The Basics of DSL Modems

There are a few basics to cover before we go into our product recommendations. Let’s get started!

A Quick Overview of DSL

Digital Subscriber Line, more commonly known as DSL technology, offers a way of transmitting high-speed Internet through phone lines. Unlike its predecessor the dial-up connection, DSL allowed users to receive calls on their home phone while surfing the web, making it a game-changer.

In its early days, DSL gained a reputation for having lag issues. This could be a huge inconvenience to everyone from home business owners to gamers. Older ADSL standards were only able to deliver lackluster speeds using unshielded twisted-pair copper wire.

Thanks to rapidly evolving advancements, current technology, and decreasing costs of equipment, DSL lines have become faster over the years. The bit rate of typical DSL services can range anywhere between 128 Kbps to 3 Mbps.

The speed a consumer may see depends on a number of factors, including line conditions, implementation, maintenance, and DSL technology. Newer DSL technologies (discussed below) can reach speeds much higher and can compete with cable internet service.

What is a DSL Modem?

A modem is a device that lets computer users access the Internet from their desktop. In the earliest days of the Internet, dial-up connections relied on modems that were typically found inside of computers. Nowadays, most people have modems that are a separate piece of hardware. DSL modems are most often standalone units that connect to computers, routers, and telephone lines using cables.

A DSL modem, like a 56K dial-up modem, gives you access to the Internet through your home telephone line. It uses a DSL connection, however, allowing you to make calls through your landline even while online. DSL modems also offer faster service, giving you access to your favorite sites much more quickly than with a dial-up connection.

The Difference Between a Modem and a Router Combo

When buying a new DSL modem or replacing an old one, you can get a standalone model would would need to purchase a separate router or opt for an all-in-one unit. Modem/router combinations, also referred to as “gateways,” are easy to set up and can help to enhance your home Internet network.

Not only do combination modems allow you to connect to your ISP, but they also offer a wireless router function that lets you share your online connection with other computers and mobile devices in your household. You can connect either wirelessly or through Ethernet ports.

ADSL vs. VDSL

DSL users may be surprised to find out that there are several different types of DSL broadband connections that computers use to communicate. Businesses typically rely on Symmetric DSL (SDSL), which places equal emphasis on download and upload speeds.

Residential properties, on the other hand, most often use Asymmetric DSL (ADSL) services. These focus on download speeds, allowing families to access vast caches of information quickly. Over the years, ADSL services for residential homes have improved in terms of speed. Certain ISPs now offer faster connections of up to 12 Mbps using ADSL2 and up to 2 Mbit/2 with ADSL2+.

Very-high-bitrate Digital Subscriber Line service, or VDSL, offers up to five times faster download speeds and up to ten times faster uploads. In fact, maximum upload speeds can reach around 60 Mbits/s for users living close to their service provider. VDSL offers an improved experience by using phone line connections more efficiently than ADSL services.

Uni-DSL is a service proposed by Texas Instruments that would combine the best aspects of VDSL and ADSL to bring consumers and even faster broadband solution. Uni-DSL offers the prospect of speeds up to 200 Mbps, far faster than either current ADSL or VDSL options can provide.

The Difference Between DSL Speeds and Wi-Fi Speeds

The speed of your DSL connection depends in part on the modem hardware that you use. Likewise, the Wi-Fi speeds that you experience at home depend on the type of router that you use to connect your various devices to the Internet. Most Wi-Fi connections run on either 2GHz or 5GHz frequencies.

2.4GHz bands can cover a wider area than 5GHz frequencies. While this gives you stronger signals across a broader range, the trade-off is slower data transfer speeds. There are only 11 channels that 2GHz devices to connect to, making it easy to overcrowd the signal and force connection speeds to stagnate.

While 5GHz bands can’t reach as far as 2.4GHz bands, they pose less of a risk of overcrowding. There are 23 channels for devices to connect to, preventing channels from dropping or being interrupted. Download speeds also tend to be faster.

You can find three types of routers available on the market that support data transfer at different speeds. Devices are denoted by letters instead of specs set by the Institute of Electrical and Electronics Engineers, or IEEE. Consumers can choose between Wireless N, G, and AC models depending on their speed requirements:

- Wireless N (802.11N) routers are usually capable of operating at both 2.4GHz and 5GHz. They can transfer data at different rates depending on the number of antennas attached. Speeds can reach a potential rate of 450 Mbps if using three antennas or 300 Mbps if using two antennas, but speeds tend to average around 130 Mbps.

- Wireless G (802.11G) routers don’t support as fast of speeds as N devices. These models can only handle transfer rates topping around 5 Mbps and run only on the 2GHz band. G routers are often significantly cheaper than counterparts, however.

- Wireless AC (802.11AC) devices are relatively new, only hitting the market around 2013. AC routers can transfer up to 1 Gbps of data on a 5GHz band network or around 450 Mbps on a 2.4GHz band.

Can a Better DSL Modem Increase Speeds?

The modems that ISP providers offer often provide consumers with only the bare minimum. Rental modems may have suffered from wear-and-tear, or they may be older models that don’t support newer DSL technology. All of this can negatively impact the Internet speeds that you experience at home, especially if you invest in an expensive high-speed package.

Replacing an old, worn, or obsolete modem can help to improve your data transfer speeds so that you can get your work done more quickly. It’s best to look for newer modems that support current and future DSL technologies. ADSL2+ and VDSL modems offer some of the fastest speeds for residential Internet users.

If replacing a modem fails to improve speeds, the problem could also lie with your router. A router that doesn’t support high-speed connections can create a bottleneck effect, slowing down speeds when you try to access the Internet from a device that’s connected wirelessly to your DSL network. Wireless G offers the slowest rates, so if you’re looking for a quick connection, it’s best to look at N or AC routers.

When to Replace a DSL Modem

A lot of people only replace their modem when their own is broken. ISP companies often offer free support and replacement services for DSL modems, but it can take weeks to months to get your Internet in working order again.

Usually, it's a better idea to invest in your own modem. You can purchase a brand-new unit, and have it hooked up in just hours. Not only will replacing your modem save you time, but it will be cheaper in the long run. You'll save on rental fees and can keep the unit if you ever decide to switch ISP services.

Some users don’t wait for their old modem to give out before investing in a newer model. Replacing an old unit or an ISP rental with a brand-new DSL modem can immediately result in faster speeds and a more stable network. If you’re looking to improve your home internet experience, a new DSL modem may be all that it takes.

Replacing Your Modem

Different types of DSL require different modems to connect, and it’s important to purchase a compatible model. Most of the biggest ISP names allow customers to buy their own modems and will readily supply a list of approved devices. Customers can call a representative or go online to find out which modems are compatible with:

Comcast - https://mydeviceinfo.xfinity.com
Time Warner/Spectrum  - https://www.timewarnercable.com
Cox - https://www.cox.com/residential
AT&T - https://www.att.com
Centurylink - http://www.centurylink.com/home

Replacing your modem or installing a new one is a fairly easy task, even for the tech-illiterate. New modems often come with easy-to-follow instructions, or you can look up video tutorials online. If you’re replacing an old modem, you can usually follow its setup as a straightforward template.

Once you’re sure that your modem is properly plugged in and installed, you may have to contact your ISP to complete the setup. Some companies need customers to provide them with a new modem’s MAC address to activate or reactivate an Internet connection. The MAC address isn’t difficult to locate--it’s usually printed as a prominently labeled twelve-digit code on the back of a modem unit.

Purchasing and setting up your own modem can help to improve your online experience, but it’s important to remember that this may void service contracts with your ISP. Most companies will only provide technical support for customers who use a rental modem. If you have issues with your new modem, you’ll be forced to either fix the problem yourself, purchase a new modem, or start renting from your ISP again. While this can take money out of your own pocket, buying your own modem is still usually a cheaper option than renting.

Benefits of Buying Your Own Modem

There are plenty of reasons to invest in your own modem instead of renting from an ISP. Not only does a new modem make your connection faster, but it can also improve reliability. Newer devices also tend to last longer than rentals, which suffer a significant amount of wear over the years that can affect performance. It’s a good idea to look for a modem with a durable build, as a good modem should last for at least a solid five years.

Even though a new modem may require an initial investment, over the years of its life it will more than pay for itself. Having your own modem means you won’t lose money to your ISP through monthly rental fees. You also won’t have to return your modem to your ISP if you switch services, helping you to save money on future Internet plans.

In addition to monthly fees, many rental modems come with limited access to a web-based control interface. This makes it more difficult to monitor or tweak your network when looking to improve speed or performance. By buying your own modem, you’ll have easier access to handy built-in features such as traffic logs and signal quality charts when troubleshooting. You can also experiment with third-party firmware to improve your online connection.
