Modem vs router difference4/27/2023 ![]() ![]() ![]() Lastly, you want to make sure if you purchase your own modem, that the modem is compatible with your ISP. But since we are discussing Coaxial modems, the upload channel width should be at least 4, 8 if you want to prepare for the future. If you have a fiber connection the download and upload speed are usually the same. Most ISPs give you less upload speed than download speed over a coaxial connection. The second number is for the upload channels. If you have a “gig” download speed you want to make sure you have the 32x4 modem. This, in most cases, determines how much download data your ISP can allow you to have at one given time. This may mean nothing to an average user, but the number before the “x” represents how many downstream channels the modem has. Often, on a modem, you will see a number like 8x4 or 32x4. The second factor in determining which modem to buy is the “x” factor. So if your local ISP speed is above 100 Mbps, this is a big determining factor for your speed throughput. Only DOCSIS 3.0 and above modems can do this. That way, even if only a little data can get through each channel, bonding them together will allow you to push that data through multiple pipes at one time thus helping to work around congestion. DOCSIS 3.0 (and above) cable modems can bond multiple channels together, using the capacity of each channel, to provide one big pipe and allow for maximum throughput. I would not recommend usinganything lower than DOCSIS 3.0. Most of the newer modems are DOCSIS 3.1 and some are DOCSIS 3.0. The first thing I would check is to see if the modem has DOCSIS (Data Over Cable Services Interface Specification) 3.1, 3.0, or lower. There are many brands of modems, but here are a couple of things you’ll want to look for when purchasing a modem. But how do you know which modem to buy? What are the specs? So over time you pay much more for the modem than you would by purchasing one outright. If you acquire a modem from your ISP, in most cases, they rent them to you and you are charged for it on your monthly bill. Most coaxial modems can either be purchased through your local ISP or be bought locally at a store. Fiber modems, in most cases, are unique devices that will be given to you by your ISP and may not be easily found in stores. Cable modems are the most popular modems that are used by most ISP's. As mentioned above, there are 3 types of modems that your ISP can offer: Cable, Fiber and DSL. A router connects computers together so they can share a modem.Ī modem receives information from your ISP through a coaxial cable, optical fiber, or phone line (depending on which type of service your ISP offers) and converts this into a digital signal. At the most basic level, a modem connects your computer to the Internet. In other cases, you might not be provided with a modem at all, and just an ethernet connection out of the wall for a PPPoE connection directly to a router. In some cases your local Internet Service Provider (ISP) might provide you with (or make you rent) a modem/router combo. Both devices have different functionalities within your network as well and serve different purposes. Both devices play a huge role in your network setup. This will also help you determine what to look for when purchasing a new modem or router to make sure you have the best device for your needs. Today we will be discussing the differences between a modem and router.
