Rating of TOP-7 ADSL-modems: review and features of the best models 2026

An ADSL modem is a device that allows users to connect to the internet through the telephone network. While it may not be the fastest method available today, advancements in technology have allowed for much faster and more stable connections compared to the early 2000s.

In the past, connecting to the internet required a home phone line. Users would have to choose between having a telephone connection or internet access.

Fortunately, technology has advanced and become more accessible. Users can now easily set up wired internet connections in their homes, purchase SIM cards for mobile internet, or invest in a router with modem capabilities to stay connected at all times.

An advanced technology called ADSL offers various speeds for transmitting both incoming and outgoing data.

How to choose an ADSL modem?

Just a heads up! ADSL is a type of internet connection called an asymmetric digital subscriber line, where the download speed is faster than the upload speed.

Interestingly, the further away you are from the telephone node, the slower your data exchange will be.

In order to have a smooth, stable, and fast internet experience, it is crucial to choose the right device that can provide a high-quality signal.

To achieve this, it is sufficient to keep in mind the main criteria for selecting such a device.

1. There are different types of DSL technology available, such as ADSL, ADSL2, and ADSL2+. These variations vary in terms of bandwidth capacity. A modem of the ADSL2+ type can provide a maximum incoming traffic speed of 24 Mbit/s, while the other two types can support speeds of up to 8 and 12 Mbit/s, respectively.
2. The availability of different annex standards also plays a role in DSL technology. Annex A, being the most widely supported standard, is generally considered to be the most optimal. Annex M, on the other hand, offers faster speeds but may not be supported by all providers. Annex L is known for its susceptibility to interference but excels at transmitting data over long distances.
3. The presence of a DHCP server can greatly simplify the configuration process for the device. With a DHCP server, there’s no need to manually assign IP addresses to each device on the local network.
4. There are two methods of connecting to the device. An Ethernet port provides a stable and interference-free connection, while a modem with a USB connection is cheaper but less reliable. It is suitable only if you want to connect only one gadget to the Internet.
5. The number of LAN ports is important. You need more LAN ports if you need to connect multiple stationary devices to the network. This is especially relevant for office systems, as at home you can connect via Wi-Fi.
6. The wireless standard is also important. The most popular and widely used standard is 802.11n.
7. Wireless speed is an important factor to consider. The classic variant is 100 Mbit/s.
8. Antenna type is another factor to consider. There are removable and non-removable antennas. It is preferable to have removable antennas as they can be replaced with more powerful ones if needed.
