Downstream & Upstream Channels

Edit to thread title: Deciding on number of downstream channels for cable modem purchase

I haven't shopped for modems in a long time (over 10 years) so I am coming up short on necessary knowledge.

Right now I have 60mbps service with a cable provider.

I am considering some new modems that have 8 downsteam channels.
I also found a refurbished one that has 16 downsteam channels.

I read an article that said that users should always go with at least 16 downstream channels in this day and age. However, that sounded bogus to me and I am seeing other information that says that each channel in the US is 38mbps, so 8 seems like it's plenty for me (unless I am trying to make this purchase last for 5+ years or something.

I think that the limit of my household usage would be streaming one 4k movie.

Assuming that I am going to be staying with the 60mbps service for at least the next 2 years, do you think the new or the used choice would be better?

 

Most ISPs provide a list of supported modems for their networks. I would start there to see what options you have available to you.

I am NOT suggesting you buy from your ISP (I never do!). Just that you see which ones they have tested and verified are compatible.

While that may be your biggest hog, it is not uncommon for most households to have several "smart" devices - including TVs, Blue-ray players, even smart phones that use wifi when possible. And there may be times when guests want to stream something too. Just something to keep in mind.

 

I am the only one in the household that uses any broadband service. I didn't know blue-ray players would use a data connection. Maybe to download software updates?
Ok, I can buy one of the ones that is on the list from the ISP. I just wasn't sure how comprehensive their list was, and I thought it might rule out good options on the market. However, I can probably look at the specs of the ones that they have published and that can answer the question.

 

"Smart" ones do. Not just for firmware updates. Remember, Blu-ray (not "blue" - my mistake too) players are really little dedicated computers (so are today's TVs). When you insert a Blu-ray movie, they often run little programs that first look for a network connection and if found, will download previews for current and upcoming movie or even side programs and features to go along with the movie on the disk. I have 3 players in the house, 2 Samsung and 1 LG and they all support Netflex, Amazon and Pandora streaming too.

They might. I guess that depends on how thorough your particular ISP is. I have Cox Cable and as seen here, their list is pretty comprehensive.
