Also, since my current drive is running Yosemite, it seems that is what OS Recovery would install. I can connect to the wifi, but not to the internet through this manner, and I don't have easy access to the router or a wired connection.
But I am in a building with a shared wifi, and apparrantly there are limitations to what type of wifi security works with internet recovery. Original plan was to use Internet recovery to load the system onto the new drive. My current drive is still running Yosemite, so was planning to do a clean install of High Sierra on the new drive, and then migrate my data from the existing drive to the new SSD. My existing startup drive is in bay 1, and the formatted but empty SSD is in bay 2.
I added a new SSD drive to my mid-2010 Mac Pro, and want to do a clean install of latest OS, but keep hitting snags.
