Wireless driver uninstalled itself, computer laptop cannot detect WIFI

My wireless driver seems to have uninstalled itself. The blue WIFI LED indicator does not illuminate either. How to reinstall the driver without the disc? Someone's done it before, but I don't know how, and they are no longer available to help.

I found the solution. It turns out that the driver has not after all uninstalled at this time. I just went into the Device Manager, clicked on my card wireless network cards, you click on advanced, then antenna diversity and he went from auto to auxiliary voltage

My computer is a dell 1520, and when I tried to turn the WIFI until I solved the problem happened everything he just said no detected network and the blue LED does not turn.

    My HP 14-d010AU cannot detect wifi. His type of wifi 802.11 is (I didn't type b/g/n, it is not mentioned). Windowws 8 OS.

    Model of wireless card: PCI\VEN_168C & DEV_0036 & SUBSYS_217F103C & REV_01

    I tried to install a wireless driver, RTL8188EE REALTEK 802.11b/g/n driver LAN wireless. I downloaded it from the HP website, but when I installed it, it could not be installed. I've tried other programs (MediaTek (Ralink) 802.11 WLAN and MediaTek 802.11 WLAN Adapter Driver adapter) but was still the same problem.

    Also, I've updated the BIOS and it did not help. And I discovered that my HP doesn't have Microsoft Kernel Debug Network Adapter. The network map of kernel debugging Microsoft does matter?

    So, what should I do about this problem? I need a hand here completely!

  • My laptop cannot detect wireless networks after using the Windows Update service. Technical support, very desperate need.

    I tried the direct technical support, but it seemed to have cut. Given that I can no longer connect to the internet on my laptop, I'm with my playstation browser and painfully by typing with the controller.

    My probllem.
    I have an ASUS Intel Core i3 - 2350M CPU @ 2.30 GHZ running Windows 7 home premium. I've selected "Windows Update" in the start menu and proceeded to download and install all updates. Once the updates have been installed, my laptop couldn't detect wireless networks which means that I can't connect to my router and have lost the internet.
    Device Manager indicates 802.11n Wireless LAN Card is working properly.
    Windows did create a restore point before installing the updates, but everytime I try a restore I get the following message
    "System Restore has failed. Your computer's system files and settings were not changed

    System Restore could not access a file. This is probably because an antivirus program is running on the computer. Temporarily disable your antivirus program and restart System Restore.
    An unspecified error occurred during the restoration of the system (0x80070005)"
    "I disabled anti Virus AVG and COMODO firewall only to receive the same message, and it now appears that the restore point disappeared as if by magic, saying system restore ' no. restore points were created.

    I have reset my router but my laptop doesn't detect a network and there are usually 10 in the region and it shows nothing. My router is fine, as I use it now with my playstation.
    Please I really need help, how do I get my laptop to detect the wireless network. If someone could give me a few steps to do, please.

    Most laptops have a switch that turns the wifi radio on or off.  Often, it is a combination of the Fn key and one of the F keys.  It may be a physical switch somewhere on the laptop.  See your manual for details.

    If this isn't the problem...

    What is the brand and model of your router?  Almost all wifi routers also have at least one Ethernet port, you can connect your computer to the router with an Ethernet cable and download the right driver for your http://www.asus.com/support wireless card
    Have you tried to "Roll back driver" in the "Driver" tab of your adapter wifi 'properties' in Device Manager?  At the very least, determine which version of the driver is installed, and compare that to the current version on the asus support site.

  • Upgrade laptop XP on the new home network. Shared for laptop drives. Now computer laptop poster not the zip drives that I plug into the USB ports.

    I have a xp desktop machine, an external hard drive, computer laptop xp and a computer laptop win7 on a network home via my Lynksys wireless router.  My friend attached external desktop.  Then shared these discs on the network.  He shared them as drives E and F.  I can access these drives very well.  The problem is that on the computer laptop xp now when I click on my computer if there is no zip drives or anything else connected to the computer laptop USB ports it does not show them.  If I go into Device Manager, it shows the mass storage device connected here.

    Another thing.  If external that are shared and the desktop machine is turned off the coast, I can click the icon to the desktop and it displays the zip drive, that I plugged.  It's like I need to rename or remap something?

  • Wireless Driver Ralink 802.11 b/g/n WiFi Adapter could not install

    I have a HP Pavilion Dv7 series: product 2CE1452LGF: A1T85UA

    Basically my brother-in-law is the owner of this computer, and it got a virus on it. He came to me to help him. I tried to reload windows on it, but has encountered a problem with the wireless driver not install correctly. I tried several times but I can't get the driver to install. Then, we ordered the HP restore disks and they faliled to restore.

    I ran all three drives together, and it gives a message after running all three and you try to restore the restore has failed. I then tried to run with just the operating system disks and not the third disck with drivers on this subject, and it still does not restore.

    I want to know if anybody out there knows why this wireless driver not can not install. It starts and then just suddenly ends without error message at all. I have disabled the firewall to make sure that was not the issue, and I am running as the administrator.

    I did not much care if the restore has failed, because I have a copy of valied windows 7 Pro on the computer now and it's a not pirated copy valid. I just want to know if there is something out there that will force the computer to take this wireless driver I can use the wireless and get rid of the connection of the wire. Thanks in advance for your help.

    Laughing out loud!

    Something is stuck...

    We will try to go in the back door...

    Click the network controller in the Device Manager.

    Click the driver tab.  Click on set to update driver.  Select the 'Browse my computer for the software method' and navigate to the installation folder that was created when you ran the driver.

    This folder appears in C:\SWSetup\sp57538.

    Make sure that the include subfolders is selected, and I hope the driver will install that way.

    Otherwise, try the driver ralink directly from ralink... second class listed is what you need.

  • Computer laptop AUTO Detection - your product is not supported by this site

    I reinstalled Windows 7 successfully and decided to see if there were updates of Toshiba. The above message has been received. It's never happened before.
    I have aToshiba Satellite L350-277. PSLD4E-00E004MD
    WIndows 7 Edition Home Premium.

    I tried AUTO Detect, I tried to enter the information manually. I enter the family then details series but when I try to enter the ModelNo, L350-227, it is not there to choose. I know I'm correct (UK) web site. It seems that all of a sudden my laptop does not exist. When I reinstalled Windows, I got my connection Wireless running and connected automatically to Toshiba laptop, I got the serial number which is the same as what is on the underside of the laptop.
    Anyone got any ideas?

    >... but when I try to enter the ModelNo, L350-227, he's not there to choose.
    If you access section carefully, you will see that there is no option for the name of the template, just for the model and the model number for your laptop is PSLD4E.
    This model is specific for certain configuration of model and material. So when you choose this model number, you will get the list of all the important factors, tools and utilities for your laptop model.

    Generally speaking, all with tracks of updates simply and automatically. If you use the factory settings and the Toshiba recovery image it contains small tool called TEMPRO. This control of the tool if some updates are available and you will be informed if a new version is available.

    If you use clean install of the OS, you can download and install TEMPRO more.

If you want more details just drop free to write me [deleted]

    Gateway provides an XP driver for your laptop specific model? Go to the gateway support site to find out. I can't check for you because their site needs the serial number, not the model number. If this isn't the case, then XP is not supported on your computer. You need live without sound or put Vista on the machine. MS - MVP - Elephant Boy computers - don't panic!

  • After battery indicator Reset computer laptop cannot turn on

    Hi all

    I have serious problem reggarding this battery meter reset. I started on my Y580 and went to work. When I came back the cell phone was off and I couldn't. There are no indicators that the power addapter was pluged. When I press the power button, the red light blinks in front just 3 times and that's it. I can't start and it does not show that the battery is charging. It's as if the laptop does not detect the addapter AC or battery.

    The laptop is out of warrity!

    Help, please!

    Thanks in advance and best regards,

    There is a thread below with a person having a problem with his gun and did not want to do the reset for precisely this reason. I offered an alternative that might work.

    Well you can read now. I have no idea what would have been able to do. You can try pulling the Ac, battery, press the power button for at least 15 to 30 sec maybe he will discharge memory enough return lifel. Leave the battery for an hour anyway. Plug it into CA only and see if it turns on and runs. Then try to add the battery.

    Probably the CD was born before Windows 8 is why he knows nothing about this product "nice". Please visit the following site. Hope that your printer is still the list:
