How to troubleshoot Demon Internet internet speed issues

Before you start troubleshooting the performance of your Demon Internet internet connection, we recommend that you perform a Demon Internet Internet Speed Test to benchmark your current internet speed.

It is a good idea to also confirm the guaranteed minimum download speed you on your broadband package from Demon Internet.

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

Likely causes of Demon Internet’s slow internet speed

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

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

The speed issue could be due to over-utilisation of your device’s resources e.g RAM/CPU 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 Memory utilisation.

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

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

This should hopefully give you some info to help determine if the issue is with your PC/Smartphone or the Demon Internet internet connection.

Is your Wifi network the cause of the issue?

The root cause of the performance problem may be your internal Wifi network as opposed to the Demon Internet internet connection.

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

If the result is better when you’re connected via a network cable, this shows that the issue may be with your Wifi network.

A few other things to check:

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

Who’s connected to my Wi-Fi 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 Wi-Fi network password? It may be time to change it.

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

There are three apps that you can use to analyse your Wi-Fi network to check who is connected:

• Windows users can use Wireless network watcher
• MAC users can use whoFi (who is on my Wifi)
• wireless network scanning tool WiFi Analyzer

The above applications scan your Wifi network and display a list of the everything on your wifi.

Do I need a wireless network booster for my Demon Internet broadband?

If you discover that there are Wifi black holes at your property, a wireless extender aka a Wifi Booster may be the best solution to strengthen your Wifi signal to cover any black holes.

• Best Wifi Signal Extenders

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

Position the Wifi network booster where your wireless network signal from the Demon Internet internet router is starting to become weaker.

Place it approximately where your Wifi signal drops down to 2 bars. Walk around your property with a mobile phone to find where this is.

When did you last upgrade the Demon Internet broadband router?

The Demon Internet and broadband infrastructure, in general, are constantly upgraded to support new features and improve performance as technology evolves.  Ensure that your Demon Internet broadband internet router is running on the latest software.

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

If you can’t do this, get in touch with Demon Internet and they will be able to perform the upgrade for you or alternatively, guide you through performing the upgrade yourself.

In addition to upgrading the software, if you have had the same router for a long time, it may be worth talking to Demon Internet to request for a router upgrade.

Is the root cause of the issue outside your property (at the exchange)?

This is probably the most likely reason for Demon Internet broadband performance problems in your home and is more common for broadband connections that are delivered through phone lines.

If you’re not sure if this is relevant in your case, you should contact Demon Internet who will be able to run the appropriate connection checks to check if there is a fault on the Demon Internet internet line.

Is the issue due to Demon Internet Internet congestion?

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