Hi, I'm having stability issues with AX55 v1 where my internet drops periodically for 5-10 secs, usually hours apart. I have noticed the LAN light turning off for a few seconds when it happens. I've been pinging google.com while playing games (war thunder) and I get ping timeout when it happens, as well as package loss in the game. This has been occurring for at least a month. On rare occasions I get several internet drops consecutively e.g. internet drops -> back up for a few secs -> internet drops again -> back up ect.

I do not have this issue if I use my ISP's router (EX3300). I have only testet this over ethernet - not on WiFi.

I have set up AX55 with VLAN-tagging as required by my Danish ISP (https://www.hiper.dk/hjaelp/udstyr/vlan-tagging). I have two SSID: one for WiFi on 2.4 GHz and 5 GHz, and one for IoT.

What I have tried:
 - Resetting the router
 - Changing DNS to 8.8.8.8 and 8.8.4.4 instead of default 8.8.8.8 and 1.1.1.1.
 - Using static IP (Internet Connection Type), does not work though - it will not connect to the internet at all.
 

Setup:
    fiber cable -> Fiber router -> Router (AX55 or EX3300) -> PC (ethernet cable)

Below are the logs of two examples when it happens when pinging and router(AX55) logs.
