Mine up until a few months ago. Didn't really care because you'd have to stop literally in front of my house to access it. And living on a street with only about 4 properties, that would merit a visit from me asking why you're parked in front of my house.
I'm not sure Comcast would even let me do that today, though I haven't tried. I gave up running my own home router and WiFi a few years ago, they just made it too much of a PITA.
I genuinely don't recall the last time I saw one of those that didn't require me to at least go to a registration page to accept the terms and conditions in order to actually transmit any traffic.
