    I am working currently on the fixing of the WLAN driver for Philips BGW200 chip for Windows CE 5.0. The WLAN chip is connected to the CPU Intel PXA270 via the SPI interface.

    We experience device freezing (during roaming?) in wireless environment with 17 access points and Cisco WLAN controller. The threads and timers of the driver are sequentially crashing or stopping somehow, the WLAN chip stops to send interrupts, and NDIS stops to query and set configuration data to the driver. Even reset of the driver invoked by NDIS doesn’t help.

    We do not have any documentation for the driver and the firmware is only a binary image. We have discovered many synchronization issues inside the driver and some memory leaks are also present.

    If you can, please help us. Is there any available developer documentation for the BGW200 chip, or for any Windows CE driver for it? Is there a tested and well running driver available?

    Any advice is welcome.
