Even worse - I thought Zack was part of the Surface team. Is it just me or does this whole conversation thread seem kind of ridiculous? We've got customers complaining and guessing and trying to find workarounds. You are suggesting I contact an MVP and that we try to "hunt some help down." And yet no one from the Microsoft Surface team is willing to communicate here open and honestly and say "Hey folks, we are aware of these problems. This is what we know... And here are some temporary workarounds... Here is what we are doing... If you are having connectivity issues, please submit your computer configuration here..." Why do we need to hunt anyone down? My guess is that Microsoft has a potential recall-situation here and is afraid to own up to the problem.
No one from Surface Engineering is posting in this forum. Zack is part of the "Service Delivery" group for Surface. I can see that they are fixing things for Windows 10, but there has been nonofficial statement if some fixes won't be done until 10 launches. They've done some work on Win 10 to make Hyper-v and Connected Standby compatible, for example. But I agree that the lack of real and honest detailed communication is ridiculous.
I'm personally telling people I know who ask not to buy a SP3 unless they also spend extra money for an add-on USB wifi adapter since the wifi is so undependable. Susan was in Redmond and was looking to hunt down info from the Surface team.
An external USB adapter is the only suggestion I can make as a work around. I know people should not have to change router settings, etc. And I am not holding my breath for fixes and information.
