CM1200 disconnects

I had the EXACT same issue with my CM1200. I bought mine new along with a new RAX120 since I was going to have my kids going to school remotely and my wife and I would be doing work from home. 

I started to have issues about a month in and had my ISP change all the lines to my home since I thought it was their issue and not my new hardware. After the replacement, I was still having issues and contaced Netgear to get support with my router (What i thought the issue was since I was getting dropped signal). It was past the 3 months of phone support but they decided to help my anyway. AFter the help, everything worked fine for about 2 hours then everything went down the drain. I wasn't getting any connection AT ALL! I called Netgear support back to help with the issue that they just helped me create and they told me I had to pay for the support!!! I was a bit frustrated with them since you were able to "help" me 3 days ago and ruin everything. Well, they told me I was not going to get any support unless I paid them.

Next step for me, I just replaced my router (bought another brand new one but not from Netgear, since I had a poor experience with both the item and ESPECIALLY the support). This was working fine until I started to have the same issues again. I called my ISP and they redid everything in my home again. Upon testing the modem, they were getting faulty signal/weak signal output from the modem. The tests they were running wouldn't even complete without the modem rebooting itself. So, I had them install an ISP provided modem. 

I called Netgear support, with very low expecations, and got the same run around. I had to pay for phone support in order to get the help. They mentioned to me that it is not a hardware issue since the device "powers on." All they were able to do was try to sell me the phone support and send me an email with trouble shooting tips (power cycle my modem).

All in all, I've been a big fan of Netgear for the past few years but this year has been a complete changer for me and they just lost a loyal customer!!!
