In theory it “could” work. The problem is the setup/power up sequence I think. I am not a livewire expert.
If you have auto WAN configuration, meaning your existing linksys router does not have any special passwords/logon information for your ISP inside, it should work.
This guy did it…
and here…
-
Unplug all power
-
Plug livewire into modem Ethernet
-
Plug other livewire into router upstairs
-
Power up router, then livewires, then sync livewires
-
Power up modem last
The problem is the modem IP address or livewire Ip address. I think you need to power everything up in a sequence in order to make it work for the first time.
Understand that the livewire network is pure WAN, no NAT firewall, no security, etc… At this point. If you manage to make it work, be careful plugging anything else into live wires. If your modem only has a single IP address, or no DHCP, you will be limited to a single device on the livewire network. Example - Coax>Modem>Livewire>Router>all other devices.
Your router needs to handle all of the other devices.
