Wireless Adapters Won't Install - Device Manager Empty

Dec 5, 2012

I've had this problem with my Windows 7 64bit OS ever since it updated a while back (I'm not sure what updates). The wireless adapter that was already installed stopped working, then two successive new wireless adapters (both usb) failed to work as well. The computer just refuses to detect them (although it beeps to indicate it knows a device has been plugged in). A lot of the methods I searched for to fix this issue told me to look in Device Manager, which is empty... None of the methods I've found have worked (Editing permissions etc). I'm tempted to just re-install Windows.

Jun 18, 2012

In Windows Home Premium 64bit we encounter this problem on a machine after trying to uninstall a norton product manually.The norton software led to serious problems of randomly emerging BSODs.As system uninstall did not work we researched a tutorial on how to manually uninstall the soft.t can be found here Enterprise Support - Symantec Corp. - How to manually uninstall the Symantec Endpoint Protection client from Windows Vista, Windows 7, and Windows 2008 R2 64-bitEverything worked smoothly until the last three steps of the routine failed (12.-14We can not uninstall/delete the wireless network adapters as described. After clicking "uninstall" there is the window that asks for confirmation (to uninstall) but after clicking "yes" the device manager window simply refreshes - and the device remains unchanged.

Device Manager Empty In Windows 7 64-bit

Apr 10, 2012

There was a typical long list until recently, and now they're all gone. I was looking for my scanner which isn't being recognised, although the printer (it's an all-in-one HP photosmart 8180) is recognised and will print. I've run driver updates, registry cleanups, and system restore but with no effect.

I got this PC 3 weeks ago. For two days now Several of my devices have a Code 10 on start up. For instance my mouse in the Device Manager window has a code 10 and will not work until I use the trouble shooter and it re-installs the driver. I have tried updating the USB drivers as many recommend but there were no updates. I tried Microsoft's fix it, and it was not fixed.

Acer Aspire One D255E Wireless Card Not Showing In Device Manager

Jan 25, 2013

HeI am at wits end here trying to figure out how to fix this pc. A friend came to me with the Acer Aspire One D255E with a wireless internet issue. The PC is Running Windows 7 Starter 32-bit. I immediately thought "well there must be a switch that she turned off" There is no switch on the computer for the wireless card. I thought "well there must be a driver issue, Ill go to the device manager and update the driver for it". Then when I got to the device manager... Nothing shows up for a wireless lan card even existing in the laptop, but I know it does, because A) It's a "net Book" B) she was using the internet last week. So, I thought maybe it's not showing up because thee computer needs the drivers for it first, which is unusual, but since its windows 7 starter I thought it needed a kick in the rear to get it goin. So i downloaded all the drivers for the PC using a different computer, and installed the different drivers to see which one would work. Well none of them worked, and now im sitting here scratching my head on what to do next. I have scoured the web and seen a few other people with issues like this.

Device Manager Reports Unknown Device & Explorer Crash

Aug 1, 2009

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

Windows 7 Usb Camera Device Shows Up In Device Manager But Not Computer

May 31, 2012

Have recently purchased a small usb inspection snake camera with led light and when testing it plugged it into two desktops computers (one xp pro not sure of the other as it was a network work computer) It automatically loaded the drivers and brought up a screen automatically with the realtime image.(no driver disc came with it). However plugging into my windows 7 64bit sony laptop it signals a connection beep, loaded drivers automatically but wouldn't open or show up on my computer disc manager as an external usb source to click on. It does however show up on device manager as a usb camera and when I unplug and replug in it disappears and reappears so I know I have the right camera (not the lap top webcam inbuilt one that shows USB 2 Camera). Have tried updating drivers automatically and uninstalling it etc. Need it to work on the lap top so it can act as the movable screen for it?
