Nighthawk xr1000 intermittently drops internet connection

[Dank90]

I have an Nighthawk XR1000 on version 1.0.0.64_1.0.49 connected to a Nighthawk CM1200 modem, the router will just randomly go from connected to disconnected status for internet and my PC connected via ethernet will lag/buffer until it reconnects. I can still access the router dashboard with no issue and the status goes back to connected after a few minutes/seconds.  While disconnected I do not see the IP lease changing and at Monitoring > Show statistics I see TxPkts/RxPkts increasing so it looks like it is receiving packets from the modem.  Spectrum says they don't see any issues with the line after some coax cable from the DMARC to modem was replaced and that helped with some of the issues we were having, now we just need to fix these random disconnects any help/ideas would be greatly appreciated.

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

Nighthawk Pro Gaming Routers - NETGEAR Communities

Gaming routers have their own DumaOS operating system that is nothing like the one on Netgear's standard routers.

You might like to search there for messages related to your problem.

I will ask the Netgear moderator to move your message.

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

Check for various troubleshooting tips.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

yup I went through some articles for my model https://www.netgear.com/support/product/xr1000.aspx#download and it looks like I am on latest firmware version but the firmware version may also be the issue so would need a recommended stable version to roll back to if that is the case.

Not something you will find here.

Try in the appropriate section.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200 on the XR router.

Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute then back ON.
