How to Increase Slow DSL Speed

Feb 16, 2022

A DSL – or Digital Subscriber Line – refers to the line that connects an internet user – typically a domestic or commercial customer who is using an internet service, transmitting digital data through a telephone line.

It is often the case that a slow DSL speed (a 'slow' internet) is blamed on the service provider. However, a slow DSL speed can be as a result of several different issues. If you are looking to speed up your DSL, you should look into these to find out if there is something that is affecting it.

DSL connections make use of copper wires to transmit the data. This is not as advanced as fibre optic or full fibre broadband cables – and hence, why there can be issues with the speed of your DSL.

Best Ways to Increase DSL Speed If you are having problems with your DSL speed, the best thing that you can do as a permanent, reliable solution, is to install fibre optic broadband, taking out the need for the potentially problematic copper cables. However, as of yet, this is not an option for every area in the UK. You can check whether ultrafast full fibre broadband is available to you, here.

In the meantime, here are some tips to how to increase your DSL speed if you think that it is slower than it should be:

Check for Viruses or Malware One of the biggest culprits in slowing down a DSL speed is a virus or malware attack. These can slow down your connection straight away, so if you notice that the speed of your connection has suddenly slowed down, you should first run your anti-virus software to check for a virus or malware.

You could also run a registry cleaner. This should clean up all of the malware that is old and broken on your computer, and (hopefully) speed it up as much as possible.

Run a Speed Test To be able to gauge exactly whether there is a problem, the extent of the problem, and begin to look at where that problem is, you should then run a speed test once that you have checked for malware and viruses.

You should start by asking your DSL provider to run a speed test. This will tell you if the problem is their end or yours. If the test shows that it is at their end, they should be able to deal with it.

If the test shows that the problem is not at their end, you can run a speed test yourself online. This will tell you what speed you are getting, allowing you to compare it to the speed that you are paying for. It is worth, however, bearing in mind that during peak use times, the speed may not be as fast as at quiet times.

Reset your Router That famous IT mantra of 'try turning it off and on again' is a mantra because, well, it often works. If the problem with your internet speed seems to be at your end, try this with your router. You could also try resetting the router to its default settings. This process should clear out any of the bugs in the system that are causing the slow DSL speed.

Reduce your Interference Interference can also be another reason for a slow DSL speed. This interference will normally come in one of two ways – through some of the devices that you are using nearby – especially if they use a frequency of 2.4GHz to operate, or through physical barriers such as walls, floors, and windows. If you feel that there are these potentials for interference in the building, then try to reduce these and see if this makes a difference to the DSL speed.

Install Wireless Repeater

A wireless repeater is useful if the problem that you have with your DSL speed is interference. It is essentially a box that can be placed between your router and your device, that can be used to extend the range of your router, reducing the chance of interference, and boosting the speed of your DSL for devices that are further away. Wireless repeaters are easily bought in electronics shops.

As long as your internet is being transmitted through a copper wire, there is the chance of having a slow internet as it is far less stable. As stated above, the best way to ensure that you have a faster and reliable internet connection is by using fibre optic cables to transmit your online data, reducing the potential for problems with your cable.
