HP EliteBook WiFi Adapter Missing from Device Manager Windows 11: Fix

HP EliteBook WiFi adapter missing from Device Manager on Windows 11? The WiFi icon shows No network adapters found, the Network Adapters category in Device Manager is empty or does not list any wireless adapter, and the system cannot connect to any wireless network. HP EliteBook 840, 850, 830, 845, 855, and 865 models use Intel Wi-Fi 6 AX201, AX210, or AX211 adapters. After Windows 11 updates, these adapters can disappear from Device Manager entirely due to driver signing conflicts or power state issues that prevent the hardware from being enumerated on boot.

Why HP EliteBook WiFi Adapter Disappears from Device Manager

WiFi adapter disappearing from Device Manager on HP EliteBook is different from a simple driver failure — the hardware is not being detected:

• Intel WiFi adapter in deep power state (D3cold) — HP EliteBook BIOS power management can leave the Intel WiFi adapter in a power state where Windows cannot enumerate it; a BIOS update often fixes this
• HP Device Access Manager policy blocking WiFi — some HP EliteBook enterprise configurations use HP DAS to restrict wireless access; an IT policy may have disabled the adapter
• Driver signing conflict after Windows 11 Secure Boot update — on some EliteBook models, a Secure Boot database update can prevent an older Intel WiFi driver from loading
• BIOS WiFi adapter disabled — HP EliteBook BIOS has an explicit option to disable the WLAN adapter under Advanced Device Options

Check BIOS WiFi Setting First

Restart and press F10 at the HP logo to enter BIOS. Go to Advanced → Device Options or Security → Device Security. Look for Wireless LAN or WLAN and confirm it is set to Device available rather than Hidden or Disabled. On some HP EliteBook enterprise models, the WiFi adapter is administratively disabled here.

Fix HP EliteBook WiFi Adapter Missing on Windows 11

Step 1: Power Cycle with Battery Reset

Power off the EliteBook completely. Unplug the AC adapter. If the EliteBook has a removable battery, remove it for 30 seconds. For models with internal battery, press and hold the power button for 20 seconds after unplugging. Reconnect power and boot. This clears the D3cold deep power state and forces the Intel WiFi adapter to re-enumerate on boot. Check Device Manager after boot — the adapter often reappears after this procedure.

Step 2: Update BIOS and Intel WiFi Driver

Go to HP Support, enter your EliteBook serial number, and download the latest BIOS update and Intel Wireless LAN driver. Update BIOS first — HP EliteBook BIOS updates often contain fixes for Intel WiFi adapter power state management. After BIOS update, install the Intel wireless driver and restart. The adapter should now appear in Device Manager under Network Adapters.

Step 3: Run HP Hardware Diagnostics

Press F2 at boot to run HP PC Hardware Diagnostics. Run the Wireless LAN Test. If the test shows the adapter as not present, the issue may be hardware-level (loose M.2 card or failed adapter). On HP EliteBook business laptops, the Intel WiFi card is an M.2 A+E form factor module — a loose connection from shipping or transport can cause it to disappear from Device Manager.

Per Robert C., who is an IT Administrator managing HP EliteBook 840 G9 fleet: “After a Windows 11 24H2 rollout, about 15 percent of the EliteBook fleet lost WiFi from Device Manager. BIOS update from HP fixed the D3cold power state issue on all affected units. The fix was in the release notes: Intel Wireless adapter may not enumerate correctly after Windows 11 24H2 on certain power management configurations.”

Frequently Asked Questions

HP EliteBook WiFi adapter not in Device Manager — first thing to check?

Check BIOS at F10, Advanced, Device Options, and confirm WLAN is set to Device available. Then power cycle: shut down, unplug, hold power button 20 seconds, reconnect. Update BIOS from HP Support if the adapter returns but disappears again after restart.

HP EliteBook shows No network adapters in Device Manager — fix?

Go to View, Show hidden devices in Device Manager. If the Intel WiFi adapter appears as hidden or disabled, right-click and Enable. If completely absent, update HP EliteBook BIOS from HP Support — the BIOS fix for Intel WiFi D3cold enumeration failure is the most common permanent solution.

HP EliteBook WiFi was disabled by IT policy — how to re-enable?

HP Device Access Manager enterprise policies can disable the WiFi adapter at the OS level. Contact your IT administrator to check HP DAS policy settings. The adapter will not appear in Device Manager while blocked by HP DAS, even after BIOS changes or driver reinstalls.

HP EliteBook WiFi adapter appears in Device Manager but does not connect — different issue?

Yes. If the adapter is visible in Device Manager without an error but cannot connect, the issue is driver configuration or network settings, not hardware enumeration. Try the Intel Driver and Support Assistant to update the driver, and run netsh winsock reset in Command Prompt as Administrator.

Conclusion

HP EliteBook WiFi adapter missing from Device Manager on Windows 11 is fixed by checking BIOS WiFi settings, performing a power cycle with 20-second power drain, and updating BIOS from HP Support. The most common cause is the Intel WiFi adapter entering a deep power state (D3cold) from which it cannot recover without BIOS intervention. Hardware diagnostics at F2 can confirm whether the adapter is physically present or physically disconnected.
