When you find that your Dell laptop cannot connect to the Wi-Fi network, you can try deleting the saved networks and then reconnect from scratch. You can use the steps below to manage the Wi-Fi on your Dell laptop:
• Step 1: Open the Control Panel and click "Network and Sharing."
• Step 2: Select ‘Manage Wireless Networks’ and review the networks
• Step 3: Right-click the connections and press "Remove network."
• Step 4: Close the control panel and restart the Dell laptop.
