I’ve a multifunction PCI device that handles different devices, one of the device has a wireless modem. The driver provides IOCTL for configuration and data transfer to/from the device. The client wants the device be exposed as a Wifi device 802.11g; they want to use Window 7 standard wireless networking features and network API in .NET. I never worked on network drivers but did many PCI/USB/ISA drivers. Is it doable? If so could anybody provide some architecural hint on how to proceed?

Is the wi-fi function based on some well-known wi-fi controller (ex.
Realtek, Marvel and so on)? Then you just make it a separate PCI
function, as per the PCI standard, and use the driver provided by the
wi-fi vendor.
This function will work as standalone wi-fi controller, with complete
Windows support.
If it cannot be done as a separate PCI function, but has a separate BAR,
try to use the Windows multifunction shim (mf.sys) and hope that the
vendor’s wi-fi driver can work in this configuration.
Otherwise, it is not feasible for you. A wi-fi driver from scratch
(without the embedded firmware) takes almost one man-year for
experienced developer.
Thanks for the answer.
It’s not based on wi-fi controller; the solution is sort of making a virtual wifi driver without a wifi controller; seems not feasible.
I would guess the interesting work is mostly in the firmware. The host
driver is mostly translating requests from one to the other, as boring as
usual-

Yep, the host part is mostly boring OIDs. Ah, and hooks for test
automation and the whole WHQL thing And all the bluescreens are yours
