It's $25 here but it requires that you us their modem/router combination (which basically broadcasts free internet to anyone nearby through the xfinity hotspot and is known to have countless security issues) and a bunch of other bullshit such as a lack of networking options and Xfinity knowing even MORE about what goes on in the house through their "free security" that comes with it.
I'm pretty damn open with my data but the last thing I want is for comcast to have such control over it. I like having my own network.

Yes, I'm literally paying *more* to have unlimited data and own my own modem/router (both of which I paid for) but I wasn't in the mood to really argue last time.
You can turn off the hotspot and also turn the modem to bridge mode and control everything through your router. I've had it for a few years now and it isn't bad. Also, I believe they let you use your own modem now.
