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.

Comes the technician, changes the router. Connectivity from computer room to router and internet is fully lost. Comes another technician, days later. He looks around for an hour or two. He is baffled. Finally, I manage to convince him to TRY another router. Goes to the car, brings another router, connects it ad hoc, temporary like, not believing me, and hey presto, connectivity is back. Caveat: 30% loses with computer room. He does the replacement. He does look around for half an hour or more, doesn't find the problem. Ok, fine, I say, this is better, don't touch it. He leaves. If the router change caused the problem, the culprit is the router, period. I don't have to test anything else, but I did. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
