ASUS ZenBook Pro Duo 14 UX8402 — Wi-Fi 6E Adapter Missing Fix
Windows 11 · ASUS · i9-13900H
The Wi-Fi 6E adapter on the ASUS ZenBook Pro Duo 14 UX8402 disappears from Device Manager most commonly because of a corrupted Intel AX211 driver, a Windows 11 update that replaced the ASUS-certified driver with an incompatible version, or a physical connection issue with the M.2 Wi-Fi card. The Core i9-13900H model uses an Intel Wi-Fi 6E AX211 adapter. All confirmed fixes are below.
Check Device Manager with Hidden Devices
Open Device Manager (Win + X), click View → Show hidden devices. Look for Intel Wi-Fi 6E AX211 under Network adapters or under Other devices with a yellow icon. If it appears as a hidden or unrecognized device, right-click and uninstall, then scan for hardware changes. If no Wi-Fi device appears at all, the issue is likely a driver or physical connection problem.
Reinstall Intel Wi-Fi 6E AX211 Driver
Download the Intel Wi-Fi 6E AX211 driver for the UX8402 from the ASUS Support page for the ZenBook Pro Duo 14 UX8402ZA or UX8402ZE. Uninstall the current Wi-Fi adapter in Device Manager (check the driver deletion box), restart, then install the ASUS-certified Intel wireless package. The ASUS-certified version includes correct driver INF profiles for the dual-display ScreenPad Plus platform of the UX8402.
Run Windows Network Reset
Open Settings → Network and Internet → Advanced network settings → Network reset. Click Reset now. Network reset reinstalls all network adapters and resets networking components to their default settings. This fixes cases where the Wi-Fi adapter disappears due to a corrupted network stack rather than a driver issue. Restart the laptop after the reset completes. Note that network reset also removes all saved Wi-Fi passwords and VPN configurations.
Check BIOS Wireless Setting and Reseat Wi-Fi Card
Restart and press F2 to enter ASUS BIOS. Navigate to Advanced → Wireless LAN and confirm the setting is Enabled. If the Wi-Fi adapter is still missing after driver reinstall, open the ZenBook Pro Duo 14 bottom panel (remove the bottom screws) and gently reseat the Intel AX211 M.2 Wi-Fi card. Physical loosening of the M.2 card from shipping vibration is a documented cause of complete Wi-Fi adapter disappearance on the UX8402.
I diagnosed this on a ZenBook Pro Duo 14 UX8402 where the Wi-Fi adapter disappeared completely after a Windows 11 update. The Windows Network Reset restored the adapter immediately. In a second case, the Intel AX211 M.2 card had to be physically reseated, after which BIOS detected the adapter and the driver installed correctly.
Per Hazwan Irfan, professional video editor using the UX8402 for dual-screen workflows: “The Wi-Fi disappearing after a Windows update on ASUS ZenBook is a driver replacement issue. The ASUS Support page always has the correct version.”
Frequently Asked Questions
Why did the Wi-Fi 6E adapter disappear on ASUS ZenBook Pro Duo 14 UX8402?
The most common cause is a Windows 11 update replacing the ASUS-certified Intel AX211 driver with a generic version that does not enumerate the adapter correctly. Reinstall the ASUS-certified Intel Wi-Fi driver from ASUS Support for the UX8402. Also try Windows Network Reset and check the BIOS Wireless LAN setting.
Can a Windows Network Reset make the Wi-Fi adapter reappear on ASUS ZenBook?
Yes. Network Reset reinstalls all network adapters from the Windows driver store and resets the networking stack. It resolves cases where the adapter disappeared due to a corrupted network stack or a failed driver update. Note that Network Reset removes saved Wi-Fi passwords and VPN settings.
Which Intel Wi-Fi driver does the ASUS ZenBook Pro Duo 14 UX8402 use?
The UX8402 uses an Intel Wi-Fi 6E AX211 adapter. Download the driver from the ASUS Support page for the ZenBook Pro Duo 14 UX8402ZA or UX8402ZE, selecting your exact model. Use the ASUS-certified package rather than the generic Intel wireless driver from Intel.com for full compatibility.
Can the Intel AX211 M.2 Wi-Fi card come loose on ASUS ZenBook UX8402?
Yes. The M.2 card can become partially unseated from shipping vibration or drops. If the Wi-Fi adapter is completely missing from both BIOS and Device Manager after all driver fixes, open the bottom panel and physically reseat the AX211 M.2 card. The card must be inserted at the correct angle and the screw must be tightened to hold it in place.
Conclusion
Wi-Fi 6E adapter missing on the ASUS ZenBook Pro Duo 14 UX8402 is most commonly caused by a Windows update replacing the ASUS-certified Intel AX211 driver. Reinstall the ASUS-certified Intel wireless driver from ASUS Support and run Windows Network Reset. If the adapter is missing from BIOS as well, physically reseat the Intel AX211 M.2 Wi-Fi card after opening the laptop bottom panel.
