Intermittent service

For the past 2 weeks I have had intermittent connection. The fancy Panoramic modem/router will lose connection anywhere between every 5-30 minutes. I got a replacement panoramic device and new cables. I have reset it on my end and through customer support. This does not seem like an isolated issue as a simple google search shows many other have had this problem for the last 5 years. Another issue is I do not wish to pay for a tech to come out here an tell me my hardware is good and can’t diagnose at their level and then pay for another tier technician. I would like a refund for the time it has been intermittent and until it is resolved then I would be comfortable paying for your physical support. 

In the time it took me to post this, it has gone out twice.

Edit: Since posting it has gone down twice again.
