Troubleshooting CLANNET broadband speed problems

Before starting to troubleshoot the speed of your CLANNET broadband connection, we recommend that you run a CLANNET Internet Speed Test to confirm your current broadband speed.
Also confirm the guaranteed minimum download speed that you are paying for from CLANNET.
You can find this information by checking a CLANNET broadband bill, your CLANNET contract or by contacting CLANNET.
Likely causes of CLANNET’s slow broadband speed
Is it your CLANNET internet connection that is slow or is it your device (PC/laptop/phone)?
You need to check the number of applications are currently running on your device.
The speed problem could be due to over-utilization of your device’s resources e.g RAM/memory/CPU Processor and as opposed to an issue with CLANNET’s internet connection.
If you’re on a PC then you may use the task manager to see your Processor and RAM usage.
On other device, you could try restarting the device which hopefully will terminate all apps that may have been hogging system resources.
Re-run the CLANNET Speedtest on your personal computer and your mobile to see how the results compare between the 2 devices.
This should hopefully provide you with more information to help determine if the issue is with your PC/Smartphone or the CLANNET internet connection.

Is your wireless network the reason for the issues?
The cause of the performance issue may be your internal Wifi network as opposed to the CLANNET internet connection.
You could rule out the Wifi by simply connecting your computer directly to the CLANNET broadband router using a network cable and run the CLANNET Speed test again.
If the speed is better when you are connected using an ethernet cable, this shows that the problem may be with your Wi-Fi network.
A few other things to look further into:
- Are the Wireless channels that you’re using for your Wifi network (SSID) overlapping with your neighbors?
- Is your wireless network signal from the internet router obstructed?
- Does your performance improve when your are stood directly in-front of the CLANNET broadband 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 un-secured wireless network? How strong is your Wifi network password? It may be time to change it.
Others could be on your Wi-Fi network and eating up all the CLANNET bandwidth by downloading, uploading or even streaming music or videos over your CLANNET internet connection! Worse still, they may be carrying out illegal activities over your CLANNET broadband connection.

Here are 3 apps to utlise to scan your Wifi network to see who is connected:
- Microsoft users can use Wireless network watcher
- IOS users can use whoFi (who is on my Wifi)
- wifi network troubleshooting application WiFi Analyzer
The above apps analyse your Wi-Fi network and show you a list of the everything on your wifi.
Should I get a wireless booster for my CLANNET broadband?
You may discover that there are Wifi black spots at your home, a Wifi extender also known as a Wifi Booster is the best solution to strengthen your wireless signal to cover any coverage gaps.
The wireless booster picks up the existing wireless network signal as it is becoming weaker and re-transmits the Wi-Fi network signal to extend it’s reach.
Place the Wi-Fi network booster where your Wifi network signal from the CLANNET broadband router is starting to become weaker.
Position it near where your Wifi signal is dropping down to less than 2 signal bars. Walk around your house with a tablet to find where this location is.
When did you last upgrade the CLANNET broadband router?

The CLANNET and broadband infrastructure, in general, are frequently upgraded to support new features and improve performance as technology evolves. Ensure that the CLANNET internet router is running on the most up to date software.
The majority of CLANNET broadband routers will allow you to carry out the software update by logging into the CLANNET broadband router and simply clicking on a button to start the update.
If you cannot do this, get in touch with CLANNET and they will be able to perform the upgrade for you or alternatively, talk you through performing the upgrade yourself.
As well as updating the software, if you have had the same router for a long time, it’s worth talking to CLANNET to ask for a router upgrade.
Is the problem external to your home (at the exchange)?
This is probably the most likely cause for CLANNET broadband performance problems in your home and is more common for broadband connections that are delivered via phone lines.
If you’re not sure if this is applicable to you, you should contact CLANNET who will be able to conduct the appropriate connection tests to check if there is a fault on the CLANNET internet line.
Is the issue because of CLANNET Internet congestion?
If you’re finding that the CLANNET internet connection speed in your area is slow during certain times e.g weekends and during the evening, then it may be due to congestion during peak hours.
You should speak to CLANNET to find out your guaranteed speed.
