Can't connect to Profilux 4 after 5.02 FW upgrade

[donaldchaney]

Hello,
Since the upgrade to 5.02 FW, my Profilux 4 no longer shows in my router DHCP client table. I did not make any change in the routers settings.

The Profilux 4 is connected to the router using a network cable and i can access the profilux 4 from my laptop wirelessly no problem, but as it has no IP i cant get the webserver up.
undertale yellow
under LAN setting in the "System" tab on profilux control its set to obtain IP address automatically which is fine and i have put my external IP address in the external IP address field but that didnt change anything
