Have a GL.inet GL-MV1000 (non-WIFI) and testing some WAN failover scenarios.
Have fiber/PPPoE primary ethernet uplink with Netgear Nighthawk M1 in USB tether mode for backup. Seems if I disconnect the primary ethernet link, it doesn’t failover to the tethered uplink.
From my research, the tether link should be a secondary by never seems to kick in upon primary failure.
EDIT: I should add, I have installed mwan3 modules suggested in other posts, but default config doesn’t seem help.
Am I doing something wrong?
Appreciate any help.
