Random issues with Intel Wireless N 7260 Network card

Configuration:

Active Directory
Radius Server
Wireless Access Point
DHCP / DNS
Windows 7 Enterprise Clients

WLAN authentication with Computer account in Active Directory.

everything works pretty nice πŸ˜‰

Very strange problem. We have about 20 identical Notebooks (Make/Model), all use Intel Wireless N 7260 Network cards and are all in the same location.

Maybe we wouldn’t recognize the problem if they aren’t in the same room/location.

The Problem occurs after the System startup and User logon:
Logon Script / GPO not processed
connected to the Access Point / IP Address assigned but no ping on the Gateway possible
self-assigned IP Address 169.xyz.

All this errors are randomly on the Notebooks. The tricky part is, it’s only on 3 systems at the same time 😐

To reproduce or locate the error we tried different thinks. Start the systems in pairs, All Systems at the same time, …
Scan the Wi-Fi network with AirPcap/Wireshark, view logs from the Wireless Access Point. (it only shows successful connections / handshakes with the Radius Server) all works fine 😐

GPO adaptations: Always wait for the network at computer startup and logon…
Powershell Script: “Disable turn off this device to save power for NIC Power Management” (Links)
newest network driver from intel, …

problem has not changed.

finally, we found a solution. Delete the existing driver and install the last suitable driver from Microsoft update catalog. All Problems are gone. Now we use an older driver Version 16.10.0.5 (28.01.2014)

maybe it’s our setup configuration or a correlations of used systems

* slightly adapted. no reboot after every interface change

Windows 10 – default enabled UNC path hardening – Wifi

Issue: Logon Script is not processed within Windows 10 Enterprise x64 Machine on Wifi.

It seems to be an aftereffect the main Problem is found in the Windows Event Viewer – Windows Eventlogs – System


The processing of Group Policy failed. Windows attempted to read the file \\<corp.domain.com>\SysVol\<corp.domain.com\Policies>\{<PolicyGUID>}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following:
a) Name Resolution/Network Connectivity to the current domain controller.
b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller).
c) The Distributed File System (DFS) client has been disabled.

 

Error Code 65: Network access is denied.

After the Error Event 1058 appears it seems to skip the Logon Script too / it get Access Denied on the network share.

Workaround GPO:
Policy: Hardened unc paths
Category Path: Computer Configuration\Administrative Templates\Network\Network Provider\

Workaround Registry:
