How to troubleshoot Demon Internet internet performance problems

Demon Internet Internet speedtest - Slow broadband speed

Before starting to troubleshoot the performance of your Demon Internet internet connection, we recommend that you run a Demon Internet Internet Speed Test to confirm your current connection speed.

Also find out the minimum download speed you have subscribed to from Demon Internet.

You can get this information by checking a Demon Internet broadband bill, your Demon Internet contract or by contacting Demon Internet.

Probable causes of Demon Internet’s slow internet speed

Is it your Demon Internet internet connection that is running slow or is it your device (PC/laptop/phone)?

You need to check how many apps are running on your device.

The speed problem may be due to over-utilisation of your device’s resources e.g RAM/memory/CPU Processor and not an issue with Demon Internet’s broadband connection.

If you’re on a PC then you can use the task manager to check your CPU and Memory usage.

On any other device, you could try rebooting the device which hopefully should kill all applications that may be hogging system resources.

Re-run the Demon Internet Speed test on your computer and your mobile phone to check how the speed test results compare between the two devices.

Hopefully this should give you some info to work with in terms of whether the issue is with your device or the Demon Internet broadband connection.

Is the wireless the cause of the performance issue?

The root cause of the performance issue may be your Wi-Fi network and not the Demon Internet broadband connection.

You can rule out the Wifi by connecting your computer directly to the Demon Internet broadband router using a network cable and then run the Demon Internet Speed test again.

If the performance improves when you are connected by an ethernet cable, this suggests that the problem may be with your Wifi.

A few other things to check:

  • Are the WiFi channels that you’re using for your wireless network (SSID) overlapping with the neighbors?
  • Is your Wifi signal from the wireless router obstructed?
  • Does the speed get better when your are standing directly infront of the Demon Internet broadband router?

Who is connected to my Wifi network?

Have you checked that your Wi-Fi network password has not been hacked? Do you have an open Wi-Fi network? How strong is your Wi-Fi network password? It may be time to change it.

Others could be on your wireless network and eating up all your Demon Internet speed by downloading, uploading or even streaming music or videos over your Demon Internet broadband connection! Worse still, they may be carrying out illegal activities using your Demon Internet broadband connection.

There are 2 apps to use to scan your Wi-Fi network to check who is connected:

Both apps will scan your Wi-Fi network and show you a list of the devices connected.

Do I need a Wi-Fi network booster for my Demon Internet broadband?

You may discover that there are Wi-Fi black spots in your property, a wireless extender also known as a Wifi Booster is the best solution to increase your Wifi signal to cover any black spots.

The Wifi booster picks up the existing wireless network signal just as it is starting to become weaker and re-transmits the Wifi network signal to increase it’s reach.

Position the Wi-Fi network booster near where your Wifi signal from your Demon Internet internet router is starting to become weaker.

Position it approximately where your Wi-Fi network signal drops down to less than two bars. Walk around your house with a mobile phone to try and establih where this is.

When was the last time you upgraded the Demon Internet internet router?

The Demon Internet and broadband infrastructure, in general, are constantly updated to provide new features and improve reliability as technology evolves.  Ensure that the Demon Internet broadband router is running the most up to date software.

The majority of Demon Internet internet routers allow you to carry out the software upgrade by simply logging on the Demon Internet broadband router and simply clicking a button to perform the upgrade.

If you cannot do this, contact Demon Internet and they will be able to do this for you or alternatively, talk you through performing the upgrade yourself.

In addition to updating the software, if you have had the same router for a long period, it’s probably worth talking to Demon Internet to ask for a router upgrade.

Is the cause of the problem external to your home (at the exchange)?

This is probably the most common reason for Demon Internet broadband performance problems in your property and it’s more common for internet broadband connections that are delivered via copper phone lines.

If you’re unsure if this is relevant in your case, contact Demon Internet who will be able to conduct the relevant connection checks to check if there is a problem on the Demon Internet internet line.

Is it because of Demon Internet broadband congestion?

If you’re finding that the Demon Internet broadband connection speed in your area is slows down during certain periods e.g weekends and evenings, then it may be because of congestion during peak times.

You should contact Demon Internet to find out your guaranteed speed.
