I had a router crash during a firmware update and I got everything back up except my Like Duo. Here’s the catch…it had a static IP from my router before the crash. So I am thinking it is a problem there. I’ve rebooted the Live Duo, router, PC. Nothing will detect it. I’ve directed connected the LAN …

Best bet is probably to ensure that DHCP is working on your router, and then do the RESET that’s documented in the Manual for the Duo to reset the network settings back to default.
