How to Set Up a Wireless Hotspot - From Ethernet (Windows 7)

Step 2: Step 2: Configuring the Microsoft Virtual WiFi Miniport Adapter.

This step will guide you through configuring your newly set-up Microsoft Virtual WiFi Miniport Adapter.

This step will walk you through the process of creating a wireless hotspot using a pre-existing wired (ethernet)  internet connection.

To begin with, if it has not already been done, plug in an ethernet cable into your PC's Ethernet port. Then Navigate to "Network Connections" (From the Network and Sharing Center click on the "Change Adapter Settings" link in the top left hand corner. Enable the virtual adapter, if it is not already enabled, by right clicking on the adapter and pressing enable.  Once you have internet connectivity via the Ethernet cable and the virtual adapter is enabled, right click on the "Local Area Connection" button and click "Properties". Once the dialogue box pops up, click on the "Sharing" tab. From here click the check box labeled "Allow other Network Users to connect through this Computer's Internet Connection". Click on the Drop down box "Home networking connection" labeled "Select a private network connection" and select the Microsoft Virtual WiFi Miniport Adapter which should be labeled "Wireless Network Connection 2". Click "OK" and the "Local Area Connection" button should now say "Shared".

The first time I tried this it worked like a charm. Everything went as described. But that was a test. Now I am trying to replicate it on the same windows 7 laptop but instead of using the LAN card I am trying to use a mobile broadband card in the same computer. I am traveling and have a connection to internet via a service provider in the country I am in. When I tried to start the hosted network I got an error "a device connected to the system is not functioning". When I right click the main wireless connection I get several options not available in the miniport including "bridge connection" and "diagnose". Choosing diagnose I get windows does its thing and tells me that the wireless radio is off (for some reason I have to keep turning it on manually) and turned it back on for me. Now that it is on, the start hosted network command returns the following error:
"The group or resource is not in the correct state to perform the requested operation."

Once possibility is that Lenovo installed something that manages some network connections like wireless connections ("manage wireless connections", displacing the native windows versions. I have no idea how to turn this off and worry that it may be mucking about with some settings and not letting me control it.
Any hints on why this works with a network card but not a mobile broadband card?
