It is possible that this host does not respond to ping, you would have to
try perhaps tcp on some port. Try this one:

nping -c 10 --tcp -p 80 SomeMachine.

you may have to install nping.

-c is the number of pings, one per second roughly.

nping -c 900 --tcp -p 80,433

I try it:

Telcontar:~ # nping -c 10 --tcp -p 80,433

I forgot to mention that you can try probing with different ports till
one responds. It is possible that the machine (if it is
still that address, I told you to verify this before pinging it) doesn't
respond on the ports I wrote.

Anyway, even your own gateway has problems, 80% failure. That's pretty bad.

I don't know why with a computer with Tumbleweed on this network, I
have an issue, and with a same computer, with Leap 15 or Ubuntu 16.04
on Live USB, I haven't an issue on the same network, and with a same
computer with tumbleweed on another network, I haven't an issue.

Cheers / Saludos,
