Lost my network adapter

    Lost my network adapter

    I have been having intermittent problems with wifi connectivity so decided to uninstall my network adapters (Realtek and Dell) and then reboot to see if it would solve the issue. Unfortunately I must have checked uninstall driver on the Dell adapter because after rebooting, the Dell adapter had disappeared.

    I would really appreciate some advice on how to get it back. I remember in the (good) old days of XP I would get a "found new hardware" message on a reboot, but no more.

    Thanks in advance.

    Dell Inspiron 3521 Win 8.1

    Go to Control Panel > Device Manager. You should see the device there (probably with yellow exclamation marks). Click on the device and have it look for device driver - if that doesn't work use the computer your posting with to go to Dell website and download the drivers, then tell Windows to use those drivers.

    If you don't see the devices in Devices Manager, post back. That's a different problem.

    Download the drivers you need from here: Product Support | Dell US on another computer. Put on a flash drive then install on this computer.

    Thanks CB. That particular device is no longer showing on Device Manager.

    Thanks ZT, could you give me a quick heads up on how to install off the flash drive to the problem pc.

    Start Device Manager and right click on your computer's name and there you go.
    Unless you have selected delete during uninstall, then rescan should install it back.

    Thanks TO, did that and nothing reappeared under network adapters. I did click delete driver when I uninstalled it. I think it was called
    Dell Wireless 1704 802.11b/g/n(2.4GHz) I am presuming this is hardware as it appears under Device Manager.

    Is Dell Wireless 1704 802.11b/g/n(2.4GHz) hardware or software?

    That's the driver you need. Download it and put on a Flash drive.

    Take the flash drive to the computer with the network problem and install it by inserting the flash drive then double clicking on the file you downloaded.

    That should take care of it.

    Thanks ZT, done exactly that already, no result. Weird thing is I can connect to any other WiFi except this one easily. Everyone else in my family can connect to this one easily. Confused.

    Please post a screen capture of Device Manager with the Network Adapter section expanded.

    Also do the following:

    Open a Elevated Command Prompt:

    XP, Vista or Windows 7:

    Click on the Start button and type cmd.
    DO NOT press Enter or click Go.
    Look at the upper part of the window and you will see cmd.exe.
    Right click on it and select Run as Administrator.

    Windows 8 or 8.1:

    Press WIN + X to open Start context menu.
    Select Command Prompt (Admin)​.

    Paste the following into the Command Prompt window, exactly as shown, including double quotes:

    cmd /c "ipconfig /all > postme.txt & ping >> postme.txt & reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | find /i "proxy" >> postme.txt & notepad postme.txt & del postme.txt"

    and press ENTER.

    A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close. Post results in a reply here.
