How to troubleshoot Diamond Net broadband performance problems

It is also a good idea confirm the guaranteed minimum download speed that you on your broadband package from Diamond Net.

Potential causes of Diamond Net’s slow internet performance
Is it the Diamond Net internet connection that is running slow or could it be your device (laptop/smartphone/PC)?
You need to consider the number of apps are running on your device.
The performance problem could be due to over-utilization of your system resources i.e RAM/memory/CPU Processor and not an issue with Diamond Net’s internet connection.
If you are on a computer then you can use the task manager to check your Processor and RAM utilization.
On any other device, you should try rebooting the device which hopefully should shutdown all applications that may be using up system resources.
Re-run the Diamond Net Speed checker on your PC and your phone to check how the speed test results compare between the two devices.
This should hopefully give you some information to help determine if the problem is with your device or the Diamond Net internet connection.

Is your wireless network the problem?
The root cause of the performance issue may be your Wifi network as opposed to the Diamond Net broadband internet connection.
You can rule out the Wi-Fi network by simply connecting your computer directly into the Diamond Net broadband router with a network cable and then run the Diamond Net Speed checker again.
If the speed checker result is better when you are connected by an ethernet cable, this shows that the issue may be with the Wi-Fi network.
A few other things to investigate:
- Are the WiFi channels that you are using for your Wi-Fi network network (SSID) overlapping with your neighbours?
- Is the Wifi signal from the internet router obstructed?
- Does the performance improve when you’re standing directly in-front of the Diamond Net internet router?
Exactly who’s connected to my Wi-Fi network?
Have you checked that your wireless network password has not been hacked? Do you have an open wireless network? How complex is your wireless network password? It could be time to update it.
Neighbours could be using your Wifi network and using up all your Diamond Net speed by downloading, uploading or even streaming music or video on your Diamond Net internet connection! Worse still, they could be conducting illegal activities on your Diamond Net broadband connection.

Here are 3 apps that you can utlise to scan your wireless network to see who’s connected:
- Windows users can use Wireless network watcher
- IOS users can use whoFi (who is on my Wifi)
- Wireless troubleshooting application WiFi Analyzer
The above apps scan your Wifi network and show you a list of the connected devices.
Should I get a Wifi booster for my Diamond Net broadband?
If you find that there are wireless black holes in your property, a Wifi extender also known as a wireless Booster is the best fix to boost your Wi-Fi signal to cover any coverage gaps.
The wireless network booster picks up your existing Wifi signal just as it is starting to become weaker and re-transmits the wireless network signal to extend it’s reach.
Position the Wi-Fi network booster/extender near where your Wifi network signal from the Diamond Net internet router is becoming weaker.
Place it approximately where your Wifi signal is dropping down to less than 2 bars. Walk around your property with a smartphone to find where this location is.
When was the last time you upgraded the Diamond Net internet router?

The Diamond Net and broadband infrastructure, in general, are constantly upgraded to support new features and improve reliability as technology evolves. Ensure that your Diamond Net internet router is running the most up-to-date software.
The majority of Diamond Net internet routers allow you to perform the software update by simply logging into the Diamond Net broadband router and simply clicking a button to perform the upgrade.
If you can’t do this, get in touch with Diamond Net 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 hardware for a long time, it may be worth speaking to Diamond Net to request for a router upgrade.
Is the fault external to your home (at the exchange)?
This is probably the most common cause for Diamond Net broadband performance problems in your area and it’s more common for internet broadband connections that are delivered via phone lines.
If you’re unsure if this is applicable to you, contact Diamond Net who will be able to conduct the relevant line checks to check if there is a fault on the Diamond Net broadband connection.
Is the performance issue because of Diamond Net broadband congestion?
If you’re finding that the Diamond Net internet connection speed in your area is slow during certain times i.e. weekends or during the evening, it may be due to congestion during peak times.
You should contact Diamond Net to find out your minimum speed.
