— short context: the laptop’s Wi‑fi radio shows as off/airplane-mode after an OS install and built‑in fixes in the thread didn’t restore it. raised the possibility of a dead card; recommended the Windows troubleshooters. The quickest way forward is a small, ordered diagnostic flow that separates hardware from software causes.

Check whether Windows still sees the wireless adapter. Open Device Manager, enable “View → Show hidden devices,” and look under Network adapters and Unknown devices. If an adapter is present, open Properties → Details → Hardware Ids and note the VEN/DEV strings for a targeted driver search. From an elevated command prompt run:

netsh wlan show drivers

and

sc query wlansvc

to confirm a driver is bound and the WLAN AutoConfig service is running.

If the adapter is missing or shows error codes, test at the OS boundary by booting a Linux live USB (Ubuntu/Mint) and checking for Wi‑fi there. Wireless that fails in both Windows and Linux points strongly to a hardware issue; working in Linux but not in Windows points to drivers/configuration.

Other checks before opening the case: look for a hardware wireless switch or an Fn key radio toggle, verify the adapter is enabled in BIOS/UEFI (do not change unrelated BIOS settings), and in Device Manager turn off any “allow the computer to turn off this device to save power” power‑saving option. If Windows tools fail, use “Network reset” from Settings → Network & Internet as a last in‑OS step (it reinstalls adapters).

If hardware is suspected, a USB Wi‑fi dongle is an easy temporary workaround while deciding whether to reseat or replace the internal card. Take standard ESD precautions and back up data before any disassembly or BIOS changes.

Small world. We had two of those models at the insurance office and one of them the WiFi module failed. So at this point it's either:

  1. Drivers. I doubt this model has Windows 11 drivers so try the last driver HP offered.
  2. The WiFi card is dead or unsupported. For the office we replaced the card but for a quick fix we plugged in a USB WiFi adapter so the employee could finish their day and we fixed it later that day with a new card.

To access more troubleshooters, select Start > Settings > System > Troubleshoot. Choose Network Adapter > Run under Other. Check to see whether the issue is resolved by following the troubleshooter's instructions.
