Ecarfan,
I called Tesla the next day. The help was courteous, but it took a couple of transfers to find the right department. The person was fantastic in holding my hand. It appears that my internet connection at home does not work very well. It keeps bouncing back and forth from my personal internet to another signal that is in the neighborhood.
Anyway, she had me deactivate the internet connection so that the 3G bars were visible at the top of the large touchscreen. Presto! It worked.
You might try this technique, Fan.
