Wifi issue when connecting to an AP CC3200 Launchpad

Hi there,

Hoping someone has some insight on this rather strange issue.

Sample code is the Wifi Connect with WPA example:

WiFi.begin(ssid, password);
  while ( WiFi.status() != WL_CONNECTED) {
    // print dots while we wait to connect
    Serial.print(".");
    delay(300);
  }

Basically what will happen with my launchpad cc3200, is that this will work once, then the next bootup, the code will hang after a varying number of '.' are printed to the serial connection.  If i then reset it again it will work. alternating, as far as i can tell 100% of the time.

I've seen the thread about the AP->STA->AP mode fixes and nothing I tried from that thread helped.

I've got an pre-production launchpad CC3200, not sure where to get the versions, but I flashed the latest service pack firmware following the energia guide for doing so.

Edit: I'm running energia 0101E0015, on mac OS X Yosemite, I performed the firmware flash in a windows 7 virtual machine.

Thanks for any insight you can provide
