About 85 percent of Comcast’s Washington internet customers saw their download speeds increase this week, according to the cable giant. The company boosted speeds for customers with the Performance Plus, Performance Pro, Blast! Pro, and Extreme Pro internet packages.

Comcast is increasing download speeds across its western division, which includes California, Texas, Oregon, Arizona, Colorado, New Mexico, Idaho, Minnesota, Kansas, Missouri, and Wisconsin.

Comcast said the increases are designed to handle the growing number of devices customers are connecting to the internet. Smart speakers, watches, thermostats, doorbells, and other internet-powered devices are gaining popularity, especially in tech-savvy cities like Seattle.

Here’s what the increases look like for Washington customers:

— Performance Plus increased from 60 Mbps to 75 Mbps
— Performance Pro increased from 150 Mbps to 175 Mbps
— Blast! Pro increased from 250 Mbps to 275 Mbps
— Extreme Pro increased from 400 Mbps to 500 Mbps

Some third-party modems may not be compatible with the upgrade. Customers can find out if theirs is here.

Comcast says it has quadrupled its network capacity and doubled its miles of fiber cables in the past four years.

The company is also making a play for cord-cutters — internet subscribers who no longer pay for cable. Comcast announced last week it will no longer charge internet-only customers for its streaming device, Flex. In the past, customers could rent Flex for $5 a month.
