Find information below on troubleshooting your CRISP NBN Service, how to improve your Wifi Speeds and get information on NBN Outages or service disruptions.

 Check connection at your end if you have slow internet service.


Correct plan speed:

Ensure you select the plan that fits your needs. If the speed test indicates that your typical evening speed matches what's advertised in our plans, it may be time to consider upgrading your plan.

Network Congestion:

During peak usage hours, internet speeds may slow down due to increased demand. Consider using the internet during non-peak hours.

Wi-Fi Signal Strength:

If you are using Wi-Fi, check your signal strength. Walls and obstacles can weaken the signal. Move closer to the router or use a Wi-Fi range extender.

Device Limitations:

Older devices may not support higher-speed connections. Ensure your devices are capable of handling the internet speed you are subscribed to.

Router Placement:

Place your router in a central location to ensure even coverage throughout your home.

Background Applications:

Check for background applications or devices using bandwidth. Streaming, downloads, or automatic updates can affect speed.

Malware or Viruses:

Run a malware scan on your devices to ensure they are not infected, as malware can consume bandwidth.

Network Interference:

Other electronic devices or neighboring Wi-Fi networks can interfere with your signal. Change the Wi-Fi channel to reduce interference.

Faulty Hardware:

Check for faulty cables, connectors, or a malfunctioning modem/router. Replace or repair as needed.

Can't connect or internet dropouts?

Check the Basics:
Ensure that all cables, including power and network cables, are securely connected.
Restart your modem/router and the device you are using to connect to the internet.


Device Issues:
Confirm that the device you are using has Wi-Fi turned on (if applicable) and is connected to the correct network.
Test the internet connection on multiple devices to see if the issue is device-specific.


Network Outage:
Check if there is a network outage in your area. You can do this by visiting nbn's website 
NBN Outage Checker .

Wi-Fi Signal:
If using Wi-Fi, check the signal strength. Walls and other obstacles can interfere with Wi-Fi signals.


Wi-Fi Interference:
Change the Wi-Fi channel on your router to reduce interference.
Check for interference from other electronic devices, neighboring Wi-Fi networks, or appliances that may disrupt your Wi-Fi signal.


Signal Range:
Ensure that you are within the effective range of your Wi-Fi router. Walls and obstacles can reduce the signal strength.

Router Issues:
Restart your router to refresh the connection.
Check for firmware updates for your router and install them if available.


Overloaded Network:
Too many devices connected to the network can cause congestion. Disconnect unused devices or consider upgrading your internet plan for higher bandwidth.


Faulty Cables or Equipment:
Inspect cables for damage and replace any that appear faulty.
Test with an alternative modem or router to rule out hardware issues.


Software or Firmware Issues:
Ensure that your device's operating system and drivers are up to date.
Check for and install updates for any network-related software.


Heavy Network Traffic:
Internet dropouts may occur during peak usage times. Check if the issue persists at different times of the day.
