Best DSL Modems: Top 3 ADSL/ADSL2/ADSL2+ Cable Modems In 2021

Best DSL modems

I am 100% sure you might be using a rented DSL modem from your internet service provider and still paying for it. And, there must be some additional costs as well on your internet bill. So it’s time to take one step further and trash that shit as I’ll help you in buying one of the best DSL modems —a modem that will be far better and faster than your rented one. 

I’ll share with you three of the best modems on the market today. They will be under your budget and at reasonable prices. After replacing your existing DSL modem, you’ll see a huge speed difference (if configured properly, you might see double the speed) and better performance. 

Reasons to buy a DSL modem/router combo.

Buying a DSL combo will cost you more. It will be an expensive deal for you. Moreover, these DSL combos are easier to set up as they don’t have more moving parts. In other words, one less device and one less line too. 

Reasons to buy separate DSL modem and router.

Buying a DSL modem is always a less expensive option. It will be easier for you to upgrade. As you know, the hardware of a modem technology doesn’t change much. On the other hand, routers technologies keep on changing. So buying both the units separately will be much easier to upgrade. 

So when it comes to upgrading, you need to upgrade the router portion only. Check three best cheap WiFi routers

Therefore, I don’t want to mix things up.

Buying guide: How to choose the best DSL modem? 

If you’re a DSL internet service user, there are two options for you. 

You can rent a DLS modem from your internet service provider. 

You can buy from the market on your own. 

Firstly, let’s talk about those who rent a DSL modem from their ISP. These rented ones can handle light-duty tasks, such as surfing the web, downloading and uploading files, social media, and other similar tasks. You might also see some other issues with third-party modems, such as compatible issues, lack of power and efficiency, etc. 

However, renting a modem from ISP will result in limited configuration options and features. Therefore, you can’t get the most out of your modem. In this case, the wise decision would be buying a separate modem from the market. Plus, you will be able to save some money every month. 

But, choosing the best DSL modem is not that easy, and it becomes more difficult when you don’t have any technical skills. Therefore, I’ve recommended three top modems for you above. Choose any one of them that suits you the most or read the following guide in order to buy on your own. 

Factors that should be in your mind before buying a new DSL modem. 

Let’s see what some crucial factors you should look for before shopping for a new DSL modem are. 

1. Check with your DSL service provider: 

The very first thing is to confirm the rules and regulations of your ISP. Are they allowing you to replace your rented modem? Are they letting their consumers buy their own modems? So it is better to check ISP’s approved DSL modems. 

2. Compatibility: 

It is essential to check the compatibility with your DSL service. It can be done by calling your DSL service provider. Ask them which type of DSL standard they use. The most common DSL lines types are VDSL or SDSL DSL. On the consumer side, it can be ADSL, ADSL2, or the latest one ADSL 2+. So call your ISP and ask them. 

3. Ports:

The number of ports on your DSL modem matters a lot. These ports can either be fast ethernet ports or gigabit ports. The gigabit ports are ten times faster than fast ethernet ports. 

Therefore, it is our first priority to check whether the modem includes gigabit ethernet ports. It would be best if you also look for the USB ports; however, USB ports are not that essential. 

Most modern or high-end DSL modems or DSL combos come with four Gigabit Ethernet LAN ports, at least one USB port, and one RJ11 jack for a standard telephone line. 

4. Additional:

There are many other considering factors as well. However, they all are common; therefore, I don’t think they deserve writing, such as speed, ease of use, WiFi settings, security, price, etc.  

FAQs: Most Common Questions asked about DSL modems. 

1. Should I buy a DSL modem? 

Ans. Do you think it is fair paying $5 to $10 a month? I am not sure maybe you’re paying more than that. Also, it is not about only a month. Month after month, it becomes a considerable amount. So, in the long run, you should definitely buy your own DSL modem than renting. 

Paying a rental fee is not only a reason behind it. There are several other reasons: lack of firmware update or outdated firmware, locked features, and even outdated modems. 

2. What Is a DSL modem?

Ans. The DSL term is stands for Digital Subscriber Line. In order to provide internet connectivity, you connect it to a computer via a telephone line. Moreover, it is a broadband connection. There are different types of DSL modems you can find on the market. However, these days combo modems are quite common. 

3. How do DSL modems work?

Ans. It is a very simple process between your computer and your modem. These DSL modems usually come with Ethernet ports and USB ports. One of these ethernet ports is used to connect your computer’s PCI slots via Ethernet cable. Once the connection is made, your DSL modem uses a technology called wireless access point to provide internet connectivity to various devices, such as your computer, printer, and other ethernet-enabled devices. 

Conclusion: How to choose the best DSL modem? 

This article—best DSL modems— include two DSL modems and one combo (basic wireless connectivity) – and the buying guide with FAQs. I always recommend people buying a separate modem and router. It is because of the easier upgradation. However, combos have their own advantages, which you can read here.
