I can't access my wifi

[alexwegner]

Hello, me and my daughter's computers and phones logged out of the wifi and when we type the password in it says that our network requires a WPA2 password and we have put in the right password several times but it doesn't work. We have checked the password through the keychain access on the computer.

Have your wifi devices been connected to this network before? 

If you go out of range of the router, your wifi drops out. When back in range, your device reconnects by itself, unless you tell your device to "forget" the connection.

Are you connecting to the proper network? There might be a similar network close by. Your network name and password is on your router.

What is the keychain?
