I bought cpe220 just few months ago. And worked fine with receiving signal from other cpe2xx and nanoStation products. But today I tried to connect it to home wifi router model (d-link 2740u) placed nearby my home with hidden ssid and wpa2 password encryption. And my cpe220 configured in (AP client router mod+dynamic Wan ip) all the wireless information configured correctly but my cpe220 connect to d-link wireless signal for few seconds then  disconnect and again connect and disconnect in loop over and over I tried client mode, messing with cpe220 wirless parameters, static wan ip, lock to AP. Nothing work. I also changed all d-link wireless settings. But noticed that the only thing that keeps the cpe220 connection hold is enabling the "ssid broadcast" in d-link router

Is there any solution without enabling "broadcast ssid" option in the d-link router??
