Hey network guys: before I bug my telco about the modem, could the
ethernet switch be failing to broadcast the arp request to the modem for
some reason? (I guess I could run a wire direct and check)
[silver]$ ping orange.local

rtt min/avg/max/mdev = 1.006/1.181/1.357/0.175 ms
So, once the wired computer's arp cache is warmed up, the problem goes
away. There is no issue doing the reverse experiment on the WIFI laptop
"orange", even after clearing silver's entry from its arp cache.
Thanks.
