I've got a Mid-2010 17" MBP freshly upgraded to 10.7. I went to the coffee shop today to do a bit of work, but I was unable to connect to the wifi network. I had been there yesterday(though without my laptop) and the wifi password had been changed. I updated the password on my iPhone and iPad, and those devices have been connecting to the network with no problems.
Today when I went in with my Macbook, however, I was unable to establish a connection with the network. I thought it was a bit strange, since it never told me the password was wrong(keep in mind, the laptop still remembers the old wifi network password), it just grabbed a self assigned IP and complained that it couldn't connect to the internet.
This is what I did in effort to establish a connection, with no success:
- Removed the network in question from my saved wifi networks. Upon attempting to reconnect nothing changed, still gets a self assigned IP, never asks for a new password, no internet connection.
- Removed all entries for the network in question from the Keychain. After removing the keychain entry, any time I reconnect to the network, the keychain entry is re-added with the old, incorrect, password.
- Edited the password in the keychain entry to the new, correct, password. This resulted in the same behavior as my first attempt, nothing new.
- Removed entry from saved networks, deleted keychain entry, restarted mac. Exactly the same as before.
So after a good 20 minutes of attempting to connect to the network, I could never even get it to prompt me for a new password(the password it has stored is definitely different than the current, correct, password for the network). So I gave up and came home to attempt to figure it all out.
Any suggestions on how to get connected to this network with a new password? Have I done all the right things, and should now just go file a radar on this behavior?
