    Windows 8.1 Pro



    iam getting randomly bluescreens,
    first is used Windows 7 Pro and i recived Bsods with Pen_list_corrupt etc...
    i thought my system may just be broken, so i updatet it to Windows 8.1 Pro...

    Now iam reciving BAD_POOL_CALLER caused by NETIO.SYS so i gues its something with my W-LAN Usb Stick or something? Read somewhere that it have something to do with the network connection... iam using an Cisco WUSB600N V.2 W-Lan Stick
    ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY which was caused by Kaspersky Installation, first time i recived this bluescreen, after that i tried to install it again and it worked without problems.

    And i recived a blank Bsod, the log just says "address in stack" -> "ntoskrnl.exe"...

    SF Log is attached, would be great if you could help me... this BSODS are hunting me.
    Most of the BSODs i recive if i close things... things with memory cache i think... VLC - Spotify - Firefox...

    I did a memcheck for 4 hours... 0 errors... seems like my RAM is fine... :-/

    Thx for your time.

    Your Cisco WLAN stick is using the Ralink chip inside it. In fact all the WiFi adapters uses either Ralink, Realtek or Atheroz chips because they are the major WiFi chip makers. First check with the Cisco site for updated drivers. If not available, download the generic driver from "Ralink" site.

    You should remove the "Netlimitter" program at least as a test. Otherwise we won't know whether it is the actual root cause. Once the issue is solved, you can either install an updated version or find an alternative one.

    Since a majority of the crash dumps are blaming NETIOS.SYS, Netlimitter is the primary suspect here. So removing it is absolutely necessary.

    Windows 8.1 Pro says its the RT3572 Chip but MediaTek - Downloads Windows only got drivers for XP 32bit? :-/

    Intel® Driver Update Utility refuses to start... manuell install is the same... he starts the install but closes the programm without any warning.

    The official support page of "Linksys" only lists Win XP, Vista and 7 driver. Windows 8 is not supported.

    WUSB600N Support | Dual-Band Wireless-N USB Network Adapter

    But the Mediatek site lists a recent driver update ( 9/23/2013) which supports XP, Vista, 7 and 8. Here is the download link for that driver : MediaTek - Downloads Windows

    Just enter your E-Mail address at the bottom and the download will begin. Remember to uninstall the old driver completely before updating.
