Troubleshooting C4L internet speed issues

C4L Internet speedtest - Slow broadband speed

Before you begin troubleshooting the performance of your C4L internet connection, we recommend that you run a C4L Internet Speedtest to confirm your current connection speed.

It is a good idea to also find out the guaranteed minimum download speed you on your broadband package from C4L.

You can get this information by checking your C4L broadband bill, your C4L contract or by contacting C4L.

Possible causes of C4L’s slow broadband speed

Is it the C4L internet connection that is slow or could it be your device (laptop/smartphone/PC)?

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

The speed problem may be due to over-utilization of your device’s resources i.e Memory/CPU and not an issue with C4L’s broadband connection.

If you are on a laptop then you can use the task manager to see your Processor and RAM utilisation.

On any other device, you should try rebooting the device which hopefully should shut down all applications that may have been using up system resources.

Run the C4L Speed test on your PC and your mobile phone to check how the speed test results differ between the two devices.

This should hopefully give you some information to help determine whether the issue lies with your PC/Smartphone or the C4L internet connection.

Is your Wifi the cause of the issue?

The cause of the performance issue could be your internal Wifi network and not the C4L internet connection.

You could rule out the Wifi network by connecting your computer directly to the C4L broadband router using a network cable and then run the C4L Speed checker again.

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

A number of things to check:

  • Are the Wireless channels that you are using for your wireless network (SSID) overlapping with your neighbors?
  • Is your wireless network signal from the internet router obstructed?
  • Does the performance get better when you’re stood right in-front of the C4L broadband router?

Exactly who’s connected to my Wi-Fi network?

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

Others could be on your Wifi network and using up all the C4L bandwidth by downloading, uploading or even streaming music or videos over your C4L broadband connection! Worse still, they could be conducting illegal activities over your C4L broadband connection.

There are two applications that you can use to scan your wireless network to check who is connected:

Both applications scan your Wi-Fi network and display a list of the devices connected.

Do I need a wireless network booster for my C4L broadband?

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

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

Position the Wi-Fi network booster/extender where your Wifi network signal from the C4L broadband router is starting to become weaker.

Place it approximately where your wireless signal drops down to less than 2 bars. Walk around your house with a smartphone to find where this location is.

When was the last time you upgraded the C4L broadband router?

The C4L and broadband infrastructure, in general, are frequently upgraded to provide new features and improve performance as technology evolves.  Always ensure that the C4L broadband internet router is running on the most up-to-date software.

Most C4L broadband routers will allow you to perform the software update by simply logging into the C4L broadband router and simply clicking on a button to start the update.

If you can’t do this, contact C4L and they will be able to perform the upgrade for you or guide you through the process.

As well as upgrading the software, if you have had router for a long time, it’s worth speaking to C4L to request for a router upgrade.

Is the fault external to your home (at the exchange)?

This is probably the most likely reason for C4L broadband performance problems in your area and it’s more common for internet broadband connections that are delivered through phone lines.

If you are not sure if this is applicable to you, contact C4L who should be able to carry out the appropriate connection tests to see if there is a problem on the C4L broadband connection.

Is it because of C4L broadband congestion?

If you are finding that the C4L broadband connection speed in your area is slows down during certain periods i.e. over weekends and evenings, then it may be due to congestion during peak times.

You should contact C4L to find out your minimum speed.

Re-testing your C4L internet connection

After the fault has been fixed either by yourself or C4L, re-test the internet connection using  at least two separate Speedtests to ensure the fault is fixed:
