    Dell Latitude E7450 Wifi driver causing BSOD


    Hey all,

    I have a user with a Dell Latitude E7450 that has recently In-Place Upgraded to Windows 10 (from Windows 7) and ever since the upgrade, her Wifi blue screens when running a speedtest from speedtest.net. (Or presumably after any extensive Wifi use) I have tried updating the drivers from Windows Update as well as from Dells website and the laptop is certified as being Windows 10 certified.

    Thanks!

    Latest dump indicates a problem with bcmwl63a.sys
    Code:

    Probably caused by : bcmwl63a.sys ( bcmwl63a+150c7a )
    That belongs to Broadcom 802.11 ac, the wireless device, which is actually the Dell Wireless 1560 802.11ac

    The installed driver is dated Mon Nov 23 17:56:21 2015.
    The Dell web site shows one dated 06 Jan 2016

    Code:
    Dell Wireless 1550/1560 WiFi Driver

    That was the file I downloaded from Dell's website, (I downloaded it again and connected into her machine to install again to verify)

    The version matches so that appears to have been installed okay. Lets wait and see if another problem occurs. If it does, run DM_Log_collector again and upload the zip file.

    She has still been getting blue screens, that was also the driver I had installed before, here are the latest DM log collector logs.

    Thanks,

    Still the same problem:
    Code:
    BugCheck 1000007E, {ffffffffc0000005, fffff80164510c7a, ffffd000252946d8, ffffd00025293ef0}
    
    Probably caused by : bcmwl63a.sys ( bcmwl63a+150c7a )

    Notice the date on the driver is still Mon Nov 23 17:56:21 2015 which does not match what is on the Dell site.

    I downloaded the driver from Dell then expanded it and bcmwl63a.sys is not in it. Now I'm totally confused.

    Almost identical problem here: BSOD on Windows 10 [Broadcom 802.11 Wireless Driver, bcmwl63a.sys] - Windows 10 Forums

    Resolution was to backup data then do a Clean Install. What are your thoughts on doing that?

    Thanks for checking everything out, unfortunately Its a remote user that's having the problem so I think she will end up rolling back to Windows 7 the installation.

    Thanks,

    Probably the best choice. Some things are difficult to work on remotely.
