http://stackoverflow.com/questions/14119557/connect-to-the-specified-configured-network-programmatically

the key is:

        mWifiMgr.disconnect();

        mWifiMgr.enableNetwork(wifiConfig.networkId, true);

        mWifiMgr.reconnect();

and determining if the connection to the AP is established:

                ConnectivityManager connectivityManager = (ConnectivityManager) 

                        MyController.mContext.getSystemService(Context.CONNECTIVITY_SERVICE);

                

                if (connectivityManager != null){

                    networkInfo = connectivityManager.getActiveNetworkInfo();

                }

                

                if (networkInfo != null && networkInfo.isConnected()){

                    Log.v(TAG, "CONNECTED!! detailed state = " + networkInfo.getDetailedState());

                    break;

                }

                Log.v(TAG, "not connected!! reason = " + networkInfo.getReason());
