If it says insecure network- how do I make it secure?
How do I make an insecure network on wifi secure?
Question marked as
Is it your wifi network? You can only do something about it if it's your network.
If it's your network, then you'd need to figure out how to get into the wifi router settings and change the security settings. Might have to google the model of your router to find instructions
