Given how different the results were, there has to be more than "not running the exact same command". I mean, their connections, maybe some hardware, cabling?
Nope.
I'm sorry, but I give up. I can't keep up with you. I have no idea how you hope to diagnose anything when you change variables and topic all the time.
Just see the output of my commands that prove the problem is inside the router. It refuses to talk with my SW2. It is crystal clear.
Summary:
1 2 router-----sw1------sw2-----telcontar \ \-----isengard \Legolas
ping telcontar → isengard : 0% loss ping isengard → telcontar : 0% loss
ping telcontar → router : 0..30% loss
ping isengard → router : 0..30% loss
"router" is hopelessly ambiguous here. "Router" by definition has multiple addresses and you neither showed your complete addressing plan nor told what router address you access.
ping isengard → legolas : 0% loss
ping isengard → sw1 : 0% loss
This lacks legolas - router tests.
1 2 router-----sw1------sw2-----telcontar \ \-----isengard \Legolas
ping isengard → legolas : 0% loss
(uses the switch part of the router)
ping isengard → legolas : 0% loss wifi of router
So far from this summary, pings inside your LAN are OK and pings to an unknown address that you call "router" are not OK. I fail to see how it points at one of the switches as the root cause. And it certainly lacks tests from the switches themselves.
I repeat:
I had one router for years, no trouble. Comes the technician, changes the router.
Connectivity from computer room to router and internet is fully lost.
How are we expected to know what a "computer room" is and what devices are there?
