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.
