Hello,

I already mentioned an issue concerning mobile broadband in this topic:
3G dial up connection properties changed/no automatic connect
and here
3G dial up connection properties changed/no automatic connect - Microsoft Answers

Now I have Windows 8 Pro RTM installed and still have the same issue.

I found the following website:
Engineering Windows 8 for mobile networks - Building Windows 8 - Site Home - MSDN Blogs

What I am looking for is my Huawei EM770W to pop up as:
Click image for larger version and
Click image for larger version
and
Click image for larger version

But instead it just looks like:
Click image for larger version

And in the "Networks" charm I see a telephone icon next to the connection of which I think it is broadband. I can't even find that icon on Google.
I can only view the properties of the connection. That brings me to the desktop view and the standard Dial-Up settings.

The main issue is: I have HAD the Huawei EM770W work like that! It just doesn't do it anymore. Now I cannot set this connection to automatically connect. Basically: I cannot use the advantages for Mobile Broadband that Microsoft has built in Windows 8!

I would really appreciate some assistance here!
