Comcast made Wi-Fi motion sensing a headline feature on millions of Xfinity gateways. It reads the ripples your body makes in the signal, through walls, no camera. Here’s the five-minute check, friend.
🤯 WOW! Comcast made Wi-Fi motion sensing a headline feature on millions of Xfinity gateways. Your router reads the ripples your body makes in the signal: which room you’re in, standing or lying down, through walls, no camera, no light. And the fine print says motion data can go to law enforcement “without further notice to you.”
The Short Version: Open your router app, hunt for anything labeled motion, sensing or Shield, and turn off what you didn’t turn on. Steps below.
I bet you never thought of this. Comcast and others hope you never do. Let me explain.
Every Wi-Fi signal in your house bounces off the walls, the couch and you. Wi-Fi sensing reads the ripples your body makes. A few weeks of that, and the box knows when you wake up, when the house sits empty and which nights you fell asleep in the recliner.
That’s not a motion alert. That’s a diary.
Researchers have identified specific people by their signal ripple with near-perfect accuracy. Not “someone’s home.” You.
📶 The walls have eyes Comcast’s new Xfinity Shield turns any XB7-or-newer gateway into a motion detector, free. Your printer, smart plugs and Xbox become the sensors. $15 a month adds a camera and 24/7 response. Comcast’s pitch: “The network should do more than connect devices.” Linksys sells a version called Aware.
Now the fine print.
Comcast’s policy says it may disclose Wi-Fi motion data “without further notice to you” for any law enforcement investigation, any dispute Comcast is in or a subpoena. Comcast says it doesn’t monitor the motion. Fine. The door’s still open. Your camera has a light. Your mic has a rule. This has neither.
Bright side: This can catch Grandma’s fall without a camera in her bathroom. Used with consent, I like it. Used quietly, I don’t.

Best way to make sure it’s not a problem

I’ve also subscribed to Kim Komando’s newsletter. I used to listen to her radio show back in the day but lost track over the years.
The “Digital Godess” is still out there!
This has nothing to do with your cell phone.
But requiring a Xfinity app does.
Bump for later...
It would only become a Fourth Amendment issue if the government had unwarranted access to the info.
if you’re using your own wifi router and not comcast’s, then build a little Faraday cage out of hardware cloth [a type of wire mesh] or similar material and slip it over the comcast router ...
Several makers of hearing aids also leverage this tech.
Best bet, use your own purchased cable modem (~$79.00) and skip the Comcast/Xfinity monthly modem charge ($10.+/mo. lately?). Than add a WiFi router to your cable modem with the firmware flashed to “Open Source” firmware to avoid any Chinese router spying.

Sadly, we had a former CIA Director as President (George H. Bush) when the digital age started. Rules, an operating framework was created in the digital world, which was ENTIRELY out of step with the spirit of the US Constitution. What we allow in the digital world is not permitted with snail mail, or in person, but digitally it's all permissible.
Basically, if it's over IP it's in the public space as far as government is concerned when it benefits them or large corporations. They have an entirely permissive environment.
That said, the Internet grew, everything became networked, smart, data storage cheap, processing power enormous, databases became really intelligent - and every last detail of your existence is digital and readily available.
Sure, our government created trash like HIPAA but that is no barrier for government. That is only there to make sure if your daughter wants to an abortion she can keep it a secret from her parents: https://media-cldnry.s-nbcnews.com/image/upload/t_fit-560w,f_auto,q_auto:best/msnbc/Components/Art/USNEWS/060308/AbortionConsent.gif A husband can keep his sterilization or STD contracted from an affair a secret. A wife can keep her positive HIV result a secret from the husband. Yes, HIPPA is so awesome, it can even keep HIV/AIDS a secret from coworkers.
But when it comes to your true privacy, where it matters in terms of freedom of religion, speech, fair elections, the government using these capabilities to go after political opposition (J6 - Trump tower), there you have NO PROTECTION.
The only protection the American citizen really has is some government agency (which hides behind secrecy) telling you to trust them, they have policies and procedures in place to prevent misuse.
Do you have that level of trust in your fellow man and government?
There is nothing in place to truly protect the Americans privacy, ABSOLUTELY NOTHING! Because government early on saw the benefit, they created a framework of rules that allows them to do whatever they want, they are themselves one of the biggest culprits! And of course corporate America got the keys to the kingdom also. And you are left to believe that you have privacy because you have a really hard to remember password and HIPPA (LOL)...
Bkkk
I have been hearing them advertise this on their commercials.
this tech is not new. Only the monetizing of it
Only if it’s Pagan Pink ripple....
Bkmk
Even if YOU eliminate wireless, your NEIGHBOR’S wi-fi router can spy on you.
Government can bypass the Bill of Rights by purchasing the data from private companies.
