Thanks for the additional details, @Jono87.
We'd like to arrange a call from one of our Technicians for further test and investigation. Let us know your best contact number and preferred time.
Thanks for sending us your details. We will pass this to our Technical Support Team and request for a call tomorrow night between 7:30-8:30PM AEST.
Make sure to keep your mobile phone available and let us know how it will go.
My apologies for the missed contact. We both want your issue to be resolved. I can organize another call from a Sr Technician. Can you provide us your preferred callback time?
That being said, I reviewed your response to the questions I previously raised. It seems like this could be a WIFI interference issue. Were you able to change the WIFI channels for both 2.4GHz and 5GHz networks? Visit this link on how to make the changes.
