How to troubleshoot Zen Internet broadband speed problems

Before starting to troubleshoot the performance of your Zen Internet broadband connection, we suggest that you perform a Zen Internet Internet Speedtest to measure your current broadband speed.

You can get this info by checking a Zen Internet broadband bill, your Zen Internet contract or by contacting Zen Internet.
Potential causes of Zen Internet’s slow internet performance
Is it the Zen Internet internet connection that is running slow or could it be your device (PC/laptop/phone)?
You may need to consider the number of applications are running on your device.
The performance problem could be due to over-utilisation of your system resources e.g RAM/memory/CPU Processor and not an issue with Zen Internet’s broadband connection.
If you’re on a laptop then you may 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 apps that may be hogging system resources.
Re-run the Zen Internet Speed checker on your PC and your mobile phone to see how the speed test results differ between the 2 devices.
This should hopefully provide you with some information to work with in terms of if the issue is with your PC/Smartphone or the Zen Internet internet connection.

Is your wireless network the reason for the issues?
The cause of the performance issue could be your Wifi network and not the Zen Internet broadband internet connection.
You could rule out the wireless network by simply connecting your PC directly to the Zen Internet broadband router with a network cable and run the Zen Internet Speed test again.
If the speed improves when you’re connected by a network cable, this suggests that the problem could be with the Wifi network.
Possible things to investigate:
- Are the Wireless channels that you are using for your wireless network network (SSID) overlapping with your neighbours?
- Is the wireless network signal from the wireless router obstructed?
- Does your speed improve when your are stood right in-front of the Zen Internet broadband router?
Who is connected to my wireless network?
Have you checked that your Wi-Fi network password has not been shared? Do you have an un-secured wireless network? How complex is your wireless network password? It could be time to update it.
Neighbours could be on your Wifi network and using up all the Zen Internet bandwidth by downloading, uploading or even streaming music or videos on your Zen Internet internet connection! Worse still, they may be conducting illegal activities using your Zen Internet internet connection.

There are three applications that you can potentially utlise to analyse your Wi-Fi network to see who is 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 software will scan your wireless network and display a list of the connected devices.
Should I get a Wi-Fi network booster for my Zen Internet broadband?
You may find that you have Wi-Fi black holes in your house, a Wi-Fi network extender aka a wireless Booster may be the best fix to boost your Wifi signal to cover any black spots.
The wireless booster simply picks up the existing Wifi signal as it is becoming weaker and re-transmits the wireless network signal to increase it’s coverage.
Position the Wifi network extender where your Wifi network signal from the Zen Internet broadband router is starting to become weaker.
Place it near where your Wifi network signal is dropping down to two signal bars. Walk around your home with a mobile phone to determine where this is.
When did you last upgrade the Zen Internet broadband router?

The Zen Internet and broadband infrastructure, in general, are constantly updated to provide new features and improve performance as technology evolves. Ensure that the Zen Internet broadband internet router is running on the most up to date software.
Most Zen Internet broadband routers allow you to perform the software upgrade by logging into the Zen Internet broadband router and simply clicking a button to perform the update.
If you can’t do this, get in touch with Zen Internet and they will be able to perform the upgrade for you or talk you through performing the upgrade yourself.
As well as updating the software, if you have had hardware for a long period, it’s probably worth speaking to Zen Internet to ask for a hardware upgrade.
Is the root cause of the issue external to your home (at the exchange)?
This is probably the most common reason for Zen Internet broadband performance issues in your area and is more common with broadband connections that are delivered using copper phone lines.
If you are unsure if this is applicable to you, you should contact Zen Internet who will be able to run the relevant line checks to check if there is a fault on the Zen Internet internet connection.
Is it due to Zen Internet broadband congestion?
If you’re finding that the Zen Internet internet connection speed in your area is slow during certain periods i.e. weekends and evenings, it may be due to congestion during peak hours.
You should speak to Zen Internet to check your minimum speed.
