Troubleshooting Fast4 broadband performance problems

Fast4 Internet speed test - Slow Internet speed

Before you start troubleshooting the speed of your Fast4 broadband connection, we suggest that you run a Fast4 Broadband Speedtest to benchmark your current connection speed.

It is a good idea to also find out the guaranteed minimum download speed that you are paying for from Fast4.

You can find this information by checking a Fast4 broadband bill, your Fast4 contract or by contacting Fast4.

Common causes of Fast4’s slow internet speed

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

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

The performance issue may be due to over utilization of your system resources i.e Memory/CPU and as opposed to an problem with Fast4’s broadband connection.

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

On other device, you should try rebooting the device which should hopefully shut down all applications that may be using up your systems resources.

Run the Fast4 Speed checker on your personal computer and your mobile phone to see how the results compare between the 2 devices.

Hopefully this should provide you with some info to work with in terms of whether the issue lies with your PC/Smartphone or the Fast4 broadband connection.

Is the Wifi network the problem?

The cause of the performance problem could be your wireless as opposed to the Fast4 internet connection.

You can rule out the wireless by connecting your computer directly into the Fast4 broadband router with a network cable and run the Fast4 Speed checker again.

If the speed checker result improves when you are connected by an ethernet cable, this shows that the problem could be with your wireless network.

A few other things to check:

  • Are the WiFi channels that you’re using for your wireless network (SSID) overlapping with the neighbors?
  • Is the Wi-Fi network signal from the wireless router obstructed?
  • Does the performance improve when your are stood directly in-front of the Fast4 wireless 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 open wireless network? How complex is your Wifi network password? It could be time to update it.

Others could be on your wirelessi network and using up all your Fast4 bandwidth by downloading, uploading or even streaming music or video over your Fast4 broadband connection! Worse still, they may be carrying out illegal activities using your Fast4 internet connection.

Here are two applications that you can use to scan your Wi-Fi network to see who’s connected:

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

Do I need a Wifi booster for my Fast4 broadband?

You may find that you have Wi-Fi black holes at your property, a Wifi extender also know as a Wi-Fi Booster may be the best solution to strengthen your Wifi signal to cover any black spots.

The Wifi booster simply picks up the existing Wifi signal as it is becoming weaker and re-transmits the Wifi signal to extend it’s reach.

Position the wireless network booster/extender where your Wifi signal from the Fast4 broadband router is starting to become weaker.

Position it near where your Wifi network signal is dropping down to 2 bars. Walk around your house with a tablet to find where this is.

When did you last upgrade the Fast4 internet router?

The Fast4 and broadband infrastructure in general are frequently updated to support new features and improve performance as technology evolves.  Always ensure that your Fast4 broadband internet router is running on the most up to date software.

The majority of Fast4 internet routers will allow you to carry out the software update by logging into the Fast4 broadband router and simply clicking on a button to do the update.

If you cannot do this, get in touch with Fast4 and they will be able to perform the upgrade for you or alternatively, talk you through performing the upgrade yourself.

In addition to updating the software, if you have had the same hardware for a long period, it’s worth talking to Fast4 to request for a router upgrade.

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

This is probably the most likely cause for Fast4 broadband performance problem in your home and is more common for internet broadband connections that are delivered using 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 line checks to check if there is a problem on the Fast4 internet line.

Is it because of Fast4 broadband congestion?

If you’re finding that the Fast4 broadband connection speed in your area is slow during certain periods i.e. weekends and evenings, then it may be because of congestion during peak hours.

You should speak to Fast4 to check your minimum speed.
