Make no mistake, this is 100% going to be Comcast's alternative to more expensive surveillance options a la Flock, or workplace presence sensor arrays.

Regardless of the basic privacy invasion that we all know Comcast is doing. Buy your own cable modem and router. Comcast charges you to use theirs, so they pay for themselves in a couple years.

I tried... Comcast would "forget" the modem 3 times a month and would have to call and read them the MAC address again etc... fuck Comcast

Probably a modem problem honestly. I've been on and off comcast a few times and 3 different modems over the years. Only issue I've had were when my old ones got too out dated.

Possible that one was too new at the time but they claimed to support it was at the start of docsis 3.1 iirc as I had a similar issue with an older docsis 3.0 first

So glad I was able to get an alternate ISP. A good chunk of my life, Comcast was the only high speed ISP in the area.

If alternatives to Comcast were available was something I have been willing to pay higher rent for in my life.

[–] Raiderkev@lemmy.world 2 points 2 days ago

Yeah, I had a company called Wave that was since bought by or rebranded to Astound. I've had it about 8 years, and had maybe 2 outages. It's night and day.

What if you just use it as a pass through by plugging it into their router and then wrap theirs in foil?

I did have my own router and wifi at the time never wrapped theirs in foil tho... but I suppose why not... fear of overheating I suppose
