Hi all,
I have a pi3 with normal and wifi eth interfaces under the same stack.
Wifi address is 10.12.12.15/16, the address of the other nic is
10.11.12.15/16,
/net seems to be correct, the connection to the AP is up and running.
But:
(1) ping wifi 10.12.12.15 doesn't work when the Rj45 is unplugged
(2) ping wifi 10.12.12.15 works when the Rj45 is plugged
(3) the arp tables on the net all have a correct 10.12.12.15 entry
(4) ip/ping -a to 10.11.x.x or 10.12.x.x always displays
10.11.12.15 -> ... and doesn't work when the cable is unplugged.
(5) with/without cable, "snoopy /net/ether1" (wifi nic) shows
icmp packets when pinging.
I'm quite confused.
Could anyone kindly tell me where is my mistake ?
Thank you so much
adriano

When this situation occurs on *any* OS I'd check the "defaut" route
and/or the connectivity of the other end. You don't say what the
connectivity of the other end is for the tests you've performed
and it makes a difference to the ability of the pi3 to respond via
the correct interface.
