PLYMOUTH – Almost a million Comcast Xfinity Blast! subscribers throughout Michigan will soon get a big boost in download speeds, but not a big boost in price. The upgrade rolling out across the state through December is free.

Comcast on Thursday announced it will increase speeds of some of its most popular Internet tiers over the next several weeks throughout Michigan – without an increase in price. 

Download speeds for the company’s Xfinity Blast! tier will jump from 75 Mbps to 100 Mbps, while Performance tier speeds will more than double from 25Mbps to 60Mbps. Customers of the Performance Starter tier will see a similarly sized boost, from 10Mbps to 25Mbps

Rollouts of the new speeds will begin in early November and continue through mid-December, and will be available across most of Michigan. 

“As our customers continue to bring more devices and smart appliances into their homes that require fast, reliable Wi-Fi, we’re delivering more value by increasing speeds,” said Tim Collins, senior vice president of Comcast in Michigan. “We’re once again boosting the speeds of our most popular tiers to stay ahead of our customers’ increasing demands and ensure they continue to have a great online experience.”

To get the new speeds, customers may need to re-start their modems, which can be done manually or through the Xfinity My Account app.  Comcast will notify customers and provide instructions before the changes take effect. 

Comcast spokesman Rob Ponto said the upgrades would impact about 80 percent of Comcast’s Michigan customers, or about one million homes.
