Installation of Network Adapter driver

Anonymous

Hello everyone. I recently had some problem with my wifi as it regularly had ping spikes every 5-6 secopnd. I tried Network reset under Network and internet settings.

Afterwards my network adapter did not work.

It did not show up in Network connections. When checking Device manager, it shows up in "other devices" as "network controller". When checking device status, it says

"The drivers for this device are not installed. (Code 28)

The installation of this device is forbidden by system policy. Contact your system administrator."

Same message when trying to update the driver.

I have so far tried doing the network reset again and restarting computer.

I have also tried the following methods:

Disabling "Prohibit non-administrators from applying vendor signed updates" in group policy.

Selecting "all users except local administrator" in Software Restrictions Policies

And creating Disable MSI with value 0 in HKLM\Software\Policies\Microsoft\Windows\Installer.

I'm currently out of options. Anyone have some ides on how to fix the problem?

So, HKCU looks good. But you have quite a bit of settings in HKLM for policies. Did you configure these yourself via gpedit or by manually editing the registry? Normally, I would only expect to see this for a managed device that is part of a domain environment.

For example, under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions\DenyDeviceIDs you are blocking a few devices. Based on the device IDs, there are for Broadcom Wireless Network Adapters

And under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions you have set DenyDeviceIDs = 1, which would enforce these restrictions.

I recommend you delete the keys DeviceInstall key to clear these out.

I also see that there are some entries created for HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers... This would imply that you are using applocker. This is not part of the issue but does reinforce the idea that some type of domain or organizational policy has been applied to this computer.

    Hello Again, and thank you for your continued help!

    I uninstalled the device from device manager, and restarted the computer. still no fix..

    Then checked:

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions.      DenyUnspecified Did not exist.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Srp.        MSI Enforcement did not exist. Only "default".

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Srp        Found "installer", and deleted it.

    HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows        Installer Did not exist.

    Tried to update driver in device manager again, but to no avail.

    Tried restarting my computer again, and attempt to update again, but still forbidden by system policy

    In the Device Manager, right-click the network adapter > select Uninstall device > restart. If you still have the issue, check the existence of these keys in the registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\

    Restrictions\DenyUnspecified should be empty or not exist.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Srp\Gp\Msi

    EnforcementMode should = 0 or not exist

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer should be empty or not exist

    HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\Installer should be empty or not exist.

    Hello and thanks for answering me!

    I did as you said, and went to group policy and set all changes back to "Not Configured".

    I also went to HKLM and deleted "Disable MSI". This did not help though as I still could not update the drivers in device manager. Same message about installation forbidden.

    I then followed your instructions and want to asus.com and installed the LAN drivers to my motherboard. after running the setup program, and installing drivers and software, I got "install wizard completed" with a message to open device manager and view to properties of the network adapters to access new features.

    Device manager still showing same message though.. No wifi adapter in network adapters. still in other devices with the message that drivers not installed. Still forbidden permission to update drivers from there.

    Do you have any other tips that can help me?

    Hi and thanks for reaching out. My name is William. I'm a Microsoft Windows Certified Professional and Systems Administrator. I'll be happy to help you out today.

    If you are a member of the administrators group, then you have effectively disabled the ability for yourself to add drivers and unless you are on a domain with managed policies, there is no need to toggle these settings or have them enabled. Go back into gpedit and set those policy settings back to Not Configured and remove any manual registry entries you have made and restart the computer. Check to see if Windows may be able to apply the driver required if they are already staged.

    If no device driver is still present after restart, you will need to go to the computer/motherboard manufacture to obtain the LAN drivers for the device. If this is an aftermarket wired/wireless add-on device, then obtain the drivers from vendor's site.
