WiFi access point - disabling and enabling WiFi Client

I did access point on my TX2, enables SSID Broadcasting, auto connect and all worked fine.
Now i want to connect TX2 back to the local hotspot (WiFi) as a client.
The WiFi card seams not search for WiFi, looks like it remain in AP Mode.
In network manager all AP have been removed.
Any idea how to deal with it ?
