Possible causes of John Lewis Broadband’s slow broadband performance

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

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

The speed problem could be due to over-utilization of your system resources i.e RAM/memory/CPU and not an issue with John Lewis Broadband’s internet connection.

If you are on a computer then you can use the task manager to check your Processor and Memory utilisation.

On any other device, you could try restarting the device which hopefully should shut down all programs that may have been using up your device resources.

Run the John Lewis Broadband Speed checker on your computer and your phone to check how the speed test results compare between the 2 devices.

This should hopefully give you some information to help determine whether the issue is with your PC/Smartphone or the John Lewis Broadband internet connection.

Is the Wifi the cause of the slowness?

The cause of the performance issue could be your Wi-Fi network and not the John Lewis Broadband internet connection.

You could rule out the Wifi by simply connecting your PC directly to the John Lewis Broadband broadband router using an ethernet cable and run the John Lewis Broadband Speed checker again.

If the speed is better when you’re connected via a network cable, this indicates that the issue could be with your Wi-Fi network.

Possible things to investigate:

• Are the Wireless channels that you are using for your Wifi network network (SSID) overlapping with the neighbours?
• Is your Wifi network signal from the internet router obstructed?
• Does your performance get better when your are stood right infront of the John Lewis Broadband wireless router?

Who’s connected to my wireless network?

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

Neighbours could be using your Wifi network and eating up all the John Lewis Broadband bandwidth by downloading, uploading or even streaming music or videos on your John Lewis Broadband broadband connection! Worse still, they may be conducting illegal activities over your John Lewis Broadband internet connection.

There are 3 applications that you can potentially utlise to analyse your Wifi network to check who is connected:

• WiFi scanning tool WiFi Analyzer

The above apps scan your wireless network and show you a list of the devices connected.

Should I get a wireless network booster for my John Lewis Broadband broadband?

If you find that there are Wifi coverage holes at your house, a wireless network extender also known as a Wi-Fi Booster may be the best solution to boost your Wi-Fi signal to cover any coverage gaps.

• Cheapest Wifi Signal Extenders

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

Place the Wifi network booster/extender near where your Wifi network signal from the John Lewis Broadband internet router is becoming weaker.

Place it approximately where your Wi-Fi network signal is dropping down to less than two bars. Walk around your property with a tablet to try and establish where this location is.
