We are seeing issues from time to time with out newly deployed laptops that have ac 7260 wirless chipsets. We do 802.1x PEAP (username/password).
When these devices boot up from a cold boot everything is fine 100% of the time. The user logs in and they get their wireless connection, etc...
From time to time when they wake from sleep their device will refuse to connect to our wireless network. In the windows error logs we are seeing this:
Wireless security failed.
Network Adapter: Intel(R) Dual Band Wireless-AC 7260
Interface GUID: {fef6bf55-f566-435e-b7ed-9d423ad57b69}

Wireless network is blocked due to connection failure.
Network Adapter: Intel(R) Dual Band Wireless-AC 7260
Interface GUID: {fef6bf55-f566-435e-b7ed-9d423ad57b69}
Connection Mode: Automatic connection with a profile
Profile Name: UAsecure
SSID(s): UAsecure
BSS Type: Infrastructure
Failure Reason:802.1x indicated there is no authenticator, but the profile requires 802.1x.
Length of block timer (minutes): 10
But we are not seeing anything even hit our aruba logs when this is happening. We are running aruba os version: 6.3.1.9
Turning off and on the wireless adapter does not seem to help. Rebooting the machine is the only way to re-connect to the wifi network. We have updated drives on some test machines, but have not had any noticable improvement.
Any Ideas?
Thanks,
Dan
