Removed all entries for the network in question from the Keychain.Upon attempting to reconnect nothing changed, still gets a self assigned IP, never asks for a new password, no internet connection. Removed the network in question from my saved wifi networks.This is what I did in effort to establish a connection, with no success:


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. Today when I went in with my Macbook, however, I was unable to establish a connection with the network. I updated the password on my iPhone and iPad, and those devices have been connecting to the network with no problems. I had been there yesterday(though without my laptop) and the wifi password had been changed. I went to the coffee shop today to do a bit of work, but I was unable to connect to the wifi network. I've got a Mid-2010 17" MBP freshly upgraded to 10.7.
