Nobody should be buying a DOCSIS 3.0 modem these days. They are obsolete and for some reason still being sold.
A decent DOCSIS 3.1 modem is at least $200. A Next Gen like S34 is at least $220. At least at the big blue big box store. And then you have to get your own wifi.
(However, that big blue store also will give you a 15% discount on any networking purchase if you recycle an old network device...I traded in an old modem but you should be able to find a switch or router at a thrift store and still come out ahead)
It pays for itself pretty quick (by not paying rental fees), but that doesn't necessarily make it cheap.
I absolutely prefer using my own equipment, and do...but it's also worth mentioning that in many markets, Xfinity removed data caps if you have a rented modem.
You can use your own. But at every single point they're going to tell you that your brand new top of the line modem, is out of date and is probably the problem of any issue that you're having. They try so hard to gaslight customers in believing that you need to use their white labeled equipment. They want you to use their stuff and pay the fees so they can resell the Wi-Fi, and they have full control over your device.
I have successfully avoided cable up to this point, but I did use my own modem back when I used DSL. It wasn't advertised anywhere, but I just took the details from their modem and called support for the last bit I needed and used my own. It worked well, and I had my router be separate so I was able to just toss the modem when I got better service.
Yes, look on their website for compatible models, there’s a handful of affordable ones, many which perform better on higher tier connections too. Been using my own modems with Comcast for 25 years.
You need to use their modem quite often, but you don’t need to use their router. They’re usually “all in one” modem/router things these days, but they’re legally required to provide you with a modem in bridge mode if you ask — at that point, an Ethernet cable attached to their modem is effectively attached to the Internet, and you can put your own hardware inside (firewall, Wifi router, etc.).
While you need to connect to their IP gateway, you don’t need to use their DNS services or anything but their IP gateway service.
Well yeah. That’s what their tech does. And it’s why I have my ISP’s WiFi offering disabled and the antennas removed and run their router in bridged mode, hooked up to equipment I own that doesn’t call out to the Internet.
It doesn’t really matter… the data is managed by a third party in another country. I have no real control over who gets access to it, intentionally or otherwise. Better that the data just doesn’t exist in the first place.
They don't need a 3D map, and the researchers who have rendered a 3D map need a lot of specialized software and resources.
Xfinity doesn't need that. They only need to know when people are online, what they're looking at, and who/how many people are watching TV, and if there's indication of pets in the house. That gives them an advertising gold mine of data.
I don't really understand how this works, so struggle to see any benefits (only drawbacks😐). It does make me thankful my provider is a small local company. Not the fastest, but probably no spying.
If you are interested I can try and find the article on it but a few years ago an article came out where they were able to use wifi signals with enough accuracy that they could see a password that you were typing on your keyboard!!
But basically they use the way the wifi signal bounce off things to make an image in much the same way that echo location works
Like - I’m excited about sensors that uses higher frequency versions of this for health monitoring. I think that’s a perfectly valid use. But also, in my use, I’d be installing it as an IoT device on a network I control, feeding data to services I own.
This use - where it’s opt in for now, until they figure out how to monetize selling how much time you spend in front of the TV, in the kitchen, bedroom, or bathroom (paired with ‘anonymized’ data about what you’re looking at online in each space) is creepy as fuck.
