Because my HP older printer is entering in sleep mode, I created 2 cron jobs:
*/1 * * * * wget -q -O - >/dev/null 2>&1 #hpweb#
*/1 * * * * ping -c 1 #hpping#
But now it seems that in the mornings, I still have ping but only from the ssh. The printer is on 2.4Ghz, all other clients are on 5Ghz. And the ping from 5Ghz is not working, even the ping from ssh is up.

So now I am trying to ping by mentioning the 5Ghz interface like this:
[email protected]:/tmp/home/root# ping -I eth2
PING ( 56 data bytes
--- ping statistics ---
35 packets transmitted, 0 packets received, 100% packet loss
But I have no response. I tried also with eth1.
Could you please share some ideas?

Thank you so much,

Might try using the bridge interface instead

ping -c10 -w10 -I br0
and maybe substitute ping for arping
