Macbook won't keep password for WiFi

[markw10]

A friend of mine has a MacBook and for some reason it won't keep the WiFi password for her home network. Whenever she restarts the Mac or turns it on it will find the home network but it prompts her for a password. She is selecting to have this network remember. Any idea why it would be doing this? Thank you for your help.

I assume 1) she checked "Remember password" when connecting to the network AND 2) the WiFi network is set as Preferred Network in AirPort preferences AND 3) AirPort is set to connect to Preferred Networks.


Turn off AirPort.
Open Keychain Assistant, find the entry relevant to the network, open it, click "show password", Keychain Assistant will ask if to allow access to this entry once or permanently, click "Always allow", enter password.
Quit the Keychain Assistant.
Turn on AirPort. Should connect to the network automatically and be OK from now on.

You can also try deleting the entery for her Wifi in key chain and then reconnect again and make sure to check Remember Password.

Sometimes when you have been connected to different Wifis with the same Name but different passwords Mac Os gets confused.
