Troubleshooting 4theNET internet speed issues

Before you begin troubleshooting the speed of your 4theNET internet connection, we suggest that you perform a 4theNET Internet Speed Test to measure your current connection speed.
You may also want to find out the guaranteed minimum download speed you on your broadband package from 4theNET.
You can get this information by checking your 4theNET broadband bill, your 4theNET contract or by contacting 4theNET.
Probable causes of 4theNET’s slow broadband speed
Is it your 4theNET internet connection that is slow or is it your device (PC/laptop/phone)?
You may need to consider how many apps are currently running on your device.
The performance issue could be due to over-utilisation of your system resources e.g Memory/CPU Processor and as opposed to a problem with 4theNET’s broadband connection.
If you’re on a PC then you can use the task manager to check your CPU and Memory utilisation.
On other device, you should try rebooting the device which should hopefully shutdown all apps that may be hogging your systems resources.
Run the 4theNET Speed checker on your PC and your mobile phone to see how the results differ between the 2 devices.
Hopefully this should give you some info to work with in terms of if the problem is with your device or the 4theNET broadband connection.

Is the Wifi the reason for the issues?
The cause of the performance issue may be your wireless as opposed to the 4theNET broadband internet connection.
You can rule out the wireless network by connecting your computer directly to the 4theNET broadband router with a network cable and run the 4theNET Speed checker again.
If the result is better when you’re connected by an ethernet cable, this suggests that the problem could be with your wireless network.
A few other things to look further into:
- Are the Wireless channels that you are using for your wireless network (SSID) overlapping with your neighbors?
- Is the wireless network signal from the wireless router obstructed?
- Does the speed get better when your are stood directly in-front of the 4theNET wireless router?
Who is connected to my Wifi network?
Have you checked that your Wi-Fi network password has not been hacked? Do you have an open Wifi network? How strong is your Wifi network password? It may be time to update it.
Neighbours could be on your wireless network and using up all the 4theNET speed by downloading, uploading or even streaming music or videos over your 4theNET internet connection! Worse than that, they may be carrying out illegal activities over your 4theNET broadband connection.

Here are 3 applications to utlise to scan your Wi-Fi network to check who’s connected:
- Microsoft Windows users can use Wireless network watcher
- IOS users can use whoFi (who is on my Wifi)
- wifi network scanning application WiFi Analyzer
The above apps analyse your Wi-Fi network and show you a list of the everything on your wifi.
Do I need a wireless booster for my 4theNET broadband?
If you discover that there are Wi-Fi black holes in your home, a wireless network extender also known as a Wifi Booster may be the best solution to increase your Wifi signal to cover any coverage holes.
The Wifi extender picks up your existing wireless signal just as it is starting to become weaker and re-transmits the Wifi signal to extend it’s coverage.
Place the Wifi booster near the position where your wireless signal from the 4theNET broadband router is becoming weaker.
Position it near where your Wifi network signal is dropping down to less than two signal bars. Walk around your house with a mobile phone to determine where this location is.
When did you last upgrade the 4theNET broadband router?

The 4theNET and broadband infrastructure, in general, are frequently upgraded to support new features and improve reliability as technology evolves. Always ensure that your 4theNET internet router is running on the most up-to-date software.
Most 4theNET broadband routers allow you to carry out the software upgrade by simply logging into the 4theNET broadband router and simply clicking on a button to start the update.
If you can’t do this, get in touch with 4theNET and they will be able to perform the upgrade for you or alternatively, guide you through performing the upgrade yourself.
As well as upgrading the software, if you have had the same router for a long period, it is worth speaking to 4theNET to ask for a router upgrade.
Is the fault outside your property (at the exchange)?
This is probably the most likely reason for 4theNET broadband performance problems in your area and is more common with internet broadband connections that are delivered via phone lines.
If you’re not sure if this is relevant in your case, you should contact 4theNET who will be able to run the appropriate connection checks to check if there is a problem on the 4theNET broadband connection.
Is it because of 4theNET broadband congestion?
If you are finding that the 4theNET internet connection speed in your area is slows down during certain times i.e. over weekends or evenings, then it may be due to congestion during peak times.
You should contact 4theNET to find out your guaranteed speed.
