They do, but you'll be charged a $200 (or more) "installation fee" if you don't bundle TV with it. When my service was installed, the guy literally walked in, plugged the modem into the wall, and was done. However, if you do order bundled TV with it, they'll prorate the fees if you cancel it... so I ordered TV + internet, cancelled the TV the next day, and now have an internet connection only (without paying their ridiculous $200 "plug it into the wall" fee). I only bought one day of TV service (the cost of which was negligible) and dropped the cable box off at UPS.
I would be using something else if there were ANYTHING else, but my apartment complex won't let cable providers wire the place. I'm moving soon, to hopefully greener pastures.
