Final answer:
To tell if WiFi is working on an Android device, check for the WiFi symbol in the status bar, ensure the WiFi is enabled in the Quick Settings panel, and check the network status in the Settings app under "Network & internet" > "WiFi". If there's an exclamation mark next to the WiFi signal, you are connected to the router without internet access.
Step-by-step explanation:
To tell if WiFi is working on an Android device, follow these steps:
- Check the status bar at the top of your screen for the WiFi symbol. A strong signal should be indicated by the symbol's filled-in icon.
- Swipe down from the top of the screen to access the Quick Settings panel. Confirm that the WiFi icon is highlighted; if not, tap it to enable WiFi.
- Go into the Settings app, tap on Network & internet, then WiFi. If you are connected to a network, it will show as 'Connected' under the network's name.
- If the connection persists but there is no internet, the WiFi signal may appear with an exclamation mark. This typically means that the device is connected to the router but there is no internet access.
If you cannot connect to a WiFi network despite following the above steps, you may need to troubleshoot your device's network settings or contact your internet service provider.
