This is why I buy my own modem and own router. Eventually all routers will do this I guess, but I've got some control for now.

Yeah, I opted out of that free service and pay more monthly. No other options for gigabit speed in my neighborhood.
Also turned off wifi on the modem and have it in bridge mode. Only so much you can do but it’s better than nothing.

Check that setting again. Mine would default back to on monthly when they would push out router “updates”.

Their routers can barely maintain a stable wifi signal right next to them. Im notnworried about them being able to track neighbors. Plus metal tends to interfere with the signal. If youre really concerned, all some things metal plating to your outfit. Change it up daily. They wont be able to get a clear signal.

u/expsychotic Aug 18 '26
If you have xfinity fiber then this won't work because they force you to use their equipment. The auth credentials are baked into the hardware with no way for users to access. And they don't even offer bridge mode. It's awful

I keep mine in bridge mode and use my own router but on newer plans you pay for it one way or another since it's included in the price. It was cheaper than going out and buying a $100+ modem that is verified to work with faster upload speeds.
I do leave the Xfinity wifi and mobile hotspots enabled for my neighbors in case the power goes out (apparently I'm the only one on the damn block with a backup battery and generator) or if anyone uses it for their main internet like I did when I first moved in.

We recently lost power for 2 hours and I was surprised how many of my neighbors had battery backups! Easily half of the normal SSIDs I see were still broadcasting. Then again, I live in a tech-job heavy area so maybe not shocking.
I keep my network closet and my main work/entertainment area on UPS and it’s great for power flickers or actual outages.

Conspiracy guys were saying this ability of WiFi would be used for person tracking--the use of WiFi to detect bodies has been out for a while (couple years).
The ability of a technology does not necessitate it's use for a purpose. Someone has decided to use this capability, and it is that decision-making power that the 'privacy guys' have been warning about.

Comcast is turning millions of its routers into motion detectors Skip to main content
Comcast is activating free Wi-Fi motion sensing on Xfinity gateways, allowing its routers to detect movement at home.
Comcast is activating free Wi-Fi motion sensing on Xfinity gateways, allowing its routers to detect movement at home.
by Jennifer Pattison Tuohy
Comcast is bringing Wi-Fi motion sensing to millions of routers that are already in customers’ homes, turning the devices into activity monitors. A new update to the Xfinity Internet app, arriving today, August 18th, enables the feature on compatible Xfinity routers at no extra cost.
Announced as part of its new Xfinity Shield service, WiFi Motion can monitor activity in your home and send you notifications, similar to a standalone motion sensor. It works by detecting disruptions in the Wi-Fi signal between the Xfinity gateway and any Wi-Fi-connected device, giving you some insight into what’s happening in your home without buying additional hardware. Xfinity Shield is free for all customers and includes a new advanced security feature that protects devices from online threats, including malware and phishing attacks, and improved parental controls.
WiFi Motion sends notifications through the Xfinity app when movement is detected from Wi-Fi-connected devices in your home.
Wi-Fi motion sensing is a technology that has been around for a while, but it’s only recently that it’s become accurate and reliable enough to catch on. Linksys launched a similar service in 2021, but discontinued it a few years later. Lighting company Wiz launched a line of Wi-Fi-sensing smart bulbs in 2023, and more recently Philips Hue deployed a similar radio-frequency sensing technology in its products (using Zigbee rather than Wi-Fi).
Comcast’s motion sensing pairs with new modes in the Xfinity app — Home Watch, Away Watch, and Dark Watch (a night/sleep mode) — allowing you to turn sensing on or off based on your activities.

WiFi Motion can monitor activity in your home and send you notifications, similar to a standalone motion sensor.
They're really downplaying the technology's capabilities, given Wi-Fi can now identify you, individually, with near- perfect accuracy. 😬
But I'm sure this won't be abused at all. It's not like our gov't is some fascistic abuser of privacy and civil rights working hand- in- glove with the developers of these technologies to stifle opposition. Oh, wait...

u/J_Bright1990 Aug 19 '26
Ok I need some real advice, or rather a tutorial. How do I activate a new modem and router on my service?
I remember in the past it had to be plugged into a computer full time. Is that still a requirement?
9
u/WiglyWorm Aug 19 '26
No worries. You asked the right person, it's actually really simple. I'm gonna give you an info dump and you can ask any follow up questions you want.
First of all a modern modem isn't a modem. MODEM stands for "modulator de-modulator" and it was the device that used sound into 0s and 1s for computers. Those are the ones that were plugged directly into computers. They were just another input device for the computer.
Modern cable, satellite, or any other non-analog form of internet access uses the term "modem" because it's what everyone is familiar with, but in reality it's just a small computer with a serial number that it knows how to show an internet provider, and then the internet provider can check if that modem is authorized and send it internet if so.
All that said, here's the point:
Your ISP is required to let you bring your own device, so you can contact them in your preferred manner and ask them what makes/models of modems are compatible. It might be listed somewhere on their website somewhere if you dig, but honestly I wouldn't be surprised if they made it very hard to find or just don't provide the list without making you contact customer support.
So get the list, then run up to a Microcenter if you have one near you or just go online to microcenter and find a compatible model modem.
Your product options would be to get a modem/router in one, or a standalone modem and a standalone router. What works best for you is up to your individual needs, the size of the space you have, if you need options like repeaters so you can have coverage through the whole house, etc etc. A lot of this stuff you can buy piecemeal, and it's generally all standards based and interoperable.
In general I think for the money spent you get a better deal buying a basic modem and spending the money on a nicer wifi router, but if you're not going to set up a separate network for untrusted devices like your alexa home speakers or your lightbulbs or your enshitified wifi dishwasher then you definitely don't have to break the bank.
If you want a brand recommendation from me, I say buy a TP link, set a user name and password you'll remember on the router itself by following the instructions to point your web browser at the router config page (usually you go to something like http://192.168.1.101 or something. Type type ipconfig into your terminal and look for your default gateway address. That's what you want to go to in your web browser.
Once you get it home and get it hooked up, call your cable company and tell them you bought a modem and a router and you no longer need to rent theirs.
They will have you read a few numbers off the back of the modem, enter it into their system, and you will have internet.
Return the modem/router you were provided to your internet provider and make sure they stop charging you the rental fee. Your internet bill will go down.

honest answer? I've been wanting this because it is supposedly better than a normal IR sensor. I sit in my office and typing away and even slight shifts don't pick up. And wifi signal goes everywhere so more accurate (though, can't read the article so not sure this is what I think it is).
However.... I didn't comcast controlling all this (yes, I know stand alone radio based ones exist now but at the time questionable functionality with hubitat for me).

Already ditched Comcast Xfinity
Their Reddit operates like a authoritarian government, their moderators will aggressively remove or delete any post or comment with negative feedback. My attempts to get help and resolve major issues with service disruptions, customer neglect, price and billing issues were deleted promptly by the moderators
The service is shitty in the SF Bay Area with frequent outages in working hours and connection drops, not to mention multiple price hikes in the past few years.
Their customer service is endless AI bot loop which will do everything in its power to not let you through and talk to a person. The wait times on calls are hilarious and the app is useless and redirects you for the most basic tasks to the website, which is outdated and fails to load if you have Adblock and privacy settings on (adgurard, Adblock, etc)
So long Xfinity. If anyone from your leadership is reading: Your monopoly is destroyed by your anti-customer corporate decisions and it’s all a matter of time. ATT And Starlink make Xfinity look like a joke

Wi-Fi motion sensing is a technology that has been around for a while, but it’s only recently that it’s become accurate and reliable enough to catch on. Linksys launched a similar service in 2021, but discontinued it a few years later. Lighting company Wiz launched a line of Wi-Fi-sensing smart bulbs in 2023, and more recently Philips Hue deployed a similar radio-frequency sensing technology in its products (using Zigbee rather than Wi-Fi).
I tried the WiFi Motion feature (which is free to Xfinity customers with compatible gateways) and it sort kinda works if you have a compatible device (or devices) connected to your network. Furthermore, the WiFi Motion functionality (in its current iteration) can only use a set number of devices to detect motion, so I didn’t find it very useful when I tested in 2025. You have to sign up for Xfinity’s new Shield service (at $15 a month) and add their cameras and sensors to really make the whole thing useful, IMHO. Clearly Xfinity is trying to expand their home security services to better compete with competitors like ADT, Ring, etc.
Xfinity doesn’t see the technology as replacing traditional security systems with cameras and physical motion sensors just yet. “But for the average household … this provides an adequate level of security protection,” says Kuda. Xfinity already offers security cameras, and those remain available under a new service called Xfinity Shield Select. This costs $15 a month for an indoor camera and a door/window sensor and includes cloud video storage capabilities and a 24/7 urgent response service.
So yeah, Xfinity wants to sell you a Security/Alarm system.

Doesn't matter if you opt out. I'm sure there will be a "safety connection" to your local pig office that is shared with ICE and everyone else. Not only can they detect how many people and their locations, but their devices and therefore identity in every house.
I run all my own networking gear but I keep the ISP modem in bridge because it's way simpler than a dedicated 3rd party modem. With the ISPs if there's an issue and you aren't using their hardware, good luck getting service until every other avenue exhausted or you can prove there's an issue with their modem installed.

I feel so vindicated for ALWAYS bringing my own router, regardless of the clueless "technician" trying to get me to pay monthly for their spyware crap router. I'm not even with Comcast anymore, but they all try this.

You can turn this off. I have my own wifi but my echo knows where I am, my nest senses presence. I have motion sensors to turn lights on and off. So I don’t really care except there is a chance the wifi presence scan can record movements and shapes. I don’t need comcast to know that I dont get off my couch for hours.

The bad news: That won’t prevent this technology from working, because (according to Xfinity/Comcast) it uses any device that connects to your Xfinity modem/router to "see" and detect your movements.
The good news: you have to actually turn it on and set it up. It is not turned on by default and if you do turn it on, you can always turn it off whenever you want. 😁

In Baltimore City, I cannot get true symmetrical gigabit upload speeds from Xfinity using a customer-owned modem. Achieving their enhanced high-split or symmetrical multi-gigabit upload tiers requires using an official Xfinity Gateway (such as the XB8 or XB10).
I can have Xfinity switch the modem to bridge mode and use my own router and access points. But the modem continues to support other Xfinity services.
I was strongly encouraged to use the Xfinity router/access point in the modem. But it can’t support the functionality and coverage I need from my Unifi network in my brick and stone property.
The Xfinity modem may be using its access point to track people. But the tracking will likely apply to my neighbors, who are closer to the AP, more than to people on my property, who can be far from the AP with many barriers between.

ADT made the acquisition of the decade. This tech is going to make flock look like a fucking joke and they bought it's for $170m and are now licensing to comcast.

You'd have to be an idiot to believe that.
