One of the most frustrating issues to encounter with any device is a WiFi connection problem. As a LIFE Tech Apprentice, I've encountered my fair share of WiFi issues with the Lenovo Ideapad Duet 3. Here are some common WiFi connection issues I've encountered and some troubleshooting steps you can take:

1. WiFi not connecting: If your Ideapad Duet 3 is not connecting to WiFi, the first step is to make sure your WiFi is turned on. You can do this by going to the "Settings" app and selecting "Network & internet". If WiFi is turned off, turn it on.
2. Weak signal: If your WiFi signal is weak, you can try moving closer to the router or switching to a different WiFi network with a stronger signal. You can also try resetting your router or modem to improve signal strength.
3. Intermittent connection: If your WiFi connection is intermittent, meaning it frequently drops or disconnects, you can try resetting your network settings by going to the "Settings" app, selecting "System", and then "Reset options". You can also try updating your network drivers.
4. Limited connectivity: If your WiFi connection shows as "Limited" or "No internet access", you can try restarting your router, resetting your network settings, or running the Windows Network Troubleshooter.

By following these troubleshooting steps, you can resolve many common WiFi connection issues on your Lenovo Ideapad Duet 3 and ensure a stable and reliable connection.
