hi all, I am having a bit of a nightmare with a Dell Precision M6500 machine running Windows 7 Pro x64 SP1. Basically whenever I reboot/shutdown the machine the WiFi NIC gets disabled. Machine has: Ethernet NIC: Broadcom NetXtreme 57xx Gigabit Dell Wireless 1510 Wireless-N WLAN mini-Card - Both NICs have “allow the computer to turn off this device to save power” disabled. - WLAN-AutoConfig service reports on eventvwr, which I suspect could be a driver issue. EventID 10002 WLAN Extensibility Module has stopped. Module Path: C:\Windows\System32\bcmihvsrv64.dll However I have used the latest drivers from Dell, but still no joy I kinda of run out of ideas really. Help is appreciated C:\>netsh wlan show drivers Interface name: Wireless Network Connection Driver : Dell Wireless 1510 Wireless-N WLAN Min Vendor : Broadcom Provider : Broadcom Date : 21/01/2010 Version : 5.60.48.35 INF file : C:\Windows\INF\oem13.inf Files : 5 total C:\Windows\system32\DRIVERS\BCMWL664.S C:\Windows\system32\bcmihvsrv64.dll C:\Windows\system32\bcmihvui64.dll C:\Windows\system32\drivers\vwifibus.s C:\Windows\system32\bcmwlcoi.dll Type : Native Wi-Fi Driver Radio types supported : 802.11n 802.11a 802.11g 802.11b FIPS 140-2 mode supported : Yes Hosted network supported : Yes Authentication and cipher supported in infrastructure mode: Open None Open WEP Shared None Shared WEP WPA2-Enterprise TKIP WPA2-Personal TKIP WPA2-Enterprise CCMP WPA2-Personal CCMP WPA2-Enterprise Vendor defined WPA2-Enterprise Vendor defined Vendor defined Vendor defined Vendor defined Vendor defined Vendor defined TKIP Vendor defined CCMP WPA-Enterprise TKIP WPA-Personal TKIP WPA-Enterprise CCMP WPA-Personal CCMP Authentication and cipher supported in ad-hoc mode: WPA2-Personal CCMP Open None Open WEP IHV service present : Yes IHV adapter OUI : [00 10 18], type: [00] IHV extensibility DLL path: C:\Windows\System32\bcmihvsrv64.dll IHV UI extensibility ClSID: {aaa6dee9-31b9-4f18-ab39-82ef9b06eb73} IHV diagnostics CLSID : {00000000-0000-0000-0000-000000000000}

What does Dell support have to say? You have the business support for this machine. You have the latest drivers. Start a ticket with Dell. Is there a Dell Control Point setting that turns off the wireless? Check a BIOS setting for the device? Are you using the A06 BIOS from Dell? http://support.dell.com/support/downloads/driverslist.aspx?os=W764&catid=1&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=PREC_M6500&hidos=W764&hidlang=en&TabIndex=&scanSupported=True&scanConsent=False

Hi, Thanks for the post. As Nano says, please try to update the BIOS first. Also, you may refer to the following article. http://technet.microsoft.com/en-us/library/dd392896(WS.10).aspx If the issue still occurs, please contact your computer manufacturer, or the manufacturer of your wireless network adapter for the most recent adapter drivers.
