GT-AC 5300 LAN dropping out (in traffic stats)

Hi All,
Please excuse any mistakes or lack of forum protocol with my first post here.

WIred LAN dropout

I have recently purchased an AC5300 (firmware 3.0.0.4.384_81695-gfade4d7) I am keeping an eye on usage of my devices and have noticed that periodically my Wored LAN throughput spikes down to zero. I don't know if this is genuine or a bug. I'm wondering if there may be something on my network that is sending out corrupt packets, or if it is something malicious or anything else or perhaps even a router issue.

I just wondered if anyone might have any clues where to start please, other than individually turning off each and every wired device to figure out which is causing it. That might sound easy, only 8 LAN ports, but I have tp-link powerline devices in the house also and the main one plugged into a router LAN port.

There is nothing in the router system log that coincides with these spikes (that I can see).

Any clues or ideas welcome please. ?



Second observation/issue

A slightly related note, using bandwidth monitor also shows WAN download speed of circa 4MB/S (first image) but in this picture attached I have a PS4 doing a download and it's showing 32.x MB/S in the individual clients and over view screen (my maximum) in the client list, why doesn't the WAN show 32/33 MB download in the traffic statistics ?

Thanks for any possible assistance / ideas. Images attached below.

if possible, setup a ping session on your lan device, and see if the drop take place, and the ping session stop correspondingly.

Thanks, I will try this.

I have attached the recent log. I have notices a few entries as follows: (this is filtered) what port is eth2 (Ext Swith port 1) (logical port 9) is that the ethernet 1 cable ? I notice it seems to go down for about 5 seconds at a time ?

attached Further down is the full log, can anyone spot anything of concern in there ? For some reason the box rebooted itself (I assume today , when the date reset to May 5th again).

Full log here if anyone can spot if router is doing something strange https://drive.google.com/file/d/17rQKxKmTtF4-QywVbEz7JcjgNIS7n9n_/view?usp=sharing

I noticed the following in the logs,

Ethernet Auto Power Down and Sleep: Enabled
May 5 06:05:15 kernel: Energy Efficient Ethernet: Enabled

How do I disable this to see if this is causing the drop ?

not sure if your client card always attaches to LAN 3
just make

1. disable client card eco mode or power saving mode
2. swap to other LAN port

the eco function can be turned off using the phone's router application, there is the "ASUS ROUTER" function
