Merge two question on connections with Control Channel Trigger built up over SoftAP on Connected Standby PC

Question

Let me clarify my question & some new phenomenon:

I think , For PC which supports Connected Standby, if the connection is over softAP, the control channel trigger function are not well implemented by Microsoft.

As Microsoft documented, " Only systems with network devices that support connected standby will have a hardware slot. " but when I allocated Hardware slot on system that support CS, the ControlChannelTrigger.WaitForPushEnabled  always return SystemError.

So First Question is : why can not I allocate Hardware slot on machine which support Connected Standby?

Then I have to manually reallocate Software Slot, this time it works. But when I call ConnectAsync, it will always take 21 seconds to return. (If my connection won't go through softAP, it won't take more than 1 seconds). if i remove the selection the capability of internetClientServer, the call to ConnectAsync will soon return. But my app do need the capability to be internet client & server.

 So Seconde Question is : why the ConnectAsync take 21 seconds to return if select capability of internetClientServer over softAP on Connected Standby machine ?

If these functions (connected standby, soft ap, control channel trigger) need network device driver / hardware support, please let me know.

Thanks so much for all your suggestions.

Hello,

My Metro app need to use StreamSocket to do connection & send/recv data.

but if I select Capability of internetClientServer, my ConnectAsync will always takes 21 seconds to return,

if i do not select the Capability, it will soon connected, but I can not send/recv properly.

The connection is using SoftAP built up with HostedNetwork.

My computer support Connect Standby, Win8.1+Atom CPU+32bit OS+X64-based processor+ Broadcom 802.11abgn wireless SDIO Adapter.

It only happen on this config. the app works well on other pc.

Please help to check if it is a Microsoft BUG.

Thanks so much.

The best way to troubleshoot this issue is to collect a Network trace using tools such as Network Monitor or Wireshark and analyze it. All that ConnectAsync does under the hood is perform a name resolution of the target you are trying to connect to and then establish a TCP-IP connection with the remote server. The capability is just used to check whether you can perform a certain operation or not and is more like an access check/ security setting to allow/disallow certain operations.

Please do not post multiple threads for the same problem.

I am going to suggest you open a support case to investigate into this further.   

You may already have support cases associated with your developer account so you can use your developer account to open a support case.   

1.)    Visit the URL: http://aka.ms/storesupportwith your developer account.  

2.)    Towards the bottom of the page, there is a link that says “…contact us immediately.”  

3.)    Click that link and then it will ask you to choose the support type. To reach the correct support team choose the following:  

a. Problem Type: “Technical support for Windows Store and Windows Phone app development” 
b. Category: “appropriate category" 
c. Once you do that, there should be an option that lets you “Request a call”/ “Start Email”
