    Can someone help me with this blue screen I get when I connect to one particular WIFI network.
    I have attached minidump and system info files.

    Thank you,

  • Hi,

    All of the attached DMP files are of the DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) bug check.

    This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.

    A driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high. This bug check is usually caused by drivers that have used improper addresses.

    ^^ Intel® Wireless WiFi Link driver was the problematic driver. However, despite being the problematic driver, it's not the true cause, and something else (3rd party) is causing conflicts.

    After taking a look at your modules list, I see the following:

    0: kd> lmvm mdmxsdk
    start             end                 module name
    fffff880`054a9000 fffff880`054ad280   mdmxsdk    (deferred)             
        Image path: \SystemRoot\system32\DRIVERS\mdmxsdk.sys
        Image name: mdmxsdk.sys

    ^^ Conexant Modem Diagnostic Interface x86 driver. The device driver date (2006) is too old to function with the OS, and that's the problem with many of these modems.

    Overall, you are unfortunately going to need to purchase a newer modem with more up to date drivers if no driver update is available - http://www.conexant.com/support/
