Bill mentioned to me that the WiFi modem screen has a figure in the bottom left hand corner which seems to be the WiFi download measurement. I did a little test on this the other day - when I looked it had the entry 0.03 MG; after two hours working with a member introducing them to the U3A website using the 'Treasure Hunt' resource and with a few searches on my mobile, the modem screen registered 414 MG. I will do this again on a few other occasions. Food for thought in deciding on the best option.
It seems most of the Tech Heads are going to be away - United States, Tasmania or 'grey nomading' for the October meeting. Have a wonderful time!
