you like to complicate things, by your answer its understood from your ISP you have a modem plus a router plus a AP, models of the 3 devices would be great, as Im not in the guess telling business yet

According to your description,your goal is easy to be achieved with two CPE510s.
The topology is as follow:Internet---Modem---router---CPE510A(Work on the AP mode) )))(((CPE510B(Work on the AP Client Router mode)---router(Wired or wireless is OK)---device
As above,you should first connect your CPE510A to the router(With internet access) in wired connection and configure it on the AP mode.Then,put it up as high as possible outdoor.
At another house,place the other CPE at the same height that the two CPEs have a LOS clearance.
Finally,configure the CPE510B to work on AP Client Router mode and connect it to another wiless router to cover WiFi signal.
In this case,you may have to purchase a new wireless router.
