Hello

Try the SFC scan on the computer.

SFC/scannow is a very useful command that you can use in any version of Windows. When the SFC (System File Checker) command is used with the/scannow switch, the tool analyzes all the important files of Windows on your computer and replace if necessary.

Missing and the corruption of the operating system (like many DLLs) files are probably the main cause of the major problems of Windows. In view of this, plus the fact that the SFC/scannow is completely automatic and very easy to use, the tool should be usually one of your top not troubleshooting.

  • Re: Equium A200-15i: Wireless stops working, so wireless adpater visible

    My netwrok A200-15i wireless stopped working by itself during the download.

    Internet works via ethernet. Wireless physical switch is on, but the indicator does not turn on. No wireless adapter appears in the "network adapters" in the system (only the Ethernet card is visible).

    During the installation of the Atheros driver, receive a message that the hardware is not connected.

    Help, please.

    Looks like the wireless card is dead the light that lights up with the switch is wired and not software driven.
    Even if it's very weird for the light to malfunction so there maybe a small chance of the card somehow has detached itself internally.
    I'm not familiar with the A200 I know that some earlier Toshiba models allow you access to the wifi cards since they are optional.
    For less hassle, buy a USB dongle or cardbus, but check online first that some brands good markets suffer from range and a poor performance.

    Hello

    BCCode: 117 is generally a problem of display driver (video) If you need to update (check the system machine
    and the sites of the manufacturer of the device. You will need to remove and reinstall your video card a PC and not
    edge. Perhaps a replacement card is necessary.

    If necessary you can perform in SafeMode with network - repeatedly F8 tap that you start.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system. For
    each driver in the list, additional useful information is displayed: load address of the driver, description,.
    version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
    video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
    cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
    own the software and drivers and all other main drivers that you have.

    Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
    (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
    updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

    Always check in the Device Manager - tab drivers version you install actually shows up. This
    because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
    pilot - reboot - check that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    If you update the drivers manually, then it's a good idea to disable the facilities of driver in the Windows updates,
    This leaves ONE of Windows updates, but it will not install the drivers who are generally older and cause

  • Wireless stopped working completely on WAG200G

    Radio has stopped working completely on my WAG200G. I'm not talking only a weak signal. My phone or my laptop can see nothing even when there is only 1 m. Works always wired network and the wireless router lights, but they don't blink at all.

    I tried a factory reset, but that did not work. Can it be fixed, or is it a hardware problem?

    Hi halfbeing,

    When you searched a wireless network using your wireless devices, see Linksys? When you did a factory reset, the number of seconds you pressed the reset button? Light should be blinking.

  • XPS13 9350 Wireless stopped working suddenly

    I have had the machine for about 30 days, and it worked fine.  All of a sudden today, the radio stopped working.  I'm on Windows 10.  In Device Manager, the Broadcom 802.11 card is a failure with the error message "this device does not and is being reset. (Code 54) ».  The driver version is 1.555.0.0.

    Please advise on how to diagnose the problem yet, and/or repair.

    Hello

    I had the same thing happen to someone using a Dell XPS 13 9350.

    I went into the BIOS settings and disabled the Bluetooth of the reworked wifi and wireless device. Of course if you need your laptop to be Bluetooth compatible, this solution is not ideal, but in the meantime, it's better than nothing.

    I hope this helps.

  • attachments cause Internet Explore stops working

    We have two email accounts a Hotmail.com and a single live.com.      Several months ago, perhaps when OUTLOOK can be downloaded on the stage is no longer able to send an attachment.   A short document or a photo causes the error "Internet Explorer has stopped working".   This is the only problem we seem to have.  Any suggestions?

    This happens when you click on the attachment button, or when you drag-and - drop a file in the email (or both?)

    I think that what I would like to try if it was me is first to open Internet Options, go to the Advanced tab and click the reset... button at the bottom.
