ePMP, MicroTik CCR 1036 Hotspot & D-LINK routers

I have a CCR 1036 and configured to use hotspot for DHCP server and Captive Portal . I also have a Cambium ePMP network. I realised that some end-user router brands like D-Link and Wave-Link are not able to reconnect to the MicroTiK timely and do not work as expected. Whiles Tenda and Netgear are owesome with keeping customers Online. Am l missing something? I want to be able to use my D-Link & Wave-Link router over the hotspot. Any help?
