What I heard from others is that speed settings for WAN/LAN Ethernet ports are useless, since they do not work. _________________ 2 times APU2 Opnsense 21.1 with Sensei

if you can;t do it in dd-wrt, you could put a managed switch between the router and the modem and set that port on the switch to full duplex. _________________ Please state what make and model router plus the build number and type of DD-WRT you are using.

Can I force my wan port into full duplex mode ? My internet provider requires this for my connection to work properly.
Thanks,
David
Full duplex is not a force-able setting, it is a negotiation between between the 2 nodes and if your ethernet cable is ok then you will get full duplex. _________________ Kernel panic: Aiee, killing interrupt handler!
