A guide to choosing a cable modem that suits your needs


There are so many cable modems on the market that it can be difficult to decide which one is best for you. For this reason, in this article, we are going to help you make a quick and easy decision about choosing the best cable modem, and also, understand how the right modem can affect your Internet bandwidth. So, if you want to learn how to choose the right cable modem, stay with us.

compatibility with ISP Check out


If you want to choose the right cable modem for you, first of all, pay attention to its compatibility with the ISP. When choosing a cable modem, make sure your ISP has approved the modem you want to use on their network. For example, if you want The first 5G mobile modem first, consult with the representative of this company about the best option and its price, and then decide to buy the option you want. Unfortunately, many people think that every modem is compatible with their Internet service provider, but this is not true in most cases. Therefore, it is important to be sure to use a certified cable modem.

Pay attention to your internet speed

If your Internet package is 300 Mbps, a 4×8 channel modem (with a claimed maximum speed of 343 Mbps or an actual maximum speed of about 215 Mbps) will give you the full speed you pay your ISP for. You do not deliver. However, a 16 x 4-channel modem (maximum claimed speed of 686 Mbps or actual maximum speed of about 372 Mbps) allows you to enjoy the full Internet speed provided by your ISP.

Remember that some ISPs will increase your internet speed for free for various reasons. Modems DOCSIS 3.0 They are nearing the end of their lives. So, instead of buying these modems, get a DOCSIS 3.1 modem.

From buying modems with chipsets Puma 6 Intel refrain

Many cable modems have Intel’s Puma 6 chipset, which can have known issues with latency or network jitter. Therefore, be sure to pay attention to this factor when considering different options and avoid buying it if the modem has Intel’s Puma 6 chipset.

Consider upload and download speeds

One of the most important things you need to know about the modem is its upload and download speed. Remember that everything advertised is download speed, not upload speed. So if a modem advertises a speed of 1GB, that means it can get up to 1000MB/s from the ISP. This is despite the fact that the upload speed is much lower and in fact, it reaches a quarter of the download speed.

All these things can be tempting and attractive but again remember that you can’t get more from your ISP than you paid for the Internet. If your modem download speed is 1.4GB but you subscribe to an internet plan that limits your speed to 25MB/s, then you only get 25MB/s. Buying a high-speed modem is only a good idea for the future, unless you want to get a faster internet package.

Do not forget the modem brand

Several companies make cable modems, but the most popular modems are ARRIS, NETGEAR, and Motorola. Cable modem manufacturers’ warranties range from one to two years. Cable modems rarely fail unless they overheat. Consider this issue when buying any type of antenna, including Internet booster antenna and TV antenna Any type of desktop and strong electric antenna Also remember and don’t just buy cheap devices.

What about security?

Unlike routers that have settings to make the internet more secure, there aren’t many security considerations to consider when buying a cable modem. At times, some security issues arise. For example, modems that use a system-on-a-chip (Broadcom’s systems-on-a-chip) may allow a hacker to take control of the modem and serve malicious websites. However, Broadcom claims that this problem has been fixed. So, before buying any modem, check with your ISP which modem is safe. Additionally, using a strong antivirus program can be very helpful.

Finally, to be able to make a better decision to buy a cable modem, remember the compatibility of the modem with the ISP, the speed of the modem and the speed of the ISP, and also, if the modem does not use Intel’s Puma chipset. Since there are many different cable modems on the market, it may also be helpful to get guidance from your ISP, as ISPs can provide you with the specifications of the Internet-compatible modem they offer. Currently, the best DOCSIS 3.1 cable modem is the Motorola MB8600, which is supported by most major ISPs.
