Fwiw you can set their router to bridge mode and use your own. It is probably still doing some traffic analysis but certainly no ad injection. This is what I do to get unlimited data without paying their exorbitant standalone fee.

This is a completely out of reach solution for most people.

If configuring a router into bridge mode is too burdensome of a step, then Comcast is actually providing that person a service by forcibly managing equipment for them at that point. If only the stalking component of it could be made illegal with proper privacy laws instead of piecemeal app bans.

What a weird way to think about it. I often wonder why I have to take those brain-dead ethics courses at work, then someone like you comes along and reminds me. Comcast can only fully take advantage of people who don't have the technical skills to not get fucked, that is what is happening.

I doubt it's out of reach for someone who already wants to use their own equipment, like the person upthread who brought up this topic.

The parent post misses the main reason they sell these. It's not for the ad injection but because they broadcast a Wi-Fi hotspot that you cannot turn off, which shares your internet connection.

So what? You don't find it useful to be able to use Wifi in more places if you have an Xfinity login?

Not if they're sharing my connection…

I live in a densely populated city. The wifi spectrum is already horrendously congested. The last thing I want is my modem polluting the airwaves, degrading my service from inside my home, all for Comcast's profit.

That sounds absolutely horrendous. I keep getting surprised by how shitty Comcast can be, and at this point I don't know how. I'd get a 5G hotspot before I use somebody else's router.

How does it work, because there is no way to inject anything to HTTPS connections?

ISPs can monitor what you're browsing through DNS requests and SNI host headers and sell that data to advertisers who then inject personalized ads into ad supported websites.

The thing I don't get is why they need a spyware router in everyone's home. They own the infrastructure and know where all the traffic is coming from. They can do this with their own hardware outside people's homes.

I do wonder if they're sucking up LAN traffic data too, though, some of it which might be unencrypted, like smart devices talking to each other.

Not sure where you're located, but in California at least, I was able to add unlimited data for an extra $30/mo. I am still using my own modem and router.

It's incredible bullshit that they can pull this crap, but... well, at least it's possible. Here, anyway. Dunno if they offer that everywhere.
