my WiFi says authenticity problems

[Erika Fill]

I was able to connect my cellphone to my WiFi and now I can't. It now says authenticity problems. I can't figure out how to fix it

Did you change your wifi settings in your router? That would be the kind of thing to cause this. If all devices can not connect, it may be an idea to power cycle your modem/router/access point/ect

You should be able to remove the network from the phone and then re add it with the new settings.
