iPhone App will not see the SMP

I’ve a wireless setup where my iPhone and SMP are clients. When I use the WD iPhone App, it would detect the SMP first but after a while either the app or the phone switch over to 3G and can’t see the SMP anymore.

Does anyone have seen this happening in your setup?

If you are referring to WD Remote, it only works in wifi and should not switch your phone to 3G, try switching off your 3g while using the app.
