Hi @LAPTOP-C9PSRFIJ,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

Sorry for the inconvenience caused don’t worry let me help you.

To better understand the issue, could you please provide a few more details?

• Which HP laptop model are you using?
• Which Windows version (Windows 10 or 11) and build?
• When the Wi-Fi disappears, does it:
  • Vanish from Device Manager entirely?
  • Show with a yellow warning symbol?
  • Appear only after a restart?
• Do you see any error messages or codes?
• Has the laptop experienced any drops, overheating, or liquid exposure?
• Does the issue happen after sleep, shutdown, or randomly?

Meanwhile, here are some proven troubleshooting steps you can try:

Basic Checks

1. Restart Network Services
   • Press Windows + R, type services.msc
   • Restart:
     • WLAN AutoConfig
     • Network Connections
2. Check Device Manager
   • Go to Device Manager > Network adapters
   • Click View > Show hidden devices
   • If Wi-Fi appears:
     • Right-click → Uninstall device
     • Check Delete the driver software, then restart
3. Reinstall the Wi-Fi Driver from HP
   • Download the official Wi-Fi driver for your exact model from HP’s support page
   • Avoid using generic drivers from Windows Update
   • Install and restart

Power & BIOS-Related Fixes (Very Common Cause)

1. Disable Power Saving for Wi-Fi
   • Device Manager → Wi-Fi adapter → Properties > Power Management
   • Uncheck Allow the computer to turn off this device
2. Update BIOS
   • A BIOS update often fixes Wi-Fi disappearing issues caused by firmware bugs
   • Install only from HP’s official site
3. Reset BIOS Settings
   • Enter BIOS (usually F10 at startup)
   • Load Default Settings
   • Ensure Wireless / WLAN is enabled

Advanced but Important Checks

1. Full Network Reset
   • Settings → Network & Internet → Advanced network settings → Network reset
   • Restart the laptop
2. Check for Hardware Failure
   • If Wi-Fi frequently disappears from Device Manager
   • HP diagnostics (press F2 at startup) can help confirm this

I hope this helps.
