Bridging wireless routers

"Here's your router manual page. Universal repeater mode (also known as WDS) should work. But if it doesn't, it might be a vendor conflict.

Make sure the position of the repeater must be able to receive a strong signal from the access point sources, the stronger the signal received, the better it re-transmit.
Configure the access point with the repeater sources to have the same SSID and Channel.
It should be better if you equate the type of subnet IP address of the access point with repeater sources, also it would be better you use a static IP address.
For the WDS feature, enter the MAC address of each access point with the repeater sources.
Update the firmware of each wireless radio in order to avoid the bugs that arise later."
