How to troubleshoot Fast4 broadband internet speed

Fast4 Internet speedtest - Slow broadband speedBefore starting to troubleshoot the speed of your Fast4 internet connection, you need to run the Fast4 Internet Broadband Speed Test and also confirm what Upload and Download speed you are paying for.

You can get this info by checking a Fast4 bill or contact Fast4 to confirm this info.

Likely causes of Fast4 slow internet speed

Is it your Fast4 broadband that is slow or is it your device (PC/laptop/phone)?

You need to consider how many apps are currently running on your device that could be utilising your system resources (mainly RAM memory and CPU) and/or your Fast4 internet bandwidth.

If you are on a computer then you may use the task manager to see your CPU and memory usage.

On any other device you should try rebooting the device which should hopefully shutdown all programs that may have been running in the background.

Re-run the Fast4 speed test on your PC and your phone to see how the speedtest results compare between the two devices.

This should hopefully give you some info to work with in terms of whether the issue lies with your device or the Fast4 internet connection.

Is your Wifi network connection the problem?

The cause of the issue could be your Wi-Fi network connection and not the Fast4 broadband internet connection.

You can rule out the wireless network being the cause of the issue by connecting your computer directly to the Fast4 broadband router using an ethernet cable and run the Fast4 speedtest again.

If performance is better when you’re connected via an ethernet cable then this proves that the problem could be with your Wi-Fi network connection setup.

Possible things to investigate are:

  • Are the WiFi channels you are using for your wireless network (SSID) overlapping with the neighbors?
  • Could your wireless network signal from the router be obstructed?
  • Does the performance improve when your are standing directly in-front of the Fast4 broadband or wireless router?

Who is connected to my Wi-Fi network?

Have you checked that your wireless network password has not been compromised? Do you have an un-secured Guest wireless network?

Neighbors could be on your Wifii network and eating up all your Fast4 bandwidth downloading/uploading or even streaming netflix! Worse than that, they could be carrying out illegal activities which will all point to your connection.

There are 2 applications that you can use to scan your Wifi network to see who’s connected:

Both applications will scan your Wifi network and display a list of the connected devices.

Check out this tutorial on how to use both applications

Do I need a Wifi Booster for my Fast4 broadband?

If you find that you have Wi-Fi black holes in your house, then a Wifi extender aka a Wifi Booster is the fix to boost your signal. They are readily available online from around £15.

The Wifi network booster simply picks up the existing wireless signal as it is becoming weak and then re-transmits the wireless network signal at a more stronger rate to extend it’s coverage.

Place the Wifi network booster/extender where your Wifi network signal from the Fast4 broadband router is becoming weak.  Approxiametly where your wireless signal drops down to 2 bars. Use your mobile phone to determine where this is.

When was the last time you upgraded your Fast4 broadband router?

The Fast4 and openreach infrastructure is constantly being upgraded to support new features (some customer facing and others internal).  Ensure that the Fast4 broadband router has the latest software.

The majority of Fast4 broadband routers will allow you to perform the software upgrade by logging into the Fast4 broadband router and simply clicking a button to perform the update.

If you cannot do this, contact Fast4 and they will be able to either do this for you or guide you through how to do it depending on the Fast4 router model you have.

As well as updating the software, if you have had the same router for a long period, it is worth talking to Fast4 to request for a router upgrade.

Is the fault external (at the exchange)?

This is probably the most common reason for Fast4 broadband performance issue in your home and it’s more common with broadband connections that are delivered through phone lines.

If you are not sure if this is applicable to you, you should contact Fast4 who should be able to run the relevant connection tests to check if there is a issue on the Fast4 internet connection.

Is it due to Fast4 Broadband congestion?

If you are finding that the Fast4 internet connection speed in your area is slow during certain times i.e. over weekends and during the evening, it may be due to congestion during peak times.

You should speak to your Fast4 to find out if the service you subscribed to has a guaranteed speed or is  a contended ‘first come first serve’ service with no minimum speed guaranteed.

Re-testing your Fast4 broadband connection

After the problem has been resolved either by yourself or Fast4, re-test the internet connection using  at least 2 independent speedtests such as the one here and Ookla broadband speedtester to ensure the fault is fixed.
