If you have a cable modem, look at the system logs on the modem, not the router. If you have critical 3 or 4 errors, that may be the cause which means the internet signal is unstable. 

If that is the case you will see random internet drops with other routers as well if you happen to have to swap the A7 with.

Otherwise, it may be the A7 with a bad WAN port.

Thanks for the reply! I know for sure it is not the isp or modem. I have had no issues with a spare router. I do believe this is software based as the issue happened after updating. I do not believe it is a bad wan port unless that can cause it to be perfectly fine for hours and then randly reset. I believe it's related to when it tries to renew it's ip with the modem but the logs don't support that idea though.

@khmartinsen I have the same issue with an Archer AX1500, but it happens every 24 hours.

I suspect it is also due to some DHCP lease, but I'm no expert and support wasn't able to offer any help beside "change the wifi frequency"
