i performed the following task as answered by davidm. however, it would not let me save the setting. the button stayed grayed out:
I had the same problem, wireless network would ask for a password to authenticate, then connect and after a couple of seconds it would disconnect again. This process would repeat itself over and over. Even with entering the password directly at the wireless security tab as described here, it would still pop-up with the password dialog box & sometimes connect, but still keep on disconnecting.
This is what I did to solve the problem - it's a workaround, but hopefully later updates will fix this issue.
Establish a connection to your wireless connection Click on the network icon at the top right-hand of your screen Select 'Edit Connections' at the bottom Select the 'Wireless' tab Select your network & hit 'Edit' Select the 'IPv6 Settings' tab Where it says 'Method: Automatic' make it 'Ignore'
any assistance would be greatly appreciated.
