Hello,

after the installation of the 02/2015 and 03/2015 Windows Updates on our Windows 8 Notebooks (HP Folio 9470m) they cannot connect to the WLAN (802.1x) after the Computer wake up from sleep.

The computer always asks for user name and password even though it was correctly.

A computerrebootfixes the problem

 

Here the Error log:

Hi,

Generally speaking, this problem was caused by Wlan adapter goes into sleep. Therefore, firstly, please check WLAN driver settings in Device Manager, make sure the option "Allow the computer to turn off this device to save power" was unchecked.

Secondly, check Advanced Power Settings in Control Panel if there is some settings wrong.

On the other hand, you can also try to reinstall NIC driver for test.
