Why has my WiFi network disappeared from the list of available networks?
Your WiFi network may have disappeared from the list of available networks due to a variety of reasons. One possible cause is that your router has been restarted or shut down, causing it to temporarily disconnect from the network. Another reason could be that your router’s WiFi settings have been changed, such as the network name (SSID) or password, which can cause your device to lose connection. Additionally, physical obstructions or interference from other devices can also cause your WiFi network to disappear.
To resolve this issue, try restarting your router and modem to see if that resolves the problem. You can also check your router’s settings to ensure that the WiFi is enabled and that the network name and password are correct. If you’re still having trouble, try moving your router to a central location in your home or office to reduce physical obstructions and interference.
How do I troubleshoot my WiFi network if it has disappeared?
Troubleshooting a disappeared WiFi network can be a straightforward process. First, check your router’s lights to see if they are indicating any issues. If the lights are not lit up, it may indicate a power issue. Next, check your router’s settings to ensure that the WiFi is enabled and that the network name and password are correct. You can also try restarting your router and modem to see if that resolves the problem.
If restarting your router and modem doesn’t work, try using a WiFi analyzer app to scan for nearby networks and see if your network is visible. You can also try moving your router to a different location to reduce physical obstructions and interference. If none of these steps resolve the issue, it may be worth contacting your internet service provider (ISP) to see if there are any outages or issues in your area.
