As we understand your Intel® Dual Band Wireless-AC 8260 stops working periodically and does not show any wireless network available. Here are some recommendations that may help in this case:
- Update the BIOS of your computer's motherboard.
- Install the latest version of Intel® PROSet/Wireless Software (19.1.0).
- Apply the configuration from the advisory: Recommended Settings for 802.11n Connectivity
For further assistance, please let us know the following:
- Was the adapter built-in from factory by the computer manufacturer?
- Does it happen when the PC performs a specific task? (resuming from sleep, running an app, etc.)
--Configuration settings are already correct
--When I install the latest version of the Intel PROSet Wireless Software, I get nothing. The Intel 8260 no longer appears as a device in device manager. Have to use a restore point to get back to the previous (semi) working driver.
--Adapter was installed by Puget Systems when they built the custom computer for me
--Problem doesn't happen under any specific circumstance, just intermittent
--Update for BIOS is available (7/26/16, 1901) - not installed yet, current installed BIOS is 1801 (5/12/16) for ASUS Z170-A motherboard
Please proceed with the BIOS update and let us know if there is a change in the behavior.
Also, we would like to have more information about the system configuration, since the documentation we found for the Asus* Z170-A does not mention any built-in wireless adapter, and the Intel® Dual Band Wireless-AC 8260 does not come in Add-in-card form factor, please clarify how the adapter was integrated to your system so we can get a better understanding of the setup.
Very interesting post, i also had troubles with an 8260 card since the day i bought it !!!
When i upgraded my acer VN7-571 with an SSD , during the removal of the wi-fi card, the antenna connector came apart, so i had to replace the original card (An atheros i think, don't know exactly.
I chose an intel 8260NGW for it's superior performance, however it never worked correctly.
In detail after a suspend, wake up and reboot, but also in other conditions the Wifi adapter or sometimes the bluetooh adapter, stops working with a code 10 error. The only way to bring it to work is to disable and then re-enable the device, or a complete shutdown. But sometimes also those trick did not work.
After some months of trials i decided to replace my notebook ( not only for the wi-fi issues ), now i own a lenovo y700. This lenovo came with a Qualcomm network card and i decided to install my 8260, i checked on the manufacturer website and is compatible with the 8260.
Still troubles, very similar to what i had with my acer, sometimes i get limited connectivity randomly or Bluetooth not working an so on.
I am running Win10 x64 PRO, bios is updated , tried with stock win 10 driver and the latest generic available from intel ... still issues.
Please help me find a way out from this nightmare !!!
Is there a possibility that my 8260 is a fake clone ?? can i figure it out just from the serial number ??
We would like to inform that a new Wireless driver has been uploaded to the Downloads for Intel® Dual Band Wireless-AC 8260. We recommend to make sure you are using the updated WiFi and Bluetooth* drivers.
Intel® PROSet/Wireless Software and Drivers for Windows® 10 [19.2.0]
Intel® PROSet/Wireless Software for Bluetooth® technology for Windows® 10 [19.00.1621]
Also, we advise to verify the Recommended settings mentioned in the previous post.
For errors related to power state changes (sleep, resume, shut down, etc.) you may try the following:
- Go to Device Manager, under network adapters, look for the AC 8260 Wireless Adapter and open the properties. Go to the "Power Management" tab and toggle Off/On the option "Allow the computer to turn off this devices to save power". Then check if the behavior changes.
- Disable Fast Startup (Hybrid Boot) in Windows® 10.
Tried all the suggested steps, (but alredy tried witm my acer ) with no luck !!!
I seriously don't know what to do .... could it be definitely an hardware issue ?? How can i figure out if my card is faulty or is it only a driver/software issue ??
I am seriously considering to discard this network adapter.... it is a really frustrating issue.
In this case, we advise you to check with the Computer Manufacturer Support, they will be able to confirm if your PC fully supports the Intel® Dual Band Wireless-AC 8260, or if there is anything else required to make it work in this configuration.
Please be aware that Intel does not support nor recommends custom installation of wireless adapters. They can only be installed by the manufacturer or its authorized representative. There may be compatibility issues or other problems after an unsupported upgrade.
I am having the same problem. I have tried to restart the computer with part of the services disabled, then the other part but nothing.
The only way I see to get it to work is to uninstall the BT and Net adaptor and then reboot.
Sometimes, not even that.
I do not understand how Intel asks us to go to the manufacturer. I started with a laptop that had a simple N card, no BT. I wanted BT and AC support so I opted to buy an Intel card.
Was working perfectly until the anniversary update. Since then, only trouble.
We understand your concern and would like to remind you that Intel does not recommend end users install or upgrade the various Intel® Wireless Adapter. There may be compatibility problems, regulatory issues, or even legal implications. Please review the following documents for more information:

We always provide our best effort under these circumstances, and we advise to apply the recommendations mentioned in this thread and other similar discussions. These include: clean installation of the OEM driver or Intel generic version, BIOS update, recommended configuration, power management options, etc.
If the issue persists at this point, we advise to check with the Computer Manufacturer Support for assistance.
