Netgear CG3000DCR

I am having the same problem as this post, may be the couse of my paket loss and why when I reset my peronal router it works for awhile. I have the same router firmware and hardware as lited below. I also posted on not connecting to new router on the WAN

"Hello! We have Business internet 50 down and have the original CG3000DCR that we got several years ago. Is that gateway still relevant? Is there a way to get it updated? I ask because we have been having issues where the latency goes crazy, pings to 8.8.8.8 will go up to 500, 1000, 2500 ms and drop a few packets. When I reboot the modem it works for a while before going back to that.

Thanks!

Firmware is 3.01.08, hardware version 1.04"
