How to troubleshoot Demon Internet internet speed problems

Demon Internet Internet speedtest - Slow Internet speed

Before you start troubleshooting the speed of your Demon Internet internet connection, we suggest that you run a Demon Internet Broadband Speed Test to confirm your current internet speed.

Also find out the minimum download speed you are paying for from Demon Internet.

You can find 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 broadband speed

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

You need to consider how many applications are running on your device.

The performance issue may be due to the over-utilization of your system resources i.e RAM/memory/CPU Processor and not an issue with Demon Internet’s broadband connection.

If you’re on a laptop then you may use the task manager to see your CPU and RAM usage.

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

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

Hopefully this should give you more information to help determine if the issue lies with your PC/Smartphone or the Demon Internet broadband connection.

Is your Wi-Fi network the reason for the issues?

The cause of the performance issue could be your Wifi and not the Demon Internet internet connection.

You can rule out the Wifi network by connecting your computer directly to the Demon Internet broadband router with an ethernet cable and then run the Demon Internet Speedtest again.

If the performance improves when you’re connected using an ethernet cable, this indicates that the problem could be with your Wi-Fi network.

A number of things to look further into:

  • Are the WiFi channels that you are using for your Wi-Fi network network (SSID) overlapping with your neighbours?
  • Is the Wi-Fi network signal from the internet router obstructed?
  • Does your performance improve when your are standing directly infront of the Demon Internet internet router?

Who’s connected to my wireless network?

Have you checked that your Wifi network password has not been compromised? Do you have an un-secured wireless network? How secure is your Wifi network password? It could be time to update it.

Others could be using your wireless network and using up all your Demon Internet bandwidth by downloading, uploading or even streaming music or video over your Demon Internet broadband connection! Worse than that, they could be conducting illegal activities on your Demon Internet broadband connection.

There are two apps that you can use to scan your wireless network to see who’s connected:

Both applications scan your wireless network and show you a list of the connected devices.

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

You may find that you have Wifi black holes in your house, a Wifi extender aka a wireless Booster may be the best fix to strengthen your Wifi signal to cover any black spots.

The Wi-Fi network extender simply picks up the existing wireless signal just as it is starting to become weaker and re-transmits the wireless signal to extend it’s reach.

Place the Wi-Fi network booster/extender near the position where your wireless network signal from your Demon Internet internet router is starting to become weaker.

Place it approximately where your wireless signal drops down to less than two signal bars. Walk around your property with a smartphone to determine where this location is.

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

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

Most Demon Internet internet routers will allow you to perform the software upgrade by simply logging into the Demon Internet broadband router and simply clicking a button to perform the update.

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

In addition to updating the software, if you have had hardware for a long period, it may be worth talking to Demon Internet to ask for a hardware upgrade.

Is the fault outside your property (at the exchange)?

This is probably the most common cause for Demon Internet broadband performance issues in your area and is more common with broadband connections that are delivered using phone lines.

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

Is the performance issue due to Demon Internet Internet congestion?

If you are finding that the Demon Internet broadband connection speed in your area is slows down during certain periods e.g over weekends or during the evening, it may be because of congestion during peak times.

You should contact Demon Internet to check your guaranteed speed.

Re-testing your Demon Internet internet connection

After the issue has been resolved either by yourself or Demon Internet, re-test your internet connection using  at least two separate Speedtests to ensure the problem is resolved:
