Pan & Tilt Camera

this camera is not connecting to my wifi router…It was working fine and I removed from my account and let my friend used it and he was able installed successfully in his home.
Now when I tired to install to my router , it could not pair with my linksys router, I did reset, power down and followed the procedures. I have 2 others and both are working fine.
The instructions on the Zink Connection, the procedure #4 shows home network and ZMD_SAP
so on procedure #5, I selected ZMD_SAP and it knocks the internet connection down.

so what the deal? any suggestions?

Turned out that it is a defective camera and sadly I have to send back. Wasted my $$$$ on postage that they did not reimburse

A lemon!!.
