    Let’s try the following steps:

    • Click "Start"
    • Right-click ‘’Computer’’ and then click ‘’Properties’’
    • Click ‘’Device Manager’’ in the upper left corner(if prompted to continue by the User Account Control) click ‘’Continue’’
    • In the ‘’Device Manager’’ window, click the next to ‘‘Network Adapters’’
    • Double-click on the wireless card
    • Click the Advanced tab
    • In the Property box, click Roaming Aggressiveness and select option 2. Medium-Low from the drop-down menu
    • In the Property box, click Throughput Enhancement and click to select Enable: from the drop-down menu
    • In the Property: box, click lick Transmit Power and click to select option 5. Highest from the drop-down menu
    • Click OK
    • Restart the computer

    If the above steps do not work, then perform the following steps:

    Update the wireless drivers. First check the wireless card that’s installed on the computer from Device Manager

    • Click on Start
    • Right-click on Computer
    • Click on Properties
    • Click on ‘Device Manager’ on the left sidebar.
    • Expand ‘Network adaptors’
    • Check the name of the wireless card

    Then go to our support site and install the drivers:

    • Click on the http://dell.to/QjjZDA
    • Type the service tag of your computer, click on ‘Submit’
    • Click on ‘Network’ and download the driver as listed in device manager
    • Click on ‘Download File’
    • Check on the radio box ‘Single-file download’
    • Click on ‘Continue’
    • Click on ‘Save’
    • Choose the location as desktop, save the file on the desktop
    • Double click on the file; choose ‘Continue’
    • Click 'OK' on ‘Select the folder’ where you want to unzip the files (make a note of the folder location)
    • Click ‘Yes’
    • Click ‘Ok’, follow the on screen instructions and install the file
    • Restart the computer

    In case you do not get prompts on the screen for instructions, then

    • Browse to the folder where the files were unzipped and locate the setup file
    • Double click on the file; follow the onscreen instructions to complete the installation

    I would also recommend you to update BIOS. Here is the link http://dell.to/UwLlYT

    Note: Before updating BIOS please ensure that:
    *Battery is 10%> or >10% charged
    *Battery charger should be connected
    *No external devices (flash drives, printers, external hard drives) should be connected.
    *All other programs should be closed and documents saved

    Please reply if you have any questions.

    Thanks & Regards,
