N900 CG4500BD connection constantly dropping, cant find support for my router/modem anywhere.

Hello i bought my Router from my ISP and cant seem to locate support for this router anywhere on their or netgears website. I'm constantly losing internet connection and the router itself resets about 5-10 times daily. i have had my ISP come out 2 times and both times they left thinking it was fixed, seems to work for a while but then it starts happening again. I have tried many things, nothing has worked. I was going to try and update or change the firmware to see if that would fix it since other people have had luck with that but i cannot seem to find my router on netgears list of products nor can i find firmware anywhere else on the internet, not even from my ISP. At this point i need help from anyone that has any idea where i can find information on my product, or any ideas how i can fix my internet.
