Ubuntu13.0464-bit systems cannot use 802.1x EAP authentication for Internet access solution

Recently, I re-formatted the original Ubuntu12.10 and installed the ubuntu13.0464bit system. After the installation, I found that I could not connect to the network using 802.1x EAP authentication, when the password is correct, the prompt "incorrect user name or password" is displayed in the pop-up window. Google has found this bug for a long time: see here. After a hard job, I almost tried to reinstall 12.10. Later I thought about how 12.10 can be used for 802.1x authentication.

Recently, I re-formatted the original Ubuntu 12.10 system with ubuntu 13.04 64bit installed. After the installation, I found that I could not connect to the network using 802.1x EAP authentication, when the password is correct, the prompt "incorrect user name or password" is displayed in the pop-up window. Google has found this bug for a long time: see here. After a hard job, I almost tried to reinstall 12.10. Later I thought that the original 12.10 was able to access the Internet using 802.1x authentication normally. How could this problem be solved by 13.04, this must have been a problem with Network-Manager. Therefore, we uninstalled Network-Manager in 13.04 and re-downloaded an old version of Network-Manager to allow 802.1x to access the Internet. The procedure is as follows:

1. Uninstall Network-Manager in Ubuntu 13.04

Sudo apt-get remove network-manager

Sudo apt-get remove network-manager-gnome

2. Download the old version of Network-Manager. Here I have downloaded the version 0.9.4.

Download Network-Manager

Download the package, decompress the package, and use the command line terminal to enter the unzipping directory. Then you can install dpkg-I * and restart the system.

3. Do not update network-manager for future system updates
