That sucker is turned on by default and XFinity is using your electricity to power up a public XFinity hotspot. Totally lame, I killed it ASAP in the XFinity My Account application as soon as I realized that. Next thing I did with the rental was turn off the WiFi by switching the unit into Bridge mode. Just some advice for people still renting.
