Lenovo ThinkPad L470 Won't Connect to Wi-Fi

Ensure that the wireless switch or function key (often Fn + F8 or F9) is turned on. Open Windows Settings > Network & Internet > Wi-Fi and make sure the toggle is set to On. If using Airplane Mode, disable it to restore network connectivity.

Verify that other devices can connect to the Wi-Fi network. Restart your router or modem and wait 30 seconds before reconnecting. If only the ThinkPad is unable to connect, try forgetting the network and reconnecting by re-entering the password.

Ensure that Airplane mode is turned off. You can find this setting by clicking the network icon on the taskbar or by going to Settings > Network & Internet.

Windows includes a built-in tool that can automatically find and fix common network problems. Go to Settings > Network & Internet > Status. Then, select Network troubleshooter and follow the on-screen instructions.

Access Device Manager, expand Network adapters, and find your wireless adapter. If it has a down arrow, right-click and Enable device. If it has a yellow exclamation mark, right-click and select Update driver, then search automatically for drivers. If the adapter is missing, try showing hidden devices or manually reinstall the driver.

Download the latest wireless LAN driver for your L470 from the Lenovo Support website. In Device Manager, uninstall the current Wi-Fi adapter driver, including its software if prompted. Then, install the downloaded driver and restart your laptop.

In Settings > Network & Internet, find Advanced network settings, then Network reset. Click Reset now and confirm. Your PC will restart, and you'll need to reconnect to your Wi-Fi using your password.

Open Command Prompt as an administrator. Run the following commands: netsh winsock reset, netsh int ip reset, ipconfig /release, ipconfig /renew, and ipconfig /flushdns. Restart your computer.
