- Turn Wi-Fi off and on again on your device.
- Restart your router/modem (wait 30 seconds before turning it back on).

Wi-Fi Symptoms and Causes?
Wi-Fi symptoms are the visible problems or issues you face while using a wireless internet connection.
Causes are the reasons behind those problems — the technical or physical issues that make Wi-Fi behave incorrectly.
| Wi-Fi connected but no internet | Internet provider is down / router issue |
| Wi-Fi is very slow | Too many devices / weak signal / interference |
| Wi-Fi disconnects often | Router overheating / signal drops / firmware bugs |
| Cannot connect to Wi-Fi | Wrong password / blocked device / IP conflict |
| Wi-Fi network not showing | Router off / wrong band / SSID hidden |
