Hello, I have three CPE510s that I need to use to extend my wifi over a dam to the tailrace. The first one at my office is the AP. I have two more at the top of the dam connected to a switch to get the signal over the top of the dam. My question is, how do I configure the other two on top of the dam? Do I make the closest on to the AP a client and the one facing the other way a repeater? Do I make them both repeaters? Any help would be appreciated

I guess that you want to configure the topology like this：CPE510(AP))))))CPE510(Repeater))))))CPE510(Client)-------switch

I don't recommend using CPE as a repeater, because as far as I know, CPE's antenna is on the front side, that is, only its front side can normally receive and send signals. If CPE510 is used as a Repeater, we can only face it toward the AP or Client, this signal may not be good.

So I suggest you set CPEs like this: CPE510(AP))))))))CPE510(Client)-------switch

The coverage distance of CPE510 is 15km, so the distance should be sufficient.
