Killer(R) Wi-Fi 6E AX1675i Wireless Network Adapter not working

[TonyJose]

Hi all,

I’m using an Acer Swift Go 14 OLED with a Killer(R) Wi-Fi 6E AX1675i 160MHz Wireless Network Adapter (211NGW).

After installing the Windows 24H2 update (not sure if it’s the direct cause), my Wi-Fi became unstable — sometimes it worked, sometimes it didn’t. Eventually, it stopped working altogether.

Device Manager status for the adapter:

• Windows has stopped this device because it has reported problems. (Code 43)

• This device cannot start. (Code 10)

• {Operation Failed} The requested operation was unsuccessful.

Troubleshooting done so far:

• Toggled the adapter enable/disable in Device Manager

• Uninstalled/reinstalled the driver multiple times

• Tried multiple driver versions from Intel’s website

Current status:

• Wi-Fi doesn’t work at all

• Bluetooth and Ethernet connections work fine

Has anyone encountered this issue or found a fix? Any help would be greatly appreciated.

Thanks!

I have exactly the same problem as you, I have the same chip and the same 2 errors, code 43 and code 10. Killer(R) Wi-Fi 6E AX1675i 160MHz Wireless Network Adapter (201NGW).

I have the same internet adapter in a Lenovo laptop and after the same Windows update the Wifi can not work when connecting to 5GHz channels. I can still connect though to 2.4 GHz ones and access the internet.

I've checked the router settings and my laptop is connected to the 5GHz network but Windows believes there is no internet.

Hello NashRodriguez and VS6,

Thank you for posting in Intel Communities.

I completely understand that you're experiencing issues with the same network adapter (Intel® Killer™ Wi-Fi 6E AX1675i) on your OEM devices. However, I kindly ask that you start a new thread for your situation. This will enable us to concentrate on your particular issue and offer more effective support.

Sincerely,

Hello TonyJose,

Thank you for posting in Intel Communities.

To better understand the root of the issue, I would like to gather more information about your system. Please confirm if this is the actual device you are using and provide the following key details:

1. Have you manually downloaded and installed the drivers from the Intel Download Center, or have you used the Intel Driver & Support Assistant to update the drivers?
2. What version of the driver is currently installed?
3. Have you attempted to install the latest drivers from your OEM support page?

Additionally, I would greatly appreciate it if you could share your system configuration so I can thoroughly review it and offer an accurate solution.  This could be possible by downloading the Intel® System Support Utility for Windows* software. When the download is complete, launch SSU.exe.

• Scan: Check the box Everything.
• Click Scan.
• Review: When finished scanning, click Next.
• Click Save. *Attach the SSU log file as you reply.

I look forward to your response.

Best regards,

JeanetteC.

I have installed different versions of the drivers from both the Intel Download Center and the Intel Driver & Support Assistant (IDSA) tool. The current installed version is 23.150.0.4.
The "OEM Support" page redirected me to the Acer support page, where I also installed the version 23.30 provided there.

I have attached the SSU output for reference.

Hello TonyJose,

Thank you for the information and the SSU output. It's great that you've tested various driver versions from Intel and Acer. I'll review the SSU logs and check internally to identify the best solution. I'll update you shortly on the next steps.

Best regards,

I'm also facing the same issue. I haven't been able to see my Wi-Fi option in my Windows 11 for the last 2 months. I have attached the SSU output for reference.
