What do the numbers mean on modems?
Cable modem channels are displayed as “downstream channels number x upstream channels number.” For example, 8×4, 24×8 or 32×8. For example, 8×4 means that your cable modem has four (4) download channels and eight (8) upload channels. The higher the numbers, the faster the speeds. (This varies – check with your ISP.)
What are the three types of modems?
There are three kinds of modems—Cable, DSL, and Fiber—that operate via different cable mediums depending on your Internet Service Provider (ISP).
What are modem sizes?
When you look at a modem, you’ll often see a number somewhere in its description, which can be anything from 8 x 4 to 32 x 8. It’s not at all clear what the average user is supposed to glean from this. The good news is that it’s simply a description of how many downstream and upstream channels a modem has.
What is a good downstream bandwidth?
Of course, the image and sound quality depend greatly on how much downstream bandwidth you have—for 720p, many people recommend at least 3 to 4 megabits per second (Mbps), while 1080p normally requires 6 Mbps or more. (Vudu specifies 2.25 Mbps for 720p and 4.5 Mbps for its HDX 1080p stream.)
How do I know my modem type?

What is the difference between 8×4 and 16×4 modem?
For example, 8×4 modems—that is, modems with eight downstream channels and four upstream channels—support a theoretical maximum of 343Mbps. A 16×4 modem generally tops out at around 680Mbps for downloads.
What does the 8×4 mean on a router?
Sometimes, you’ll also spot numbers like “4×4” and “8×4” when modem shopping. These indicate the number of downstream and upstream channels supported by the modem—which refer to downstream data (like streaming or browsing) and upstream data (like transferring files or sending emails), respectively.
What is Docsis 3.0 modem?
DOCSIS 3.0 enables modems to combine multiple channels to stream data, increasing the speed of both downloads and uploads. For example, 8×4 modems—that is, modems with eight downstream channels and four upstream channels—support a theoretical maximum of 343Mbps.
How do I know what kind of modem I need?
Make sure the modem is at least DOCSIS 3.0 compatible. DOCSIS 3.1 modems are future-proof, but they cost more. Choose a modem that supports your internet download speed. Double-check that the modem you want works with your cable internet provider.
