When I attempted to connect to a wireless network, after changing a password for authenticating with systems in use at a location, when I arrived at that location today with my MacBook Pro laptop, I found that instead of connecting to the wireless network at that location automatically, I was not able to establish a connection to the WiFi network. When I checked the Network settings under System Preferences, I found that for the Wi-Fi connection it was showing "Self-Assigned IP" with the message "Wi-Fi has the self-assigned IP address 169.254.57.115 and will not be able to connect to the Internet. For that network, the laptop needs to authenticate with 802.1X to gain access to the network." But the status for 802.1X was stuck at "Authenticating." I was able to successfully authenticate after changing the "802.1X Password" for the wireless network through the Keychain Access utility.
