Then he checked some stuff & said it was that the Wi-Fi card in my computer was getting such a weak connection, that is what happened. I know what Wi-Fi is but I've only had an inexpensive desktop computer and I didn't even know a w-fi card was in there....I've never used Wi-Fi & I don't have a smart phone, etc.
I ended up with the some Wi-Fi thing he put on top of the computer (was a NETGEAR a-6200 Wi-Fi USB adapter.) It solved the problem...and Wow...I didn't even need to get into this long preface!
I didn't find the right solution from the Internet.
