How to fix problem 0x15?

Because the Wi‑Fi option itself is missing, enable the wireless adapter and restart the WLAN AutoConfig service before troubleshooting the mobile hotspot; the available information does not establish what error 0x15 means.

1. Check the HP wireless control

1. Turn off Airplane mode using the keyboard key showing an airplane or wireless antenna. On some HP laptops, hold Fn while pressing that key.
2. Look for a wireless indicator light:
   • White/blue generally indicates wireless is enabled.
   • Orange/amber generally indicates it is disabled.
3. Open Settings → Network & Internet and check whether Wi‑Fi has returned.

Windows hides the Wi‑Fi control when the wireless adapter is unavailable or when the WLAN AutoConfig service is stopped.^1^

2. Enable and inspect the Wi‑Fi adapter

1. Press Windows+X → Device Manager.
2. Expand Network adapters.
3. Locate an adapter whose name includes Wireless, Wi‑Fi, WLAN, 802.11, Intel, Realtek, Broadcom, or MediaTek.
4. If it has a down-arrow icon, right-click it and select Enable device.
5. If it has a yellow warning icon, open Properties → General and note the complete Device status message and code.
6. If no wireless adapter appears, select View → Show hidden devices and check again.

Microsoft’s Windows 10 procedure specifically recommends enabling the device when the Wi‑Fi option is missing.^2^

3. Restart the Wi‑Fi service

1. Press Windows+R, enter services.msc, and press Enter.
2. Find WLAN AutoConfig.
3. Right-click it and select Restart.
4. If it is stopped, open Properties, set Startup type to Automatic, select Start, and then OK.
5. Reopen Settings → Network & Internet.

The WLAN AutoConfig service scans for wireless networks and manages Wi‑Fi connections; if it is stopped, Windows can hide the Wi‑Fi control.^1^

4. Repair the HP Wi‑Fi driver if the adapter is missing or has an error

Before uninstalling anything, use another device to download the wireless driver for the exact HP product/model number from HP’s support site and copy it to a USB drive.

Then:

1. In Device Manager → Network adapters, right-click the wireless adapter.
2. Select Uninstall device.
3. If offered, select Attempt to remove the driver for this device, then choose Uninstall.
4. Restart Windows.
5. If Windows does not restore the adapter, install the HP driver from the USB drive and restart again.

Microsoft recommends having the manufacturer’s driver available before removing the installed driver, particularly when the PC currently has no Internet connection.^2^

5. If Wi‑Fi returns but the phone hotspot is not listed

This is then a network-detection issue rather than a missing-control issue.

1. Verify that another device can see the phone’s hotspot.
2. In the phone’s hotspot settings, switch its band to 2.4 GHz or enable a compatibility setting, if available.
3. Keep the phone close to the laptop and refresh the network list.
4. Open Command Prompt as administrator and run:

netsh wlan show drivers
netsh wlan show interfaces
netsh wlan show networks mode=bssid
netsh wlan show wlanreport

The output shows whether Windows detects the adapter, which radio types it supports, and which networks and frequency bands it can see. The final command creates an HTML wireless report and displays its location.^1^

If the adapter still does not appear after installing the correct HP driver, provide the HP model number, the complete Device Manager status, and where 0x15 appears. That information is needed to distinguish a driver, service, BIOS/radio, or hardware problem.
