Wi-Fi problem with RemoteViewFinder

My Samsung nx300 has a problem with the Remote View connection. When i connect the camera with my Iphone the telephone does not see the connection.

The Wi-Fi name (in my opinion) has a problem: it is "AP_SSC_NX300_0:??" not "AS_SSC_NX300_0:XX:XX".

The Mobile Link work but the wi-fi name is AS_SSC_NX300_0:00:00 without letters or numers.

I don't understad why the wi-fi name in remote view is different to mobile link.

The firmware camera is v1.45 and the lens v1.13.

On Setting->device information there are not any information on connection (or MAC adress).

Help me please!
