Windows update (24H2) causing wifi issues

Anonymous

Hi,

I installed the new windows 11 24H2 update about a week and for whatever reason my wifi drivers have stopped working (specifically the Killer (R) Wi-Fi 6E AX1675i). The wifi option itself no longer appears.

I have tried a number of the solutions listed on this forum involving troubleshooting, a network reset, entering the netsh/ipconfig commands on CMD for TCP/IP reset, uninstalling and reinstalling the drivers, restarted the router (not the modem, but I don't think this should be an issue as other devices seem to connect just fine) and nothing seems to be working. I didn't realize that I hadn't approved system restore, so I don't have a restoration point I can restore to. Uninstalling the update doesn't seem to be doing anything either (I am fairly sure that I uninstalled the correct update, but I could be wrong).

I have an Acer Swift Go 14 device (i7-1355u). I am not super technically adept, so I am not sure the following will cause any issues with connecting or not, but I have the Cisco AnyConnect Adapter driver, a VPN driver (Tunnel Bear), the Bluetooth Personal Area Network driver, a Realtek USB driver, and a bunch of WAN Miniport drivers as part of my network drivers.

Currently, I can only connect to the internet via an Ethernet connection.

Any help would be appreciated.

    Some suggestions for you to check:

    1. Try to check if this involves W11 24H2, 22H2 or affects also Windows 10 devices. There are some changes related to 802.1x authentication included within W11 security hardening (ie. Certification Authority validation, or Credential Guard, to name a few)
    2. Clarify if the issue actually involves 802.1x or involves later DHCP. Event Viewer > Applications and Services Logs > Microsoft > Windows > Wired AutoConfig / WLAN AutoConfig > Operational Logs would have a sequence of coded Events that might help in understanding the stage during which WLAN processing is failing.
    3. If WLAN processing seems ok, test if DHCP scope where leases are assigned after Key Exchange is hosting any invalid Options. We had some confirmed cases where errors were due to some

    Hope this helps!

    Hi Liam,

    This reminded me that when i finally got my wifi back the performance was really bad, so i did have connection but it was slow. After doing a speed test found connection speeds were minimal. The fix for me for this was a router reboot and this brought the speeds back to normal.

    Hopefully that works. Good luck!

    Hello,

    Based on the screenshot, since you have already reinstalled the drivers, and re-enabling does not help, it is likely an issue in the hardware or firmware.

    Since it i a laptop, I recommend contacting Acer for further assistance if the computer is still in warranty, or your local repair shop for a hardware check if not.

    Thanks for your patience and understanding.

    Hello adiZG,

    Thanks for reaching out here in the Microsoft Answers Community.

    Based on the description, are you using a desktop or a laptop? If you are using a laptop, it could be caused by the Wi-Fi card being powered off. Based on the model, it seems that there is a "flight mode" shortcut. One of the F1~F12 keys should have an icon showing an airplane; please press that key, and see whether the Wi-Fi can be re-enabled. If not, try holding down the "Fn" key while pressing that key.

    If that also does not work, please right-click Start->Device manager, right-click the Wi-Fi device, and select "Properties". Provide a screenshot showing the error code.

    We look forward to your response.

    Best Regards,
