HAP Ac3 as dumb switch + access point

RouterOS Wireless Networking
1

Desired outcome - Allow any Eth port on my HAPAC3 to be plugged into an existing network and have the existing DHCP range be passed-through to whatever else I plug into the other Eth ports / connect to the Wifi of the HAPAC3.

On more basic routers like Asus / Tp-link etc, this is accomplished by disabling the routers DHCP server, and then plugging it into the existing network.

I've attempted to set this up myself, but I must be missing some config / understanding.

Your try seems mostly fine. You can try to manually add interfaces one by one to bridge instead of using interface=all, this construct is not used often and could feature some hidden bug.

Thank you @mkx.

Removing all i-faces and adding Eth1-5 + WLAN1-2 gave me the result I want. Seem’s like adding the bridge, breaks the config. I think this is a lack of understanding on my side, and not a bug.

From default…
Remove firewall filter and nat
Remove DHCP server
Remove IP address from bridge.
Move DHCP client to bridge.
Add ether-1 to bridge.

Then you should have a 5 port dual band WAP to configure.

Using the Wifi WAVE2 driver gave me a much better client serving radio… But it broke a few things in my ACLs.

So basic WAP… Use the WAVE2 drivers. The ACv2 works far better than the older standard.
