When I boot the PC I noticed that it is not connected to the Internet on the Welcome screen. I log on and notice my apps that want to connect are not seeing the Internet. In Device Manager I see the AC 9560 driver disappear and come back several times. Then after about 1 min it stabilizes and I have a solid connection.
I have tried Network Reset from Windows settings
Intel Driver Scan Tool and updated the drivers
Deleted the hardware from device manager
I tried several methods to clear this issue.
This is on a new build and a fresh install of Windows 10
BIOS is up to date as well as all drivers
Per the Event Viewer:
Intel(R) Wireless-AC 9560 160MHz : Has determined that the network adapter is not functioning properly.
ACPI: ACPI BIOS is attempting to write to an illegal PCI Operation Region (0x4), Please contact your system vendor for technical assistance.
New Gigabyte Aorus Master motherboard.
That second error is an indication of a bug in the ACPI table in the BIOS. Did you replace another wireless adapter with this AC 9560? If so, it is an indication that the AC 9560 is not supported by your current BIOS. You should, if nothing else, check for updated BIOS release(s) and install the latest.
Also, note the following:
Hope this helps,
So I think I found the core of the issue. The AC 9560 has issue connecting to the Cisco Meraki MR33 access point. After much testing and a fresh install of windows I preformed the following:
Installed only the Intel WiFi driver (the one located at my motherboards manufactures website (Gigabyte in this case))
Opened Windows Event Viewer and saw the Intel(R) Wireless-AC 9560 160MHz : Has determined that the network adapter is not functioning properly listed many times and growing.
Changed access points, no errors.
Looked at logs for the MR33 and see pages of:
ect...over and over.
I am now looking at the MR33 more to see if there is a workaround, but the workaround found when searching this on the Internet is to setup the MR33 as an open network (not going to happen).
I am having this exact same problem and I do not know how to fix it. Last week I was able to connect to 5GHz wireless networks without a problem. After running Windows Update I was no longer able to connect to a 5GHz wireless network. I have no problem connecting with 2.4GHz networks.
Sometimes I am able to connect to a 5GHz network if I wait long enough, but it does not function correctly. I can see these in the event log:
An update... I have tested the connection using Ubuntu in a flash drive. It works perfectly! So, it seems to be a problem with the Windows driver. I have managed to make it work on WIndows after a fresh install (factory reset) by using the 18.104.22.168 version of the Intel driver without performing any action on Windows update.
