Nighthawk R8000 goes offline
My router is consitently losing or dropping its internet connection. I am running firmware v1.0.4.76_10.1.82. My ISP, Frontier Communicatoins, provide me with a modem/router. I have that modem con...
My Netgear router is connected to an Arris NVG468MQ router.
I don't know how to find the answers to your questions
Is the gateway in passthrough/modem only mode?
Or the netgear in access point mode?
That gateway is a modem/router/moca adapter combo device.
it causes a double nat which can create some network instability.
A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

Probably the easiest option to to put the netgear in AP mode. But there are drawbacks as outlined above.
plemons,
Thanks for the insight. I went with option 2. It does not appear that the Arris modem router can be put in a modem only mode and I did not like the loss of routing options caused by option 3. I have also turned off the 2.4 and 5.0 channels on the Arris router.
I haven't noticed any loss of function with any of my devices that are connected via wifi or hard wired. I will report back in a week as to whether this solved the problem with wifi dropping.
It looks like in a perfect world I would replace the Arris modem router with a Frontier compatable cable modem. That would save me $10 a month and eliminate any potential double NAT issues.
good luck! Keep us updated
Sadly this did not solve my problem. Intermittently, I continued to get the same issue where many devices in the house did not have internet access. Oddly, smart phones and tablets seemed to be the issue most frequently. Rokus and Kasa devices and echo dots still worked for the most part.
I was ready to throw in the towel and replace my Frontier provided router with a pure cable modem so that I didn't have the risk of competing wifi signals or whatever the problem was. In doing research on replacing the Frontier equipment I learned that my Netgear Nighthawk is supposed to be Frontier FIOS compatable. So yesterday I unplugged my Frontier modem/router and moved my Nighthawk into the media closet. 24 hours later everything is still working fine.
By moving the Nighthawk from the middle of the house on the second floor to the front of the house on the second floor we had buffering issues on the first floor in the back of the house. This is whey I put my Nighthawk in the middle of the second floor in the first place. I fixed this with my Netgear N300 range extender. If this solution proves reliable I will probably upgrade my range extender. If this solution proves reliable I will send the modem/router back to frontier and save $10 a month.
