Windows 7 Mobile Broadband ...

All,

I’m trying to add support for Windows 7 Mobile Broadband Adapters to a
LWF driver but am having a hard time locating one. In read the “Mobile
Broadband Changes for Windows 7” document at the following url …

http://download.microsoft.com/download/7/E/7/7E7662CF-CBEA-470B-A97E-CE7CE0D98DC2/MBChangesWin7.docx

… it provides guidelines for test setup for Windows Mobile Broadband
development and states the following hardware requirements …

Windows 7–capable hardware
Windows 7–compliant mobile broadband modem (for example, AT &T USB
Connect Mercury modem or Sierra wireless Compass 885)

… To satisfy the requirements, I purchased the AT&T USB Mercury modem
and installed it on a Windows 7 development system. Unfortunately, the
connection shows up as a Dial-up Adapter in the VAN UI and not a Mobile
Broadband Adapter.

Anyone got a suggestion for me? I’ve already tried adapters from two
different US carriers without any luck. I’d prefer to spend more time
writing code and less time shopping if I can help it :confused:

Thanks in advance,

-Matthew

Just because MSFT introduced a new driver model for “mobile broadband” devices (whatever that means) doesn’t mean OEMs have to immediately (or ever?) adopt it. I don’t think I’ve ever seen such a device that did not simply expose itself as a USB modem.

So, instead of going and buying a bunch of these devices, why don’t you just download the install packages instead, and see what kind of drivers are included…

Matthew,

Do you have a specific interop concern (like framing specifics for RAW IP)?

I have not looked into it specifically but perhaps the LWF qualification
tests in DTM/NdisTest which use the ‘virtual NIC’ harness to inject and
capture test packets can help provide a test-bed.

When you figure this out (which devices support the new model) please do
share you discovery with us :slight_smile:

Regards,
Dave Cattley

You can try to download the Watcher_Generic.msi from here. It should contain the nWWAN driver for Win7.

Yes, that worked! Thanks for this excellent suggestion. The AT&T USB
Connect Mercury modem now works as a Windows 7 style Mobile Broadband
Adapter. My unmodified LWF driver didn’t attach to it so I think this is
a good starting point for development.

Thanks again,
