    Hit the Windows Key and the R keys at the same time. Type

    systeminfo.txt

    REMOVE THE PRODUCT ID and post the rest of the information back here. (Preferred)

    or an ipconfig /all log and maybe it will reveal something.

  • arun_mechy,

     

    The DW1501 Wireless-N WLAN Half-Mini Card looks ok.

     

    Start, control panel, device manager, network, double click on the DW1501 Wireless-N WLAN Half-Mini Card. Click on power management and uncheck the box, allow Windows to turn off this device to save power.

     

    Click on the advanced tab. Look and see if this adapter has Antenna Diversity. Some adapter have this and some don't, not sure about this adapter. If the adapter has Antenna Diversity, try changing if from auto to aux.

     

    Also try reading...

  • Hi brownc5,

    Please share the system model. Did you try connecting to any other wireless network? I will recommend you to run the diagnostics on your system to chec the hardware functionality:

    • Restart your system and keep tapping 'F12' as soon as the Dell logo appears.
    • Highlight 'Diagnostics' using up/down arrow keys and press enter.

    Please let me know if you get an error code/message.

    Change the power management settings of the wireless card:

    1. Click on ‘Start’ and right click on ‘My Computer’ and click on ‘Manage’.
    2. Click on ‘Device Manager’.
    3. Click the + sign to expand the ‘Network Adapters’ entry.
    4. Right-click the wireless adapter and click ‘Properties’.
    5. Click on 'Power Management'.
    6. Uncheck 'Allow the computer to turn off this device to save power'.
    7. Click on 'Ok'.
    Also, change the power options for the wireless card:
    1. Click 'Start'.
    2. Click 'Control Panel'.
    3. Click 'System and Maintenance'.
    4. Click 'Power Options'.

    7. Click the + symbol in front of 'Wireless Adapter Settings' to expand the section.
    8. Click the + symbol in front of 'Power Savings Mode' to expand the section.
    9. Select 'Maximum Power Savings' for the 'On Battery' setting.
        10.  Click on 'Apply'.
    You can also change the wireless channel and change ‘Roaming aggressiveness’ to ‘Highest’:
    1. Click on ‘Start’ and right click on ‘My Computer’ and click on ‘Manage’.
    2. Click on ‘Device Manager’.
    3. Click the + sign to expand the ‘Network Adapters’ entry.

    5. Click the Advanced tab to configure the advanced settings.
    6. Click 'Roaming aggressiveness' and change is to 'Highest'.
    7. Also, click on 'Wireless Channel' and change the channel to ‘11’.

    I will recommend you to uninstall and re install wireless driver in case the issue is not resolved:

    1. Click on ‘Start’ and right click on ‘My Computer’ and click on ‘Manage’.
    2. Click on ‘Device Manager’.
    3. Click the + sign to expand the ‘Network Adapters’ entry.
    4. Right click the wireless adapter and click 'uninstall'.
    5. Once done, click on 'Start' and click on 'Control Panel'.
    6. Click on 'Programs and features'.
    7. Look for wireless card's software; right click on it and click on 'uninstall'.
    8. Restart the system and click on the link: http://dell.to/QjjZDA
    9. Enter the service tag and select the operating system.
    10. Go to 'Network' and select the wireless card driver depending on the wireless card your system has.
    11. Click on 'Download File' and select 'Single-file download'.
    12. Click on 'Continue'.
    13. Click on 'Save' and save the driver on the desktop.
    14. Right click on the driver from the desktop and click on 'Run as administrator'.
    15. Follow the on screen instructions to install the driver.
    16. Restart the system.

    If the issue still persists, update the BIOS:

    Note: Please save any unsaved data as your system will restart automatically after updating the BIOS. Disconnect all the external peripherals like printer, camera, scanner, external hard drive, flash drive etc. Also, the battery should be charged 10% or above.

    • Click on the link: http://dell.to/QjjZDA
    • Enter the service tag and select the operating system.
    • Go to 'BIOS' and select the latest BIOS version.
    • Click on 'Download Now'.
    • Select 'Single-file Download' and click on 'Continue'.
    • Click on 'Run' and follow the on screen instructions.

    Keep me posted. Please reply for any further questions.

    Thanks and Regards,
