I use a browser on my desktop (and sometimes on my work laptop) for the Developer Studio - using Ethernet - without problems. Also at times using wifi for my laptop, even using 4g from my phone.
For the wifi-setup on the Fitbit I do have problems, at work we use wifi that requires username/password or a redirect-page, for that I cannot connect the fitbit.
My solution is to share my phone's 4G-network, and connect the fitbit wifi to the phone (which may seem a bit weird, using the fitbit-app to connect the fitbit to the phone the app is running).
