Failure phenomenon:
Windows security windows are often ejected when you connect to a wireless network, and you will need to resolve them after closing.
Reason analysis:
This problem appears in the WIN8, Win8.1 operating system, and most of the campus network users. This hint results from the 802.1X authentication turned on. The 802.1X protocol was designed to address the problem of access authentication for wireless LAN users, which helps enhance the security of 802.11 wireless networks and wired Ethernet networks by requiring a certificate or smart card for network access, which is typically used for workplace connections.
Solution:
1, in the Computer Management---services, to find Wired AutoConfig and WLAN AutoConfig two services to ensure that the open state;
2, in the Network and Sharing Center---Change the adapter settings---Ethernet, right key properties, under the Authentication option, cancel the "Enable IEEE 802.1X authentication" Before the tick, save the settings;
3. Reboot the machine and reconnect the network.
Note:
If you turn on the Ethernet properties, there is no "authentication" entry, which means that the Wired AutoConfig service is not started and needs to be started manually.
