BLUF: While this modem "should" work with all ISPs, if you have Optimum save yourself the headache and just get something else. Optimum couldn't explain why it didn't work and I ended up going with an ARRIS SB8200.
This device is quality and works right out of the box (unless you have Optimum ISP) and for the most part, I have never had issues with Netgear products and was looking forward to using this device.
However, a word of caution using it with Optimum ISP. I got the modem, unboxed it, followed the instructions to plug in the coaxial cable, and powered the device on. The lights worked fine, everything turned green. Got on live chat with Optimum, and they saw the device, I gave them the MAC, and they authorized the device on my internet line. They said to give it 20 to 30 mins and reboot it then should be good to go.
Well, it wasn't. While this modem showed an internet connection, my router said otherwise. Naturally, I thought my router was the issue so I hooked up a second one I had. The same issue, the modem had internet connectivity but not the router. Back on live chat with Optimum, they said they would re-check the MAC, that was good. Then they said they would send some signals to the device. That was good. Then they said to reboot everything and still nothing. Frustrated, I decided to run to the local Walmart and grab a similar modem with DOCSIS 3.1 but ARRIS brand.
I got the device home, swapped the new one in, and back to live chat with Optimum. They added the device MAC and authorized it and after a few mins of waiting and rebooting the router and modem I had internet again. After this most of the day struggle, I looked into some other reviews online and it seems that this CM1200 has given many users with Optimum ISP this or similar issues.
I'm not giving this product a bad review, hence the 4 stars but this is a caution when using it with Optimum ISP. It may work or it may not.
