I purchased my Cafe double wall oven months ago, and have yet to be able to connect it to wifi to access any of these features.  This is despite my tireless efforts, and being reasonably capable with these things (as I am an executive with a technology company).

I have called tech support no fewer than 10 times and each and every time I call they assure me someone from the tech support team will get back to me via email and this never happens.  They just ignore me as a customer.  It is truly shocking.  

If GE/Cafe is going to venture into wifi enabled devices, they simply must develop equipment that is useable and customer service that is capable.  They have done neither of these things.

As an oven, it is handsome and works well (without wifi).  But I cannot warn you strongly enough to stay away from this if you expect to have the wifi functionality.
