Why can’t I see my WiFi network on my device?
There are several reasons why you may not be able to see your WiFi network on your device. One common reason is that your WiFi network may be set to “hidden” or “invisible” mode, which means that it will not broadcast its name (SSID) to nearby devices. This is often done for security reasons, but it can also cause issues if you’re trying to connect to the network. Another reason may be that your device is not in range of the WiFi network, or that there is interference from other devices or physical barriers.
To resolve this issue, try checking your WiFi router’s settings to see if the network is set to “hidden” mode. If it is, you can try changing the setting to make the network visible. You can also try moving your device closer to the WiFi router or restarting the router to see if that resolves the issue. If you’re still having trouble, you may want to try resetting your WiFi router to its factory settings or contacting your internet service provider for assistance.
How do I reset my WiFi router to its factory settings?
Resetting your WiFi router to its factory settings can often resolve connectivity issues, including not being able to see your WiFi network. To reset your router, you’ll typically need to press and hold a small button on the back or bottom of the device for a few seconds. This button is often labeled as the “reset” button, but it may also be a small pinhole that you need to press with a paper clip. Consult your router’s user manual or manufacturer’s website for specific instructions on how to reset your particular model.
Keep in mind that resetting your router will erase all of its custom settings, including your WiFi network name and password. You’ll need to set these up again after the reset is complete. It’s also a good idea to make a note of your current settings before resetting the router, so you can easily set them up again.
