Yesterday I got my first own MikroTik device - comparing it to previously used tplink, etc - it's the most powerful I've even known
Let me go to the point.
My topology looks like (it's only a draft, needed for explanation issue I'm facing with): The problem is with the devices directly connected to the Asus RT-AX55 over the LAN, especially my laptop. All devices connected via WiFi with AP are working as expected.
Except the laptop, I have the RPi connected on LAN port also (it has an access to the Internet, but can't ping my laptop on LAN IP address or WiFi either).
Yesterday, I spent a lot of hours looking for similar situation to mine, but no luck. Of course, found some of them, but the topology was different.
What I also noticed - when I'm changing a port in the Asus AP to another one it starts working, but for a while only - after 5 seconds or less, it stops.
Yesterday, by end of the day I swapped places the cables between RPI and my laptop and it worked much longer than above. Happy, I went to sleep and today is the same.
I don't have any ideas how to fix it, but I hope you have.
Here's my configuration:
