Unable to get past Setup Assistant

Hey guys,

Strange one. Installed DP1, then immediately installed DP2 using App Store.

Upon reboot, when I'm asked to setup an iCloud Keychain (the Setup Assistant app), it can't connect because for some reason my WiFi is now disconnected.

I can restart but then I lose the ability to setup iCloud Keychain.

I have the Network pane open in a second desktop, but I can't type my wireless password into it, since the focus seems to be on entering my iCloud password in the Setup Assistant.

Any ideas on how I can get past this? Can I cancel, then run the Setup Assistant again?

And yes, I'm a Dev, and an issue has been logged. Running a rMBP

 

Got past it. Had to tether my iPhone to the Mac using USB (having a Network window open in another desktop), then it was able to get past the Setup Assistant.

Still didn't set it up though. At least not in the iCloud pane.
