You haven't explored the Ubuntu network guide page yet? What directories exist in /etc/network/interfaces and what information do they hold? Can you share the details from the dhcpd.conf file? Also, remember that the output of 'ifconfig' could be useful—remove any public IP addresses if you're cautious. Do you recall how you previously set up your server's network? Were you using a graphical interface like Gnome, or another method? Keep in mind that both your modem and router may use separate DHCP servers. Which subnets do they belong to? Are your devices connected to the WAN or LAN ports, and are they on different subnets? What subnet settings apply to each? If they share the same subnet, it could lead to multiple DHCP conflicts.
