Troubleshooting London Web internet performance issues

Before you start troubleshooting the performance of your London Web internet connection, we recommend that you run a London Web Broadband Speed Test to confirm your current broadband speed.

You can get this info by checking your London Web broadband bill, your London Web contract or by contacting London Web.
Potential causes of London Web’s slow internet performance
Is it your London Web internet connection that is slow or could it be your device (PC/laptop/phone)?
You may need to check the number of apps are running on your device.
The performance problem may be due to the over-utilisation of your system resources i.e Memory/CPU Processor and as opposed to an issue with London Web’s broadband connection.
If you’re on a PC then you can use the task manager to see your CPU and Memory usage.
On any other device, you should try restarting the device which hopefully will shutdown all programs that may have been hogging your systems resources.
Re-run the London Web Speed test on your personal computer and your mobile to check how the results compare between the two devices.
Hopefully this should give you some information to help determine if the problem lies with your device or the London Web internet connection.

Is the Wifi the reason for the issues?
The cause of the performance problem may be your internal Wifi network as opposed to the London Web broadband internet connection.
You could rule out the wireless network by connecting your PC directly to the London Web broadband router with an ethernet cable and then run the London Web Speed test again.
If the result is better when you’re connected via an ethernet cable, this proves that the problem could be with the Wi-Fi network.
A number of things to investigate:
- Are the Wireless channels that you’re using for your wireless network network (SSID) overlapping with the neighbors?
- Is your Wi-Fi network signal from the wireless router obstructed?
- Does your performance improve when your are stood directly infront of the London Web wireless router?
Who is connected to my wireless network?
Have you checked that your wireless network password has not been hacked? Do you have an un-secured wireless network? How secure is your wireless network password? It could be time to update it.
Others could be on your Wi-Fi network and using up all your London Web speed by downloading, uploading or even streaming music or videos on your London Web broadband connection! Worse still, they could be carrying out illegal activities over your London Web broadband connection.

There are three apps that you can utlise to analyse your Wi-Fi network to see who’s connected:
- Microsoft users can use Wireless network watcher
- Apple users can use whoFi (who is on my Wifi)
- WiFi troubleshooting tool WiFi Analyzer
The above apps scan your Wifi network and produce a list of the devices connected.
Do I need a Wifi network booster for my London Web broadband?
You may find that there are Wifi coverage holes in your home, a Wifi network extender aka a Wi-Fi Booster may be the best fix to strengthen your wireless signal to cover any coverage holes.
The wireless booster simply picks up the existing wireless signal just as it is becoming weaker and re-transmits the Wifi network signal to extend it’s coverage.
Position the wireless network booster near the position where your wireless network signal from your London Web broadband router is becoming weaker.
Place it approximately where your Wi-Fi network signal is dropping down to less than 2 bars. Walk around your house with a mobile phone to find where this is.
When was the last time you upgraded the London Web internet router?

The London Web and broadband infrastructure, in general, are constantly upgraded to support new features and improve performance as technology evolves. Always ensure that the London Web internet router is running on the latest software.
Most London Web internet routers allow you to perform the software upgrade by simply logging on the London Web broadband router and simply clicking a button to start the update.
If you cannot do this, get in touch with London Web and they will do this for you or talk you through the process.
In addition to upgrading the software, if you have had router for a long time, it may be worth speaking to London Web to request for a hardware upgrade.
Is the fault outside your property (at the exchange)?
This is probably the most likely cause for London Web broadband performance issues in your area and it’s more common for broadband connections that are delivered using copper phone lines.
If you’re unsure if this is relevant in your case, you should contact London Web who should be able to carry out the appropriate line tests to see if there is a fault on the London Web broadband connection.
Is it because of London Web broadband congestion?
If you are finding that the London Web broadband connection speed in your area is slows down during certain periods e.g over weekends or during the evening, then it may be due to congestion during peak hours.
You should contact London Web to check your guaranteed speed.
