Why is my device automatically joining HWS-Public after I've configured and connected to HWS-Private?

If your device is set to remember previously joined wireless networks, it may join to HWS-Public before HWS-Private

If your device is set to remember previously joined wireless networks, it may join to HWS-Public before HWS-Private. Go to the wireless settings on your device and "Forget" HWS-Public.
