While the small device may seem a rather complicated, just don’t fret! A simple knowledge and understanding of a few of the constituents and the specs can help you look for the right modem. Here we have listed some of the essential specifications you need to be aware of to make the best choice:
Perhaps the very first thing you need to consider is the compatibility. Even the world’s best modem is no good if it is not compatible with your ISP. So, before bringing that modem home, take a look at the approved lists of the ISP modems. You can easily view the lists at either of these websites:
- Wow way
For the best performance, the DOCSIS 3.0 is the best choice. This usually gives you a downloading speed of 340 Mbps and an uploading speed of 130 Mbps. You will often find the premium modems will give you a much higher performance and faster speed.
When looking for the best modem, you must consider the speed of your current service provider and try to go for a higher speed than the current Mbps you are getting.
But, don’t fall for the models that boast high speed only. Make sure whatever you get is compatible with your internet service plan. If you are considering a modem with a higher speed than your service plan, you will still get the same speed as you have agreed to with your service provider.
One of the most common causes of malfunctioning of modems is overheating. These small devices tend to heat up, fast. Some of the modems may even cross over 100 degrees Fahrenheit when in use! Just make sure to thoroughly read the reviews and go through the details of the modem before making your final selection.
Here are also some other tips to keep your device from overheating:
- How to Keep your Device Safe from Overheating?
- Make sure to keep the device in a ventilated area.You can also buy a separate cooling mat for placing your modem.
- Avoid falling for the cheaper brands and models. They have a higher chance of getting overheated.
- Don’t keep anything on top of the modem.
- You can also disable the services you do not need from the modem. This way it will generate less heat.
- Take special care during the extremely hot weather, and make sure to give your modem a break at least once in 24 hours.
- Do not keep the modem in an area directly exposed to the sun.
- Do not keep the router on leather or other heat receptive materials.
- Do not keep it switched on through the night. Power off when not being used, especially if you are leaving your house.
Usually, you will get a one-year or two-year warranty with these modems. Although it is not common for the modems to malfunction or stop working, the warranty keeps you safe if any of these issues arise later.
The best companies give you a replacement or refund ASAP and hence, your money is always safe.
The Number of Channels
Next, check for the number of channels the modem is most probably going to be able to access. You will need these channels for uploading as well as downloading. Now how to check for these channels? Simple, just take a minute to read up the box or general specifications. You will find the number written something like 00×0.
The key is, the more the number of channels, the greater the speed. However, there’s a catch; you need to make sure that the number of channels supported by the modem and the number provided by your ISP match!
Which Modem to Buy?
The question remains, which Comcast modem should you get?
Speed: Well, the minimum you can ask for is that it should at least have a greater speed than the connection you have at present.
Price: Make sure that whatever you are buying is within your budget. You will find lots of cheaper models that promise the same high performance and speed, however, fail to deliver. So it is recommended to go for the strong brands and the models that come with a good rating.
Capability: It is always the best to go for a modem that is most capable and can keep up with the latest upgrades and speed.
If you compare the costs of paying rentals every month for the internet service, versus buying a modem yourself, the never ending costs of the rental for the internet service over-weigh the one-time expense of buying the modem.
The latest and newest models are really simple to set up; so, why depend on your service provider? Get your own modem and make the best use of the high-speed browsing and much more, without any worry. No need to pay those upsetting bills and rentals every month; get your modem today and start saving!
