to use your Internet service.

Once complete, your modem should automatically reboot. Open your Internet browser to confirm that your service has been properly restored. Your modem will now deliver the increased speed.

Verify your speed tier

Verify your speed tier by consulting your monthly Internet billing statement. Click here to see where this information is located on the bill.
