I can still setup WiFi via USB.
I’ve tried the spark app, the TI Smart Config app.
Tried it on an iPad 3, iPhone 5 and iPhone 4S.
Tried it on my standard Airport Extreme network, and on a newly created Guest Network.
The spinner just spins forever, or eventually states “no cores found”.
This was originally working when my first 2 cores arrived.
Also, I cannot (via USB) connect one of the cores to my Guest WiFi Network, yet I can connect it to my normal network. If I leave it on the standard network I get CFOD within a couple of hours. I want to move it temporarily to the Guest network, as another core which was experiencing CFOD on my main network is now behaving correctly on the Guest Network.
I didn’t expect this to be so complicated!
