Wi-fi and Security Certificate

Security Certificate

Our Internet Service Provider is N4L. 

In order to use the internet on JHC-BYOD wifi you are required to install an access certificate onto your BYOD device. If you do not install the certificate, your access will be very limited. 


New security certificate (from 1 June 2019) not required on Chromebooks


N4L are upgrading their service requiring all network users to install a new security certificate. The upgrade will happen on 31 May. Students should install the new security certificate during May so they are ready for the changeover.

Please follow the instructions specific to your device(s) to download and install the certificate.

  • Chromebooks have the security certificate automatically installed when they connect to the JHC-BYOD wifi.
  • Please install this certificate on any personal device you use on the JHC-BYOD wifi such as your phone, tablet, laptop etc.
  • You do not need to install this on school owned devices as these will have the certificate installed automatically.

N4L - our school internet provider

N4L (Network for Learning) is a government managed network, providing digital content (the Internet) to help teachers and students navigate the complexities of learning in the 21st century. This provides fast and free internet access to the school.


The school is subject to N4L filtering and other protocols.


What does this mean for users at JHC?

It means that student’s internet will be subject to filtering (as it has always been) and access will be logged to make sure it complies with the school policies and standards. 



Reporting on internet use will be done but individual users internet use will not be monitored unless there is a good reason.

These are the types of reports that the onsite engineer can create. They are used for for trouble shooting technical issues, for monitoring heavy usage or harmful use in relation to the safe and efficient functioning of the network.

Here is an example of an individual report that could be created. You can see how much data has been used. You can see the names of the websites that have been visited.

Web filtering information gathered will be a useful tool to support our digital citizenship policy.



Here is a link to N4L's privacy policy


Secure Filtering

Some sites use secure connections and the school will have the ability to monitor these connections but some traffic will be excluded such as Internet Banking for privacy reasons. 



To enable Secure filtering a certificate is required to be installed on BYOD devices. This enables the school to maintain digital policy and standards. Please note, these certificates will only apply while the device is on the school wifi, and will not impact any device use at home or elsewhere. ​You can download the certificate using the link at the top of the page.


Blocked Sites

If a student decides they need access to material that is blocked by filtering they need to discuss this with their classroom teacher in the first instance. Teachers will be able to have the blocking policy reviewed by the Network Managers if they deem it justified. 


Help to Install the Certificate

At Senior see the Student Tech Support in the library before school, interval and lunchtime.

At Junior come to the library at 1.10 on Tuesday or Thursday with your device.
