Dell XPS 13 7390 Laptop Will Not Connect To Wifi

The laptop may not connect if the Wi-Fi adapter is disabled in Windows or via a physical switch, so confirming it’s turned on is the first step.

• Check the taskbar for the Airplane Mode icon.
• If it’s enabled, turn it off.
• Open Settings → Network & Internet → Airplane mode to toggle it.
• Ensure Wi-Fi is switched On under the same settings menu.

Temporary network or software glitches can prevent connection. Restarting your Dell XPS 13 7390 and router can resolve these issues.

• Power off your Dell XPS 13 7390.
• Unplug your router and modem for 30 seconds.
• Plug them back in, wait for all lights to stabilize, then turn on your Dell XPS 13 7390 and reconnect to Wi-Fi.

Saved network profiles can become corrupted or outdated, so removing and re-adding the network can refresh the connection settings.

• Go to Settings → Network & Internet → Wi-Fi → Manage known networks.
• Select your Wi-Fi network and click Forget.
• Reconnect by selecting your network again and entering your Wi-Fi password.

Outdated or corrupted drivers can block the Wi-Fi adapter from working properly, so updating or reinstalling drivers can restore connectivity.

• Open Device Manager → Network adapters.
  Right-click your Wi-Fi adapter (e.g., Intel Wireless-AC or Killer adapter) and select Update driver.
• If that doesn’t work, select Uninstall device, reboot, and let Windows reinstall it automatically.
• You can also download the latest driver from Dell’s Support page.

Windows’ built-in tools can detect and fix software or adapter problems that are preventing the laptop from connecting.

• Open Settings → Network & Internet → Status.
• Click Network Troubleshooter and follow the on-screen prompts to automatically detect issues.
• If the problem persists, open Control Panel → Network and Sharing Center → Troubleshoot problems.
• Run Internet Connections and Network Adapter troubleshooters to identify software or driver errors.
• Restart your laptop once the diagnostics complete and test the Wi-Fi connection again.

If your Dell XPS 13 7390 still refuses to connect after software fixes, the internal Wi-Fi card might be the culprit. Over time, it can become damaged or fail.

• Open the back cover (see Dell’s official service manual).
  Ensure the Wi-Fi card is firmly seated in its slot.
• If it still doesn’t work, consider replacing the Wi-Fi card.
