I have a configured and working fine router RB951G-2HnD with the additional access point (AP) connected. Now I need to configure internal AP in router with different SSID. So I need to have a second standalone AP.

I had successfully configured wlan1 interface. I can see the authenticated clients but all of them does not receive IPs via DHCP server. If I understood correct I need to setup a bridge interface and add two ports eth2 (LAN master port) and wlan1 into it. When I adding eth2 port into bridge on the DHCP server window I see that string becoming red. Is it DHCP conflict due to another AP is in use? Could somebody give advice please how to configure it correctly?

This is because you will need to run your DHCP server on the bridge interface and not directly on the ethernet interface.

Yes I thought so and it is true. Now it works fine. Thanks!

Please help to configure
I have 2 ADSL lines of 5 mb each wired to RB 750 routerboard on which I run hotspot for the users in the building through ethernet cable networked
My question is -- i want to install wireless devices RB951G-2HnD in each floor of the building connected through ethernet cables and use these devices as access points for the users in the building and later stop using ethernet network
I still want to use RB750 as hotspot and give IP addresses to the users.
I tried to setup RB951G-2HnD with quick setup with winbox, I get the IP from RB750,,,but I cannot access when i am connected through access points....and also all the ethernet network users also cannot get to the Internet...I will get IP for all the devices,,, from RB750 ...but no internet when I plug in the RB951G-2HnD as AP in the network
please help me?
