I’ve an AT&T BGW320.
Static IP Address
The router has a DHCP range assigned (see screenshot below).
On your Plex Media Server, manually configure it for an IP address outside of the DHCP range.
For example, if the DHCP range on the router is 192.168.1.64 to 253, assign an IP address lower than .64 to the Plex server.
Login to your router to verify DHCP range before configuring a manual IP address on the Plex server. You will need the router password to see the DHCP page. The default password should be on the back of the router.
Also, ping the ip address before configuring the server just to make sure it is not in use. You can ping it from any system on the network. Timeouts or Host Unreachable messages means nothing is using the address and it is OK to use it for the server.
