Hello again samyak.  You are very welcome!
The first device (the virtual adapter) is virtual network which allows you to use the computer as a "software router."  Unless you're using this PC as an Access Point this device is useless to you.  This article has more information on the service.  Your best bet is to just disable it.  Try the following.
Click Start, go to "All Programs," and select "Accessories."
Right click on "Command Prompt" and select "Run as Administrator."
Type the command "netsh wlan set hostednetwork [mode=disallow] and press Enter.  This should disable the virtual adapter.
Exit Command Prompt, reboot the computer, and verify that the device is no longer listed.
The device with the "ACPI/HPQ0004" ID actually returned two results.  The first was the Quick Launch Button software.  The other was related to Hard Drive Protection.  Try this driver.
Make sure to reboot after all of these instructions have been completed.  Then go back to Device Manager and verify whether everything looks as it should.
Continue to have a great day!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"

    Hi:
    HP does not provide any support for previous operating systems on their consumer PC's which is why there are no W7 drivers for your model.
    Below are the drivers you need:
    1. Bluetooth Controller:

  • Driver needed for Network controller,PCI Device,SM Bus controller

    Need helpt to get the drivers for win 7 64 bit for Network controller, PCI Device,SM Bus controller, Universal Serial Bus controller, PCI Encryption/Decryption controller

    Hi: For the smbus and usb 3 controllers, download and install the amd chipset drivers and reboot. http://support.amd.com/en-us/download/chipset?os=Windows%207%20-%2064 PCI device: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-141812-1&cc=us&dlc=en&lc=en&os=4063&product=7174407&sw_lang= PCI Encryption/Decryption controller: Download and run this driver.  Then you have to manually install it. http://h20566.www2.hp.com/hpsc/swd/public/detail?swItemId=vc_133833_1 To manually install the driver, go to the device manager, click on the PCI E/D Controller needing the driver. Click on the driver tab.  Click on update driver.  Select the Browse my computer for driver software option and browse to the driver folder that was created when you ran the file. That folder will be located in C:\SWSetup\sp66974. Make sure the Include Subfolders box is checked and the driver should install.   Then reboot. Network controller...need the hardware ID for that because I don't know what model wireless card your model has. Since there is no wireless driver installed, there should be a device labeled Network Controller in the device manager under an Other Devices category.  The network controller device will have a little ! mark next to it. So, find the network controller device, click on that and then click on the Details tab. Now you see a Property drop down list and it is defaulted to Device Description. Drop down on that list and select the third item (Hardware ID's). Post the top string of characters you see in the window.

  • HP Probook 4440s WIFI Drivers Not Working After Windows 10 Update

    I updated my Hp ProBook 4440s from windows 7 32 bit to Windows 10 32 bit, everything is working except for my WiFi it says 'Windows did not detect any networking hardware' Can you please provide me with the compatible wifi drivers for Windows 10 Pro 32 bit. I hope you can help

    Hi: I guess what I meant to say is that you may want to play around with some of the advanced settings for the card in the device manager. It seems that reading the article you posted, that procedure may have been for folks that have Cisco software to allow for Virtual Private Networking (VPN) and I don't think the drivers you have include any Cisco extensions. You can see if there is Cisco networking software by going to the Programs menu in the control panel and see the list of programs installed. There are usually 2-3 Cisco networking software items listed if you do. Sometimes tweaking those advanced settings help.  Here is an article that explains what some of these settings are for. http://superuser.com/questions/342759/can-somebody-explain-about-wi-fi-device-manager-settings-and-power-settings-in-w The ones I normally change are:  Enable WMM.  Set Roam tendency to conservative.  Roam decision to optimize distance. I had to change some setting on an old Intel 5300 wireless card to allow it to connect in W10.   The drivers were there, etc but when I went to connect to a network, it did nothing.

  • TS1398 when i update my software to 6.1.3(10B329)to I phone 4s the wifi is not working and not auto join the network that i have already connected to

    when i update my software to 6.1.3(10B329)to I phone 4s the wifi is not working and not auto join the network that i have already connected to

    First, grow up.  Just because YOUR phone isn't working, doesn't mean Apple put out bad software.  I've not had any difficulty, nor has anyone else I know.  And just how is Apple risking lives with Bluetooth kits not working?  It's YOUR decision to talk on the phone or text and drive.  Not Apple's.
    We're users here, volunteering our time to help others.  Posts like yours, which are whiny and ranting, simply means we're likely to ignore you and not provide you with any help.  Not to mention, it makes you look absolutely foolish.
    Further making you look foolish is the fact that you haven't even asked a technical support question, nor have you provided anyone here with any troubleshooting steps you might have taken, including those recommended in the user guide.
    Good luck getting help.

    If a restore did not fix it, you have a hardware issue--possible bad wi-fi radio.

  • Network drivers not working and Windows Error Recovery Message issues

    I have a ThinkPad laptop T530 series in which about five of my network adapters are showing the exclamation mark in a yellow triangle next to them. When clicking on properties, it states that" this device will not start--code 10." I have tried the network sharing troubleshooter and this has not worked.
    The second issue I am having is that upon starting my computer I am constantly getting a Windows Error Recovery message which I have to press on the proceed to Windows as the startup repairs do not seem to rectify the issue.
    I would very much appreciate if someone could help me resolve these issues

    I don't have a solution to your main problem, but I have one for the error message.
    If I am right, then Airport is causing the problem. 192.168.1.1 is the address that the Airport Base Station will take right away. To fix this, you need to go into Airport Admin Utility. Click on your base station and click "Configure." Click on the "Network" tab. Now it should look something like this:
    http://i198.photobucket.com/albums/aa187/adam_0/Network%207-28-07/Picture2.png
    The problem is that the Airport is using the same IP number set as the router that you have. If you disconnect or unplug the Airport, then that would fix it easily, but if you want to keep your Airport connected, then all you need to do is pick one of the other number formats, like this:
    http://i198.photobucket.com/albums/aa187/adam_0/Network%207-28-07/Picture4.png
    Now, I'm no expert on this stuff, but from what I understand, this could get you one step closer to your destination. Good luck!

  • 2011 MBP with Win7 on BC and numerous drivers not working

    I'm working on a tech project and have run into a problem that i can't fix. <grr> I followed the Apple directions for installing a second OS on Boot Camp and found some good tips from other online walk throughs, but am still having a problem with a number of the drivers.
    I have a 2011 MacBook Pro 13" with the most up to date version of Snow Leopard. I have installed Boot Camp and Windows 7 Pro on a 50 Gb partition. I have installed Windows 7 and activated it. Once Win7 was up and running I updated the Boot Camp drivers with 3.2.0, the latest version that I know about. Initially I had no recognition of either the wired or wireless controllers even after the Boot Camp 3.2. I was able to determine that I had a Broadcom wired ethernet card and found the driver and installed it via USB so that I could use Win7 to access the internet.
    The drivers that, as found from the Device Manager, are not working are as follows:
    Network Controller - Wireless
    PCI Simple Communication Controller
    SM Bus Controller
    High Definition Audio
    Apple Keyboard -> Bluetooth USB Host Controller (though the USB ports are active and operational)
    Facetime HD Camera (1 of 2 not working)
    I have been able to use the wired internet to download and install all of the available Win7 updates, but nothing can be found on the above drivers. I even manually installed the drivers for each of these components from the Snow Leopard disk for Boot Camp and they would not install.
    From all the information that I can find on the Win7 Boot Camp install, nothing more recent than early 2010, everyone seems to have everything just install and work. I have not seen anything from anyone about the wireless and wired network cards not working or any of the other issues that I'm having. The majority of the issues were with the optical audio LED staying on or some other more trivial issue.
    Anything you can suggest would be great so that I can use the internet in Win7. The rest of the drivers are second to getting on wireless.
    Thanks in advance for your help. If you have any more detailed questions please let me know and I'll get answers back.

    I have a 15" MacBook Pro, built July 2011. It came automatically with Lion. No OS X disc provided in box with Lion, due to it being a download only OS.
    I followed the boot camp process to partition the hard drive and format the appropriate partition, to then install Windows 7 Pro Upgrade (clean install - works fine). Just like the original post, the following drivers that will not install properly include:
    - trackpad
    - keyboard
    Even when trying to re-install the drivers again manually off the boot camp disc, a window pops up to stating that the drivers may not have installed properly and gives you the options to either re-install the drivers 'using the compatability settings', or 'no the drivers installed ok'.
    It's almost like it thinks Windows 7 is an old program....weird.
    The keyboard and trackpad is missing from the Boot Camp control panel, so I can't change the settings for the keyboard and trackpad, to get them functioning the way they're meant to - like it does in Mac OS X.
    I thought that this page would help: http://www.reviewmylife.co.uk/blog/2010/06/08/windows-7-on-macbook-pro/ but no it didn't. The boot camp control panel screen dumps shown in this link, looks nothing like mine, due to the fact that the drivers refuse to install properly.
    I have spent hours trawling many mac and windows forums with not luck.
    Anyone with a MBP running Lion OS and Windows 7 Pro have these issues?
    Does anyone have a solution?

  • I have i phone 4s i there is problem of wifi my wifi is not working when i go to the wifi there is no working on off when i update it as a 6.1 ios on that time again it was good but after 2 days again the same problem i am too tired

    Sounds like the device was dropped at some point and damaged as a result.
    Take it to Apple for evaluation and a replacement.

  • Wifi does not work correctly on iPad Mini w/ Retina display

    I've found that Wifi does not work properly on the iPad mini w/ Retina display.
    Some background: I own three iPads (iPad mini w/ retina display, iPad mini, and iPad 3rd gen), an iPod touch 5th gen, and a Macbook Air, and use them all frequently with my pocket Wifi router.
    None of them exhibit any Wifi problems whatsoever except for my iPad mini w/ retina display.
    Here are the details:
    In the middle of using Wifi with my pocket Wifi router, the Wifi connection will abrubptly drop, then reconnect. After the Wifi reconnects, it is no longer able to connect to the internet (even though Wifi itself is connected).
    Once the iPad mini w/ retina display's Wifi gets into this state, the following may or may not restore WiFi temporarily:
    Restart the device
    Reset network settings
    Yet, even if connectevitiy is restored, the problem will happen again within minutes.
    When the iPad mini w/ retina display gets into this state, the Wifi on my iPod touch, other iPads, and on my Macbook Air work perfectly fine, so I know the problem is not with my Wifi device or it's connection, but specifically with the iPad mini w/ retina display
    Note:
    The iPad mini w/ retina display never has any issues with my home or work Wifi networks. The problem only happens when connected to my pocket Wifi device. Yet, all of my other iOS devices and my MacBook Air work perfectly with my pocket Wifi device, therefore I know the problem is not with the pocket Wifi device, but with the iPad mini with retina display.
    Solutions:
    Resetting the iPad mini w/ retina display to factory settings does not solve the problem
    Resetting network settings on the iPad mini w/ retina display does not solve the problem
    I have even replaced my original iPad mini w/ retina and got a new one. Yet, the new device exhibits the exact same behavior as the original device.
    Conclusion:
    I know this is not a hardware problem (since it happened with both my original as well as replacement device).
    I know this is not a problem with my pocket WiFi router, since it works perfectly with all of my other iOS devices and MacBook Air.
    Therefore, this must be a software / firmware bug with the iPad mini w/ retina display. Apple will need to fix this in a future software update.
    Has anyone else seen this problem?

    I too have experienced this issue over the past two days... I have a 16gb ipad mini retina, for reference. I bought the device one week ago, and had not experience any issues at all until bringing my device to work. I logged into my work's enterprise level wireless network both yesterday and today, maintained normal wifi capabilities for 2-4 hours each day, and was then randomly dropped, both days. I tried hard resets, resetting my network settings, airplane mode, etc. Nothing has worked. I am still offline on my ipad mini retina.
    My iPhone 5 is sitting right next to my iPad mini retina. The iPhone is currently connected to the same very network, and has been for the past two years. I have never lost connection on my iPhone's wifi, just my iPad mini retina.
    This must be some kind of bug, as it does not sound like a hardware nor network issue.
    Hopefully they fix this in 7.1.

  • Mavericks static ip doesn't on wifi does not work

    MBA 2011
    MAC OS 10.9.4
    Wifi does not work with a static IP address.
    My wifi access point does not have DHCP enabled, and there is no DHCP server on my network. The internet connection is NOT coming my wifi router.
    Every machine on the network has a static ip address and manually configured DNS and GATEWAY to my correct gateway IP. This currently is working on this machine (windows 7), my ipad 2, my xperia phone, my windows xp box, my vista box, and even a virtual pc running windows server which is on my mac.
    But the mac won't connect to the internet, or ping anything including the gateway ip address or any other machine on the ip address.
    how can i get this mac to have a static ip address without having dhcp

    Going to System Preferences -> Network, and selecting Wi-Fi in the left pane.... Questions:
    . does the Status in the right pane show connected?
    . if so, does the Network Name: reflect the name of the network you assume it should be connected to?
    . if so, clicking on the Advanced... button and choosing the TCP/IP tab:
        . is the Configure IPv4 pulldown set to Manuallyh?
        . if so, have you entered in a valid router value (to mirror what you have set on the other working devices), and an IP address which you know is not already in use on the network?
        . if so, when you Ok out of this sheet panel, if you run /Applications/Utilities/Terminal and in that window type "ifconfig" can you find a configured network device with the address information you've entered (likely either en0 or en1)?
    If all as anticipated by here:
    . what message do you see in the terminal window when you do a ping to the access point's address?
    . are you super-sure that address isn't already in use on the network (e.g on a device already on the network successfully and with your MBA's wifi turned off, try pinging the thought-to-be-free address to see if something answers back).
