blinking amber ethernet light

Question

This is my second modem from netgear and this is the second dead modem. Both modems have the same problem occuring, the moment i buy them they are fine then around 2 months later they start doing this. Now, i know its not my cables because they work fine with 3 different routers and it cant be xfinity becuase they have came here 4 times already and have said the issue is on my side. I've had another modem from arris and that works fine with both of the coax and ethernet cables. I have xfinity blast meaning 500 mbs+ download 20 up. Yes i know my modem is stuck on 100mbs channel im trying to see if theres a fix for it software if not hardware.

Be sure your using good quality LAN cables, CAT6 is recommended.&nbsp;

I have a google onhub and a&nbsp;R6400v2. Both on new cat6. I've switched between both routers many times and they have the same problems. Even a direct connection to my pc form the modem causes the same issue.

Looking at the user manual on the CM modem to check LED behaviors:&nbsp;https://www.downloads.netgear.com/files/GDC/CM700/CM700_UM_EN.pdf
&nbsp;
Ethernet
• Green. A powered-on device is connected to the Ethernet port at 1000 Mbps.• Amber. A powered-on device is connected to the Ethernet port at 10/100 Mbps. &lt;&lt;&lt;&lt;&lt;• Blinking green or amber. The Ethernet port is processing traffic. &lt;&lt;&lt;&lt;&lt;• Off. No device is connected to the Ethernet port.

Yes i know all of this already, i've done some research already. I was just having one last glimpse of hope for this modem to actually start being useful again. But i guess not, thank you anyways.
