pppoe - ptp - problem

Good day

I have an old problem and I need your opinion so that I can solve it.

I have Mikrotik pppoe server giving to a 5GHz point to point link (2 Mikrotik routers ) , the last router have a PCMCIA 2.4GHz WLAN that distribute to Clients.

The PTP-Link are both configured as bridge with WDS, all interfaces in each router are ports of a single bridge ( Bridge = Ether1,2 Wlan1,2).

The clients can connect as pppoe to the server normally when using an Access point.

But Wlan clients cannot connect, but they can if I give them a static IP.

I want to solve this problem, what kind of configuration should I use for the 2 routers.

Please help

Best regards
