Hi, 

I have been running a system with one M5 unit in AP mode pretty smoothly and since they are some pretty thick walls in my apartment, I wanted to boost it up with two P7 units. 

When I try to set them up on the existing WiFi network, although I am connected on that network, I get the error message that I'm not connected on the said network.

Can anybody help?

Thanks very much in advance,

Florian
