ubuntu16.04, in the network configuration to find 802.1x security, enter the account password, why not connect? This is a bug in the system.
Solution: Suppose you have a certain Ubuntu foundation, first you set up good one can not use the protocol, is to follow the method established before the good, to remember its name, it will always prompt you to enter the password, but does not affect, turn off on the line, but must be established well. 1. Ctrl+alt+t Open Terminal
2. Cd/etc/networkmanager/system-connections
3. LS, you can see the previously created configuration file (as per the above steps, here should be able to find Ethernet), we need to modify this file
4. Because this directory is not under home, if you want to modify, you must have administrator rights: sudo vim Ethernet, and then enter the system password, enter into this file
5. The cursor jumps to the [802-1x] block, and you will notice that identity=xxx,xxx is the user name you entered when you configured the file, but this block does not have the password you entered when you configured the network, so, under the identity line, add a line: password =xxxxx,xxxxx, change your password.
6. Save, exit. 7. Shut down (shutdown now, do not reboot, may still not link), boot, and then you can connect the network.
