SeattlePi reports that Comcast is turning some of the Wi-Fi routers placed in the homes of subscribers into a “massive public Wi-Fi hotspot network,” but it’s doing so without giving customers the opportunity to opt out before the service is rolled out.

But, if you know how, you can disable it yourself. Here's how:

Log into your Comcast account page at customer.comcast.com.

Click on Users & Preferences.

Look for a heading on the page for “Service Address.” Below your address, click the link that reads “Manage Xfinity WiFi.”

Click the button for “Disable Xfinity Wifi Home Hotspot.”

Click Save

About 50,000 Comcast Internet customers in Houston will become part of a massive public Wi-Fi hotspot network, a number that will reach 150,000 by the end of June.

Update: Comcast has turned on the first 50,000 residential hotspots.
