Why Has My Broadband Slowed Down?

There are a number of things that can affect your Internet speed and stability. You should normally expect some fluctuations in service during the first week of service as the line stabilises and the best connection is established for your line. This is nothing to worry about and is a normal occurrence; you should find that it gets better and you are able to have a reliable, speedy connection within a week or 10 days.

Faults on Your Broadband

When broadband is connecting and disconnecting regularly, you are likely to have a fault on your line and this can cause drops in speed. After disconnection, it can take up to 3 days for broadband to stabilize. If there are a lot of disconnections, then your line may well try and slow your broadband speed to get to a level that there is stability.

Faults on Your Telephone Line

ADSL broadband comes through the telephone line, and therefore, any problems with the wiring or the line will result in speed issues and disconnections. This is a very common reason for problems with your broadband.

If your line is fixed, the problem will probably go away immediately and it’s possible for your providers to run a quick test to find out whether there are any faults on the line.

Wireless Connectivity

There are a number of factors that can improve or diminish your Internet speed over wireless connectivity.

  • Obstacles can block the signals- Your router should be well-placed and not behind obstacles
  • Higher is better- Your router should be high enough to get a signal through your house.
  • Proximity is the key- You should not be connected too far away or you may suffer poor quality connectivity on your device. Don’t get within 2 metres either.
  • Premium routers- You may want to upgrade to a premium router if you have a big area in your house for the signal to travel to.
  • Signal Boosters- It’s also possible to get boosters to relay the signal further into the depths of your house.

Incorrect Setup of Microfilters

If you haven’t got your microfilters connected properly it will not be possible to get the best possible broadband. Many intermittent connection and speed problems are a result of microfilters not being placed where they should be placed, or not being connected properly.

In addition, it is important to avoid long telephone cables as they will not pass the Internet data very well. If you perceive that the microfilters are not doing their job, then it’s possible to upgrade to better quality microfilters than you received from your Internet service provider. The ones from your ISP may not be top quality to say the least.

Weather Conditions

Thunderstorms and heavy rain can dramatically affect Internet speeds. A storm may even cause permanent damage to the apparatus and therefore require the intervention of an engineer. During electrical storms it may actually be worth taking your equipment from the socket so that it doesn’t get broken. Bear in mind turning off may mean the connection has to stabilize again after being re-plugged.

Interference from Electrical Devices

It is possible to have interference from electrical devices in your home and even from the neighbour’s home. Electrical devices such as alarms, lights, boilers, and TVs, can really affect the performance of your wireless signal. You could try turning things off to see if it improves matters. Ensure that your broadband router doesn’t have electrical devices too close.

Your Computerised Device

Some older computers and laptops struggle to receive the broadband connection due to poor wireless receivers. In addition, viruses can cause issues so it is important to run spyware, adware, and Trojan detection tests so you can remove these. Infections can drain your bandwidth in the background.

Top Tip

If you’re asking yourself “How do I test my broadband speed?” the easiest way is to get online and search for a provider that will provide you with your ping, upload and download speeds. Test both plugged into the Ethernet and wirelessly in order to find out whether you have a problem on your line setup, or if the problem is through your wireless connectivity.
