Solved: D-Link WiFi Adapter Keeps Disconnecting

If your D-Link Wi-Fi adapter keeps disconnecting, there can be a variety of reasons, ranging from driver issues to interference problems. Here’s a step-by-step approach to diagnose and resolve the issue:

  1. Check the Basics:
    • Ensure the adapter is securely plugged into the USB port.
    • Test the adapter on another computer to see if the issue persists.
  2. Update or Reinstall Drivers:
    • Outdated or corrupted drivers can cause connectivity issues.
      • Visit the D-Link official website and search for the latest drivers for your specific Wi-Fi adapter model.
      • Download and install the drivers.
    • Alternatively, in the Device Manager (on Windows):
      • Right-click on the D-Link Wi-Fi adapter under “Network adapters”.
      • Select “Uninstall device”.
      • Disconnect the adapter and restart your computer.
      • Reconnect the adapter. Windows should automatically detect and install the necessary drivers.
  3. Change Power Management Settings:
    • Windows can turn off certain devices to save power.
    • Go to Device Manager.
    • Expand “Network adapters” and right-click on the D-Link Wi-Fi adapter.
    • Select “Properties”.
    • Go to the “Power Management” tab.
    • Uncheck the option “Allow the computer to turn off this device to save power”.
    • Click “OK”.
  4. Change USB Port:
    • The USB port you’re using might be faulty or not providing sufficient power. Try connecting the adapter to a different USB port, preferably one directly on the computer (not through a hub).
  5. Check for Interference:
    • Other electronic devices, such as cordless phones, microwaves, or other Wi-Fi networks, can cause interference.
    • Move your computer closer to the router or change the Wi-Fi channel on the router to reduce interference.
  6. Adjust Adapter Settings:
    • Go to the Network and Sharing Center (on Windows).
    • Click on “Change adapter settings”.
    • Right-click on your D-Link adapter and select “Properties”.
    • Click on the “Configure” button.
    • Go to the “Advanced” tab.
    • Adjust settings such as “Roaming Sensitivity” or “Transmit Power” based on the options available. These settings can vary depending on the specific adapter model.
  7. Update Router Firmware:
    • An outdated router firmware might cause compatibility issues. Check your router manufacturer’s website for any updates and install them if available.
  8. Try Another Network:
    • Connect to a different Wi-Fi network to determine if the problem is specific to one network or the adapter itself.
  9. Check for Software Conflicts:
    • If you have multiple networking software or VPNs installed, they might interfere with the adapter’s connection. Consider disabling or uninstalling other networking software temporarily.
  10. Contact D-Link Support:
  • If you’ve tried all of the above and still face issues, it might be helpful to contact D-Link’s technical support. They might offer model-specific solutions or determine if the adapter itself is faulty.

Lastly, if your adapter is still under warranty and continues to face issues despite all troubleshooting efforts, you may consider getting a replacement.
