Second wireless interface not handing DHCP addy

RouterOS Wireless Networking
1

I have 2 wireless NIC's installed in my routerboard. The wlan1 NIC is operating properly allowing clients to connect
and they receive a valid IP address from the DHCP server. The other wireless interface, wlang, allows connections
but does not hand out an IP address. My config looks right though. Any suggesstions??
Flags: X - disabled, I - invalid

Any help would be much appreciated.

It looks as though it is receiving transmissions but not sending transmissions. Interesting, eh?

I can’t seem to figure this one out. Why would I only get one way traffic? The interface refuses to transmit out…

Looks like you have three dhcp servers on three interfaces using the same ip pool. Can you post “/ip address”?

No duplicate subnets here. Change the ip/subnet on ether3 to 172.16.32.1/27 (or something like that). Then set up a dhcp server on it using that subnet.

Or remove the ip assignments on ether2 and ether3, then put both interfaces in a bridge. Assign 172.16.31.1/27, and the dhcp server, to the bridge.
