I remember when MIT had a paper on this around 2000
By default, WiFi Motion is set to detect even small amounts of movement in the motion-sensing areas, including motion caused by small pets.
holy shit lol
DOCIS 3.1 involves more than just speed. No point going over the speed limit if all the traffic lights are timed based on a certain speed. https://www.cablelabs.com/blog/how-docsis-3-1-reduces-latency-with-active-queue-management
Oh boy, I can't wait for this new wave of paranoid customers claiming their wifi is watching them. Thanks, comcast.
Well, it very well can be used for exactly that.
Get your own gateway. Don't rent theirs.
You can buy cable modems cheap, too. No reason to use their crap at all.
"cheap" is a relative term.
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.
If a DOCSIS 3.0 modem still can't be saturated by the tier of internet someone is paying for, what advantage would 3.1 have?
Yeah I recently switched from cable to fiber (finally available), and prior I was using an old as fuck modem/router that capped at 500Mbps. My internet at fastest was 380. I rarely transfer files over the network, so figured why bother? (I did have Gen1 Google Mesh though to cover dead spots). I had a bit of a shopping splurge when I got fiber. Nothing crazy, just an upgraded mesh and a switch (Why the fuck does Frontier provide an ONT with 8 ethernet ports but only one is active?)
If your provider has implemented it (Comcast is the only one i know of in north america) then Active Queue Management is a huge quality of life improvement that you won't know you were missing unless you already had a router that implements queue management. https://www.cablelabs.com/blog/how-docsis-3-1-reduces-latency-with-active-queue-management
Not buying another modem when the ISP quietly upgrades the CMTS and makes more speed available in your neighborhood.

It looks like DOCSIS 3.0 and 3.1 are for coax which should be avoid anyway . VodafoneZiggo is already starting with DOCSIS 4.0.
I still use coax because I buy internet from a reseller third party and this is what they have. I have 400/50 for 35$, which is a lot cheaper yhan the competitors. No reason for me to change.
Can confirm, I live out in the countryside with only coax available, and a measly 1Gbit down 150Mbit up and 9 - 11ms ping. No caps.
Wait, that’s awesome and steady and reliable. Expensive sure but with heavy multiperson usage and no noticeable issues, I am wondering WTF you’re on about unless it’s some weird edge case?
Maybe you are referring to predatory business practices like oversubscribed lines? That’s not a technical problem.

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.
Doesn't matter for me, my neighbors use all that shit. There's enough latent rf for them to triangulate literally everything happening nearby.
I live in an apartment building. I wonder if this is useless tech with dozens of WiFi networks from my neighbors going
If anything it's far more dangerous tech due to that. Let's say you live in 304; They know who lives in 303, 305, 203, 204, 205, 403, 404, 405, and the likelihood that your neighbors aren't as tech savvy and use ISP provided routers and modems means that they can use all of those sources to create a 3d image of you and your apartment with the proliferation of 2.4ghz and 5ghz to create a high resolution image that can track your lip movements and even your keystrokes on a computer. That basically just becomes a multi lens 3d camera recording at 5000 fps. The only way to avoid this is to faraday your entire apartment which ironically makes your signal much higher due to the deployment of countermeasures. The ol' "huh, interesting, what are they hiding?" approach.
What the actual Batman fuckery is this. I hope you are wrong or nobody is that motivated to do such things. Either way, scary! Where’s my tin foil hat?
I really fucking hope I'm just being paranoid, but this is absolutely possible given the already existing research. AI isn't going to launch nukes, it's just going to facilitate horrors beyond our wildest comprehension.

Didn't read the article, but it's possible to get a 3d map with wifi. They can probably see you.
There is no privacy or security.
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.
