Model: Archer A7  
Hardware Version: V5
Firmware Version: 1.1.0 Build 20201120 rel.50399(5553)

My Archer A7 keeps disconnecting almost every day or so, when it happens, the orange light is on for a couple of minutes and the internet will be back to normal.  Below is the system log for your reference(the disconnection happened at 12:17):

@GGWP 

 

For your security, please edit out your public IP which starts with 75.x.x.x.

 

If you happen to have a cable modem, I would log into that and see what the system logs show on that. Mainly looking to see if you have any critical 3 or critical 4 errors. If you do, that may explain why you are getting random internet drops. The modem is saying the internet signal that is going to it is not stable. I would reach out to the ISP and specifically mention the random drops and the errors you are seeing.

 

In the meantime, your router internet light turning amber is indicating an internet connection has stopped. The router still "sees" a connection as it is amber, but no connection to the outside world. Try swapping the Ethernet cable with another if you happen to have another one.

@pearsontrey 

 

Have you checked the modem log as suggested by Tony? BTW, who is your ISP?

 

Ensure the modem internet connection is stable by connecting a computer to the modem directly and monitor for hours.
