I am facing a problem with my primo nx. We need to input the phone MAC id to connect with our office WiFy network. I provided my primo nx's MAC ID and found that internet connection is not working after one day because the MAC id of my primo nx has been changed. Finally I found that the MAC id is changing whenever I restart the WLAN of the mobile. :-[ MAC id should be unique and it should not change if I do on/off the WLAN. Please help me.
