True. But it's better than manually switching things around. hrmm... I just went back to the original post; I missed this bit the first time around: > In this setup i'm using a D-Link 8 port switch to connect eth0 using > ethernet cable and eth1 is connected on wireless adapter of my laptop. eth0 and eth1 are probably on two different networks (same as my wls1 & enp1s0 are on two different networks); that'd be my guess for why failover doesn't work. Both NICs need to be on the same network for bonding to work. Lee
