I have a modem with an included WIFI router and LAN ports. To that modem, I attached an ASUS WIFI router and a NAS. To the ASUS router, I attached a sound receiver.
I had some issues because of both the modem and the router running a DHCP server. Therefore I turned off the DHCP at the ASUS router because the modem is serving IP addresses. But now the sound receiver does suddenly disappear from the network.
My question now is what is the best configuration?
Should I run the DHCP on the modem or on the router? Or on both with a defined, not overlapping, IP range?
Also: I found out that when the ASUS is connected to the modem via the WAN port I experience massive amounts of package loss. That is not the case when I connect both via the LAN port.
