Thanks Tony and sorry for the wonrg placement. Quick followup, i have only one DECO M4 (router mode) , that is the satellite ? If that breaks and i replace with another one and make it main it will...

Second time i open the thread, the other vanished. Is there any way to backup the M4, i mean you drop it it breaks and you buy a new one. Can i restore all settings, reservations port forwarding etc....
