Using one ether port on 750G for Wireless

I’ve got a 750G and was wondering how I would set it up to use ether3 as a separate wireless network?

ether 1 = WAN
ether 2 = LAN
ether 3 = WLAN (connected to a WAP54G)

when first started the router it automatically set up ether3 as a switched (RS) port to ether2 the lan (Master). I want to be able to set up ether3 with it’s own DHCP address space and it’s own firewall rules. More importantly I want it to link to the internet (WAN) separately.

I’ve tried taking the master/slave feature off but that doesn’t seem to work.

Any suggestions?

Remove master port from ether 3, now it is independent port and you can set up dhcp on it.

ok I’ve removed Master from ether3 and created a new dhcp server to assign ip to wireless computers but nothing is working. The wireless AP is not getting an address.

where did I go wrong?

Hard to say without your configuration.

Post “/ip address print”, “/ip route print” “/interface ethernet print” and “/ip dhcp-server export” for starters.
