NDIS Intermediate Driver for 802.11

Hello

Thank you for reading this message.

I am developing an Intermediate Driver for 802.11.
I have problem Binding to the Underlying Miniport.

The NdisOpenAdapter() funtion takes in a Array of supported mediums. I
have given the following mediums array to this function.

1. NdisMedium802_3
2. NdisMedium802_5
3. NdisMedium802_11

I have a 802.11 card inserted (Linksys card), but the NdisOpenAdapter
is binding to NdisMedium802_3 medium. It doesn't recognize
NdisMedium802_11.

In otherwords, HOW DO WE BIND TO 802_11 miniport drivers as an
Intermediate driver?

The NdisOpenAdapter document doesn't specify 802_11 support, BUT
NDIS.H does have this medium supported.

Though I am developing this driver in Pocket PC, NT, 2000 etc. area
help is fine.

ANY HELP is WELCOME and really appreciated.

Thank you
Ganesan

Current Windows system do not provide support for "native Wi-Fi"
(NdisMedium802_11). The 802.11 adapters appear to the system as if they were
ordinary 802.3 Ethernet adapters (NdisMedium802_3);

Bind to NdisMedium802_3 until Longhorn arrives.

If you are working on Windows CE, then the situation may be different. I
think that Windows CE 5.0 DOES include some native Wi-Fi support (perhaps
support for NdisMedium802_11...), but this is the wrong forum for Windows CE
discussions.

Good luck,

Thank you for the response,

It did bind to 802_3 medium (NOT 802_11). But when I FORWARD the NDIS
packets coming FROM upper protocol layers using NdisSend(), it returns
me an ERROR (invalid packet format). So how do we (as an) intermediate
NDIS driver send and receive 802_11 packets over 802_3 bound medium??

Any suggestions?. Any books? Any articles?

Yes I am developing Intermediate driver for Pocket PC 2003(Windows CE
4.2), but you help seems to be on track. NDIS for Windows CE is just a
subset of Windows 2000. If you can suggest how to do it in Win 2000 or
NT, I can translate it to CE(mostly).

Thanx again.

Just some hint and better ask on microsoft.public.windowsce.platbuilder or
other CE NGs.
4.x / 5 use NDISUIO as intermediate driver and zero configure utility (
WZC ) use it to work
with wireless miniports. Check in PB code of NDISUIO how that done

The best thing for you to do is to start with the PassThru NDIS IM driver
sample from the Windows CE Platform Builder. The last time I looked (CE 4.0)
the CE PassThru sample has problems with PnP and power management. However,
it is probably a better place to start then the "Big Windows" DDK PassThru
NDIS IM driver sample.

Forget this. Bind to 802.3 only.

Send OID_GEN_PHYSICAL_MEDIUM (or is it misnamed a bit?) to check whether this
is a Wi-Fi adapter.

It just caused the iPaq to hang completely if the power button is pressed. So,
it was not possible to suspend/resume the device, a soft reset was necessary
after each suspend.

The reason is deadlock inside the resume paths, since CE's NDIS uses a single
thread to handle all power management, which was blocked waiting on a pending
OID (sent by IP stack) inside passthru.

Well

THANX A LOT for the help. I have all the respect for you guys.

I did start with passthru sample. It works simple for 802_3.
But my work involves trapping 802_3, 802_11, irda and Async(Wan).

Looks like passthru is too simple a code to work for other mediums.
Who is really sitting on TOP and BOTTOM becomes a problem.

Since I am an Intermediate driver, I am not going to modify the
packets,
I just want to anayse it and pass it on.

Its getting bit complex than I thought.

I had some succes for IRDA, but the WAN stuff crashed. Its trying to
bind to
PPP, PPTP, L2TP, AsyncMac all at once since all of them are WAN type.
At it halted.

Well I will have to dig deep into their examples from PB.

If NOT

Probably i will have get Microsoft Help on how the "LAYERS STACK UP"
for these
mediums.


Kind of Info To Maxim S. Shatskih
=================================

using the Ndis Query (OID_GEN_PHYSICAL_MEDIUM) I "think" it it will
return 803_3 since thats the adapter it got bound to. If it were to be
802_11 (Wi-fi), then the packets would have gone thru.
"To me" the layers are not sync since NDIS does something which I
don't know.

I will be posting some questions on NDIS IM drivers as I go along.
Please don't mind.

Thank you again for the help
