Inspiron 7586 Intel AC 9560 not working / Can not install latest driver

Well, if it's not working on an older driver or a newer driver chances are the card may have failed. These can be changed out fairly easily.

To get this information you need to log on to support, enter your model number and most importantly Enter your Service Tag Number. 

That will open all the hardware information on your Particular notebook, You should download and read your Service Manual there you will find out how to open your notebook look for the section on changing out your Wi/fi card,

Hi Clintlgm,

thanks for your fast reply. I already thought about a defect of the WiFi-Card, but my notebook is quiet new, so I first took software problems into account. Is it realistic, that the card is broken? I still have warranty, so I better send it in to dell for repair. Is there a way to test, if the WiFi-Card is currupt?

Greetings, Ivo

Hi!

We have received your query and have created a support ticket for the same. I will drop in a private note shortly.

so what was the solution? I have the same problem on DELL 7786 intel AC 9560.

Regards

Wi-Fi card doesn't become corrupt they either are not making a solid connection or they fail. Drivers can become corrupt. If you have exhausted all attempts to install drivers with no Joy I suggest your Remove your Wi-Fi Card and Reset it. this would be the first step in troubleshooting it. Fairly simple operation if you at least have access to the proper size screwdrivers. Much preferred to send your notebook off to Service Dept for a couple of weeks. and if you do need to change out the card you'll already know how its done. and replacement cards are about $20 on Amazon This is the one I replace my Wi-Fi card with when it failed when my notebook was a couple of months old.

@rrdbWith a Intel Wireless AC-9560 I would suggest, in addition to the Wi-Fi drivers, that you also check on the chipset drivers since that card uses onboard Chipset/Processor components to function..

I have been suffering the same problem for the last couple of weeks. I have downloaded this file, but when I try to install it, I receive an Intel Software Installer message saying "This installation is forbidden by system policy. Contact your system administrator"

I got the same error message when trying to install the driver. What was the solution to this error? 

Have had this issue for awhile now. Scoured the forums for weeks, have tried everything. Tried so many registry edits I've had to reset to factory settings basically everyday.  I think the Wifi card may just be faulty and I'm gonna go back to dell support and scream at them until they replace it for free (laptop is three months old)

Yea you can aggravate yourself with Dell support all you want. Or you can just change the dam thing out yourself! I replaced mine for about $20 and 20 minutes of my time. I replace mine back in early Nov 2019 and am very happy that I did this is far superior to the one Dell had in my notebook. Dell Support after 3 attempts with different tech's, in the end, they just wanted me to Reset or clean install my OS, I installed this Wi-Fi card and never looked back.

I have experienced the same problem in the last week and after many hours, including back and forth with Dell on both the hardware and software side, managed to resolve it.

Using the Device Manager in Win10 I uninstalled the Device from the driver tab, and very importantly checked the box to uninstall the driver. Once youve done this Win10 will pick up the network card again (you might need to scan for hardware in device manager) and pick up the last driver it has. I had to do this several times to uninstall multiple drivers that the system had accumulated over time which seems to be the core of the problem. In the end I got back to a generic Microsoft Driver from 2018.  At that point I then went to the intel site, use the tool that can be found at https://downloadcenter.intel.com/product/99446/Intel-Wireless-AC-9560  which will identify and then help you install the latest driver.

Suddenly, the WiFi stopped working on my dad's laptop.

I downloaded the driver on this thread, but when I went to do the install, I get this message "The installation is forbidden by the system policy.  Contact your system administrator"

This is a personal laptop, there is no system admin!!

Help, I need to get this fixed for him!

I am experiencing the exact same problem on a Dell Inspiron 7391. is a solution available?

Hello, I’m your Dell virtual assistant. I see you've opened a thread.

In order for me to review your system configuration, may I have the Service Tag / Express Service Code/ Order Number?
