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

I remember when MIT had a paper on this around 2000

[–] Buske@lemmy.world 3 points 6 days ago

The show continuum used it too.

[–] blacklotus_@lemmy.world 2 points 4 days ago

Mad at the concept, but at least it's off by default. Had Xfinity for 2 years and was running my own modem and router anyway, so I'm all set if I decide to switch back at this point

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

Get your own gateway. Don't rent theirs.

[–] Semi_Hemi_Demigod@lemmy.world 49 points 1 week ago (2 children)

You can buy cable modems cheap, too. No reason to use their crap at all.

[–] JasonDJ@lemmy.zip 26 points 1 week ago* (last edited 1 week ago) (17 children)

"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.

Rental? How much is rental?

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?

[–] kieron115@startrek.website 5 points 6 days ago* (last edited 6 days ago)

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

[–] unphazed@lemmy.world 3 points 6 days ago

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?)

[–] JasonDJ@lemmy.zip 5 points 1 week ago

Not buying another modem when the ISP quietly upgrades the CMTS and makes more speed available in your neighborhood.

I used docsis 3.0 and it worked just fine. So why not?

[–] fuckwit_mcbumcrumble@lemmy.dbzer0.com 7 points 1 week ago (2 children)

Because docsis 3.0 standard is nearly 20 years old at this point and 3.1 is significantly faster. Docsis 3.1 is only 15, but 4 (which is still 8 years old) probably isn't supported by your ISP yet. But the speed difference is quite noticeable. 3.0 will theoretically do 1gbps down, and 100-200 up, but 3.1 could do 10 down and 1gbps up. In the age of symmetrical fiber internet those upload speeds are dire. 3.1 realistically gets you a symmetrical gig connection.

[–] Zorque@lemmy.world 13 points 1 week ago (1 children)

Ah, so 3.0 is fine if your internet still sucks. Got it.

[–] surewhynotlem@lemmy.world 5 points 1 week ago (1 children)

Exactly. So it's great for xfinity

I have a 3.1 modem but my ISP only has 3.0 speeds as far as I can tell. 1000/100 is their highest plan so the extra doesn't really do anything.

My modem is 32x8 and I can see in the UI that only 4 of the 8 upload channels are actually bonded to reach that 100, which is half of the 200 that 3.0 can theoretically do.

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.

[–] possumparty@lemmy.blahaj.zone 10 points 1 week ago (4 children)

Doesn't matter for me, my neighbors use all that shit. There's enough latent rf for them to triangulate literally everything happening nearby.

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.

[–] hansolo@lemmy.today 9 points 1 week ago

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.

[–] Glitterbomb@lemmy.world 18 points 1 week ago (1 children)

Oh boy, I can't wait for this new wave of paranoid customers claiming their wifi is watching them. Thanks, comcast.

[–] possumparty@lemmy.blahaj.zone 28 points 6 days ago

Well, it very well can be used for exactly that.

[–] rhythmisaprancer@piefed.social 7 points 1 week ago (3 children)

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.

[–] BussyCat@lemmy.world 12 points 1 week ago (3 children)

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
