Netgear Nighthawk R6700 periodic network disconnects

[Null_Sum]

Hey all! I have a problem that I cant seem to fix, my router seems to be disconnecting every 40 -60 seconds and stays disconnected for around 10 -15 seconds, both wireless and hardline are doing the same thing, I'm currently running firmware version V1.0.1.16_10.0.30  (this has been going on for several versions now). I'm hoping all of you can help me find an answer to why it is doing this. I have looked at the router logs and there seems to be no reason why it is doing this.

Hi Null_Sum,

Please try changing the MTU size of the router.

Hi Null_Sum,

1. When you say disconnected, is it disconnected from the network or still connected but no internet access?

2. Check your mode as well. Connect a computer directly to the modem and make sure the connection is stable. If not, contact ISP.

3. If connection is stable from the modem, reset the router to factory default.

To clarify I lose internet access, it will look normal until I try to surf then my computer's will register something is wrong and I hardlined one computer and although it doesnt happen as often it still happens I will try to restore to factory defaults but I'm not sure why that would be the problem since it's been working fine up to a couple months ago.

Hi Null_Sum,

Bypass the router. Connect a computer directly to the modem and make sure the connection is stable. If not, contact ISP.

OK so I reset router to factory defaults and still the same issue, I have also bypassed the router and the issue no longer happens
