Intermittent connection

I have logged numerous calls, emails and Facebook messages with Afrihost and is receiving no feedback from them. Hoping you can assist as we are connected through Clear Access via Afrihost. I have an intermittent network connection. Every time my router or ONT box is restarted my WAN IP defaults to a 192 IP along with the gateway. I have been nagging for assistance for a day now with no assistance or feedback from your side. What can I do to get someone competent to assist me as the usual “please reset the router” standard Afrihost troubleshooting routine is just not cutting it this time around.

Thanks
