I've been absent from this forum for some time. I came very very close to scrapping RP altogether and going with Digitrak. I tried all the suggestions from you fine folks, and got to the point that I was embarrassed to keep coming back. So I got with Tim Ring and we went round and round with suggestions that didn't work, then I just put it on the back burner as I had other issues to contend with including the death of a family member and all that entails with me being his POA.
There was one suggestion that Tim gave me that I tried when the opportunity came up, and that was to try a friends internet connection. After several vain attempts I was finally able to download the RPAssistant. Then I tried to download a sound file, and that's when I noticed that I needed to have the HC connected as well. I had to suspend that until I could make arraignments to go back to his house again.
Yesterday I had a chance to try again. With a fully charged HC, my notebook, and the USB cord, I connected to his Roadrunner WiFi, I tried again to download a sound file. Again and again my attempts to connect to RPA failed, then finally I connected. I picked a file, it showed up on the list, and after plugging and unplugging the HC at least 8 times it finally started to download the file. It SLOWLY got to 15% when I noticed that the HC said it was not connected, so I unplugged and plugged it back up and that put the stops to the whole thing. At about that time his daughter called and needed help as she had no water in the house, so he had to rescue her and I had to leave.
So that's where I stand now, only slightly less frustrated than I was before, and still without the desired results.
