I'm on windows 8 and couldn't get Putty to work either but i did with using the Arduino IDE:

> **[Software](https://www.arduino.cc/en/software/)**
>
> Open-source electronic prototyping platform enabling users to create interactive electronic objects.

and following the helpful instructions here:

> Yes, you need to send an endline character to get the SSID. In puTTY, pressing enter will give you an endline character, but in Arduino there’s a drop-down menu that determines what the enter key does. I don’t have hardware with me so I’m not sure...

basically select newline in the drop down menu before you type in teh SSID and click enter.

I found though that in order to connect to the cores after i got them to work via USB was to go into the app, let it to try and connect to them and then click back in the top left, it loaded tinker and i could see the cores. But thats on Android, can't imagine its too different on iOS.
