Wireless connection being dropped all the time

I have a Dell Latitude E6510 with a DW1520 Wireless-N WLAN half-mini card.  I used to have a D-Link router which broke down so I purchased a new router which is a Linksys E2500.  I changed the configuration on my laptop to use WPA instead of WEP.  My router is configured with fixed channels (not auto).  My internet connection is continuously being dropped and I have to re-logon to everything (very annoying with vpn tunnels).  All my other desktops/laptops in the house work without problems.

Hi dirk1,

Make sure the distance of the system and the router is not more than 30 ft.

To get the maximized the performance of 'Wireless Card' installed in the laptop:

  • Right-click the 'Computer' icon on the desktop or from the 'Start menu'
  • Click 'Manage'
  • Click 'Device Manager'
  • Click the + sign to expand the 'Network Adapters' entry
  • Right-click the wireless adapter and click 'Properties''
  • Click the 'Advanced' tab to configure the advanced settings
  • Select Power Management, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.

Note: If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance.

Check if the issue is fixed. If the issue still persists, you can try changing the properties of the network card in Device manager. Below are the steps:

  • Click on 'Start' and right click on 'Computer'.
  • Click on 'Manage' and click on 'Device Manager'.
  • Go to 'Network adapter' and right click on the wireless card driver and click on 'Properties'.
  • Click on 'Advanced' and select “Channel” and change it to '11' on the right side.
  • Select 'Roaming aggressiveness' and change is to 'Highest'.
  • Click on 'Apply' and then 'Ok'.
  • Check if the issue is fixed.

In case the issue is not resolved, uninstall and re install the wireless driver:

  • Click on 'Start' and right click on 'Computer'.
  • Click on 'Manage' and click on 'Device Manager'.
  • Expand 'Network' and right click on the wireless driver. (Check the name of the driver which will help you re installing the driver)
  • Click on 'uninstall'.
  • Once the driver is uninstalled, click on 'Start' and click on 'Control panel'.
  • Click on 'Programs and features' and look for the application of the wireless card.
  • Right click on it and click on 'uninstall'.
  • Restart the system.
  • Click on the link: http://dell.to/QQaRri
  • Click on 'Download Now' and select 'Single file download'.
  • Click on 'Continue'.
  • Click on 'Save' and save the driver on the desktop.
  • Right click on the driver from the desktop and click on 'Run as administrator'.
  • Install the driver following the on screen instructions.
  • Restart the system and check if the issue is fixed.

If the issue still persists, update the BIOS:

Please find the link for BIOS update: http://dell.to/YeNTxi

Note: The ac adapter should be connected and the battery should be at least 10% charged. Please disconnect all the external devices connected to the system before updating the BIOS. Please save all the unsaved data as your system will restart automatically while updating the BIOS.

  • Click on the above link.
  • Click on 'Download Now'.
  • Select "Single-file Download" and click on "Continue".
  • Click on "Run" and follow the on screen instructions.
