Hello can anyone point me in the right direction to connect two cpe210 with a router hanging off the client CPE 210?

Here's my problem trying to extend wireless internet connectivity to a building about 1,000 ft away I have two cpes and an ASUS router. My goal is to have wireless clients at the second building connect to the router and back to the main ISP connection point in the other building  using the two cpe210

I have a bunch of tp-link devices I would like to have internet access to.  I think this is possible with the hardware I have mentioned above however I can't seem to get it to work can someone point me in the right direction or to a good thread that explains how to set this up many thanks in advance

Cpe210 in Access point configuration  ==> to cpe210 in client configuration ==> with router plugged in to client cpe210  to serve up Wi-Fi access to clients in the second building.
