Is my VPN slowing my connection down?

It could be. Make sure your VPN is turned off when you don’t need it. VPNs can slow your connection down.

Recommended Speed Test Services

Should I use a cabled connection when carrying out a speed test?

Speed tests are best carried out over a hardwired connection as the results will be more accurate than a wireless speed test. If you are unable to test with a cable connection, please use a Wi-Fi device that is up to date and has 5Ghz capability if possible.  


How do I complete a cabled broadband speed test?

  1. Connect your device directly to one of the ethernet ports on your router with an ethernet cable (Cat5e standard or above) 
  1. Go to one of the above speed test servers in your web browser 
  1. Ensure that the ‘Lothian Broadband Networks Limited, Edinburgh’ server is selected. If it is not, then select it from the drop-down list 
  1. Click ‘Go’ 

    Tip – make sure that no device on the network is using large amounts of data while carrying out speed tests as this can show a speed test that is slower than reality 

What do I do if I cannot run a cabled test?

If your device doesn’t have an ethernet port, then you can still test using Wi-Fi. However, the results will not be as accurate as Wi-Fi signal interruptions can affect the speed/quality of internet speed you receive on your device.  

How do I run a Wi-Fi speed test?

  1. Please ensure the device you are using to test from is close to the main router and no more than 1 metre away 
  1. Go to one of the above speed test servers in your web browser 
  1. Ensure that the ‘Lothian Broadband Networks Limited, Edinburgh’ server is selected. If it is not, then select it from the drop-down list 
  1. Click ‘Go’ 

    Tip – Ensure that no other devices are connected to the network a the time of running a Wi-Fi speed test in order to receive a more accurate test result.  

What do the results mean?


Ping is the reaction time of your connection (how quickly you get a response after you’ve sent out a request). A fast ping means a more responsive connection, especially in applications where timing is key such as video conferencing and gaming. Anything under 59ms is great – lower ping the better!  


Download Speed 

The download speed is how fast you can pull data from the server to you. Most connections are designed to download much faster than they upload, since the majority of online activity, such as loading web pages or streaming videos, consists of data downloads. Download speed is measured in megabits per second (Mbps).  


Upload Speed 

The upload speed is how fast you send data from you to others. Uploading is necessary for sending big files via email, using video calls to talk to someone else and online gaming. Upload speed is also measured in megabits per second (Mbps).  


What does all this mean?

Many factors can impact a speed test result. It is always good to do multiple speed tests over a period of time using a different device if you can. This can help narrow down any issues to a particular device or connection.  


All devices have different capabilities, and some may not be able to measure the full speeds of your broadband service. Your test result will only be as fast as the slowest part of the connection between your device and the speed test server.  

Wired or Wireless 

How the test is carried out will make a huge difference. Always test using a wired connection first if possible.  


Not all ethernet cables are capable of carrying the full speeds of your broadband service. Cat5 can carry 100Mbps, Cat5e can carry 1000Mbps and Cat6 can carry 1000Mbps +. 


A speed test measures the connection at that point in time and will vary based on what is happening at that time, both on the device and within the home. More devices on the network in your means more devices sharing the internet connection. This will affect the speed any single device can achieve. If the device is occupied doing something at the same as the speed test, it will react slower to the speed test giving a lower speed than is actually available.  

Your Device  

Mobile device test results will usually be different than tests using a computer or laptop due to the hardware processing limitations and may provide lower results than your broadband service speed. As an example, the Apple iPhone 6 has a maximum Wi-Fi connection speed of up to 120Mbps whereas recent laptop and desktop computers can achieve up to 1Gbps via a wired connection.
