Thanks for the reply. I'm not an expert in this though so I retain the right to be confused.
My network access is a little strange.
I'm in a rural area.
There's a Time Warner pipe going to a local radio tower owned by my provider, SuperNet360.
The connection between that tower and my home is via a radio signal transmitted to a receiver on my roof and then down to my Netgear Router.
To eliminate my home network and router I am able to connect my pc or mac, directly via ethernet cable, to the radio receiver.
I saw no difference when I eliminate my home network and router.
I carried out the test to the San Jose server. (I'm in Los Angeles.)
Linear Test was higher @ 8 Mbps
Multithread was slower @ 11 Mbps
I don't know how to interpret this.
