Reading through all the posts about 7.0.1, it seems that there are a number of weird, inconclusive seemingly random fails.
One thing I did not try (but will today) is to pull power shortly after the Configurator applies the Ethernet configuration (right after selecting the account).
I am not sure that this will have any affect, but at this point I am ready to try anything.
I will also verify the account, as well as try one more “fresh” account.
I am using 7.0.1 exclusively at this point, since I only have 7.0.1 & 7.0.0 images (but I just downloaded 7.0.2 & 7.0.3, so I will try those).
I have three different MicroSD cards, 3 Raspberry Pi’s two Farmduino’s (one may be compromised - will only used as last resort).
I have set up mobile hotspots with both iOS & Android - FB fails to connect to either.
As one more debug step, I will see if I can find some other basic Raspberry Pi network connection routine, just to rule out Configurator problems.
