I had Comcast come to the house and they determined that the cable modem in my house is actually theirs, lol! I thought it was mine. Anyhow, I think it makes sense to buy one, because otherwise I have to pay 10 bucks a month to rent for the rest of my life.
Now I just have to figure out which one to buy.
The Comcast guy, a really nice knowledgeable dude name Jason, said he couldn’t recommend, but that a lot of customers had Arris Surfboards. I found this one on Amazon. The confusing thing is this: Jason said get 150 megabits per second (for around $60-80), but I can’t find that spec on this one. Is that the same as download speed? Because then it looks like I want the the faster one (not the one linked here), which is a higher price point than what Jason said.
We’ve had an Arris CM820 Docsis 3.0 8x4 for 3 years and have never had a problem.
From what I’ve seen, pretty much any Docsis 3 modem on the Comcast approved list that otherwise meets your needs should be OK. I WOULD recommend staying away from a massively integrated WIFI / VOIP / etc gateway, however. When any one of those bits needs upgrading or breaks you’ll dump a relatively more expensive piece of gear.
Oh, thanks Lee, especially for linking the write up. Here is the Amazon link for the 6141, for the benefit of others who might want to buy. It’s actually cheaper and looks like the download spec may not be the relevant one for the 150 mps that Jordan spoke of, as this one is even lower than the one I posted above.
That is the exact model I have (the SB6183) and it’s great. Tops out at 686 mbps, so no worries about handling 150 or really any sane speed anyone is likely to need in the near future, but obviously if you were to get gigabit you’d need to upgrade.
I might be a little dyslexic this morning. For some reason, it didn’t click for me that 150 mbps is slower than 686 mbps (or even 343 mbps for the 6141). I blame a lack of coffee. Ignore my blathering about specs above!
I have read that the ability to lease more channels, besides increasing the maximum speed the modem supports, might also make for more consistent speeds and/or getting closer to the assigned speed for your service. Anyway that was the theory on which I got the 6183. (There wasn’t a higher model at the time, I don’t think.) Dunno if that’s true. I’m generally getting about 125-130 mbps of the 150 rated and Comcast said that was doing quite well.
Comcast’s gigabit-over-coax Internet requires a new kind of cable modem. That device is charmingly classified under a new DOCSIS 3.1 standard,
an acronym for Data Over Cable Service Interface Specification. And
while it looks like any other black box, this new standard is capable of
pumping data at 10 Gbps over existing coaxial cable. Still, Comcast is ushering in its new service with only a tenth of that power—currently offering one gigabit per second downstream speeds with 35Mbps upstream.
From what I can tell it runs 130 or 140 per month, unless you have a competitor with gigabit in the area, then you can get 70 per month with a three year contract (at least, this is what they are doing in their current areas). The caveat to that is that you can’t bundle the service with triple play, so if you currently have bundled service, it would wind up costing you more than that. Unfortunately, while CenturyLink has some gigabit service in Seattle, it isn’t in our area.
It’s a pretty niche thing in most markets, but I think a lot depends on the pricing. Last I heard Google Fiber didn’t charge any more for gigabit service than I’m paying now for 150 mbps with Comcast. Under those circumstances I don’t know why I wouldn’t.
