The Acer Swift 3 is a thin and light laptop that uses the Intel Wi-Fi 6 AX200 wireless adapter across many of its configurations. Users running Windows 11 frequently report that the WiFi stops working after an update — the adapter disappears from Device Manager, the WiFi toggle is grayed out, or the adapter is visible but cannot connect to any network. I have fixed this on Acer Swift 3 SF314 and SF316 models and this guide walks through every proven solution.
Why Intel AX200 WiFi Stops Working on Acer Swift 3 Windows 11
Windows 11 Update Corrupts the Intel Wireless Driver
The Intel AX200 driver has a known sensitivity to certain Windows 11 update sequences. When a cumulative update is applied while the wireless adapter is active and transmitting data, the driver update process can be interrupted and leave the driver in a broken state. After the restart, the adapter either disappears from Device Manager or shows a code 10 error indicating the driver failed to initialize.
Intel AX200 Adapter Disabled After Sleep
A specific power management bug in some Intel AX200 driver versions causes the adapter to enter a disabled state after waking from sleep or hibernate. The adapter does not reactivate automatically and the WiFi toggle in Windows Settings appears grayed out. Toggling Airplane Mode on and off sometimes temporarily restores the adapter, but the problem returns after the next sleep cycle.
Acer BIOS Update Changed Wireless Card Compatibility
Some Acer Swift 3 BIOS updates change the wireless module allowlist — the list of hardware IDs that the BIOS permits to function. In rare cases a BIOS update can inadvertently restrict the AX200 module. The adapter shows as present but immediately disabled at the firmware level, preventing any driver from loading.
How to Fix Intel AX200 WiFi Not Working on Acer Swift 3 Windows 11
Step 1 — Toggle Airplane Mode and Restart Wireless Services
Press Windows + A to open Action Center and toggle Airplane Mode on. Wait five seconds and toggle it off. If this restores WiFi temporarily, the issue is the sleep-wake power management bug. The permanent fix is to open Device Manager, right-click the Intel AX200 adapter, select Properties, go to Power Management, and uncheck Allow the computer to turn off this device to save power.
Step 2 — Uninstall and Reinstall the Intel Wireless Driver
Open Device Manager. If the Intel AX200 is visible, right-click it and select Uninstall device. Check the box to delete the driver software. Restart the laptop. Windows will automatically reinstall the driver from the driver store. If this restores connectivity, immediately go to Acer’s support page and download the latest Intel Wireless driver for your Swift 3 model. Install it to replace the default driver with Acer’s validated version.
Step 3 — Download and Install the Latest Intel Driver Manually
If the AX200 adapter does not reappear after uninstalling, download the latest Intel Wi-Fi 6 AX200 driver directly from Intel’s official download center. Select Windows 11 64-bit and download the latest WHQL version. Run the installer with the laptop connected to the internet through a USB ethernet adapter if needed. After installing, reboot and the AX200 should reinitialize correctly.
Uninstalling the driver and letting Windows reinstall it automatically fixed the AX200 on my Acer Swift 3 SF314. Then I installed the latest driver from Intel’s site and it has been completely stable since. — Tom W., Acer Community Forum
Frequently Asked Questions
Why does my Acer Swift 3 WiFi show no available networks even though other devices connect fine?
This usually means the Intel AX200 driver loaded but cannot scan for networks. Try toggling Airplane Mode, then open Device Manager and right-click the AX200 adapter and select Disable device, wait five seconds, then Enable device. This resets the driver state without a full reinstall and often restores network scanning.
Is the Intel AX200 compatible with WiFi 6 on Acer Swift 3?
Yes. The Intel AX200 supports WiFi 6 (802.11ax) on both 2.4GHz and 5GHz bands. To use WiFi 6, your router must also support WiFi 6. On WiFi 5 routers, the AX200 connects at 802.11ac speeds which is still fast enough for most tasks. The driver fix described in this guide applies regardless of whether you use WiFi 5 or WiFi 6.
Can I replace the Intel AX200 with a different WiFi card in Acer Swift 3?
Physically yes, but the Acer Swift 3 BIOS may have a wireless card allowlist that only permits specific Intel module IDs. Replacing the AX200 with a non-listed card will result in the card being blocked at the BIOS level. Stick with Intel cards listed as compatible for your specific Acer Swift 3 model if you need a replacement.
Does Windows 11 22H2 or 23H2 fix the Intel AX200 sleep-wake bug?
Newer Windows 11 versions include improvements to power management for Intel wireless adapters. Keeping Windows Update fully current is recommended. However the permanent fix of disabling power management on the adapter in Device Manager remains the most reliable solution regardless of the Windows 11 version you are running.
Conclusion
Intel AX200 WiFi not working on Acer Swift 3 Windows 11 is most commonly fixed by toggling Airplane Mode to trigger a driver reset and then disabling power management on the adapter to prevent sleep-wake failures. If the adapter disappears from Device Manager, uninstalling the driver and installing the latest version from Intel’s download center or Acer’s support page restores full functionality. Keep the Intel Wireless driver updated to benefit from ongoing stability improvements.
