Run the Network Adapter troubleshooter Start here
Go to Settings → System → Troubleshoot → Other troubleshooters and run Network Adapter. Select the Wi-Fi adapter when prompted. The troubleshooter can reset the network stack and re-register the adapter with Windows, which resolves many post-update Network Adapter Not Found errors.
Reinstall the Intel Wi-Fi driver from HP Support
Go to HP Support, find ProBook 450 G11, and download the Intel Wi-Fi driver. In Device Manager, expand Network Adapters. If the Intel adapter is missing or shows a yellow warning icon, right-click and Uninstall it, then run the HP driver installer and restart.
Reset the network stack with netsh commands
Open Command Prompt as administrator and run these commands in order: netsh winsock reset, then netsh int ip reset, then ipconfig /release and ipconfig /flushdns. Restart after running all commands. This resolves network stack corruption that prevents Windows from finding the adapter.
Check BIOS for wireless adapter enable setting
Restart and press F10 to enter BIOS. Navigate to Advanced → Built-in Device Options and confirm the Wireless Network Interface Controller is set to Enabled. HP ProBook BIOS can disable the wireless adapter after a failed firmware update, making it invisible to Windows.
Disable adapter power management
In Device Manager, right-click the Intel Wi-Fi adapter → Properties → Power Management. Uncheck Allow the computer to turn off this device to save power. This prevents the network adapter from being turned off by Windows power management and failing to reinitialize correctly after resume from sleep.
Update the BIOS
Install the latest BIOS from HP Support. HP ProBook BIOS updates include fixes for PCIe enumeration issues that can prevent the M.2 Wi-Fi card from being detected correctly during boot, appearing as a missing network adapter in Windows.

Frequently Asked Questions
What Wi-Fi chip does the HP ProBook 450 G11 use?
The HP ProBook 450 G11 uses an Intel Wi-Fi 6E AX211 or AX203 adapter depending on configuration. The specific model is visible in Device Manager under Network Adapters once the driver is installed. Both use the same Intel Wi-Fi driver package available from HP Support.
Can I replace the Wi-Fi card in the HP ProBook 450 G11?
Yes. The ProBook 450 G11 uses a standard M.2 2230 slot for the Wi-Fi card. Any Intel or approved Wi-Fi 6 or 6E M.2 card can replace the existing one. Ensure the replacement card is on HP hardware compatibility list to avoid issues with Secure Boot or HP Sure Start.
Why does the network adapter disappear after sleep on the ProBook 450 G11?
Windows power management can fail to correctly re-enumerate the PCIe Wi-Fi adapter after resume from sleep. Disabling power management on the adapter (as in step 5 above) and updating both the Intel Wi-Fi driver and BIOS resolves most sleep-resume network disappearance issues.
Does the HP ProBook 450 G11 support Wi-Fi 6E?
Yes, configurations with the Intel AX211 adapter support Wi-Fi 6E (6 GHz band) in addition to standard Wi-Fi 6 (2.4 GHz and 5 GHz). The 6 GHz band requires a Wi-Fi 6E compatible router. Standard Wi-Fi 6 and earlier networks continue to work normally.
