Guessing this laptop circa 2015. Haven't used it much in the past year.
There is no wireless adapter in device manager. This is listed under Network Adapters: Bluetooth device (personal), BT dev (protocol), Realtek PCIe GBE Family Controller and 8 WAN entries. Under Bluetooth it lists a Broadcom adapter. I don't know or care if that works.
I used the virtual advisor at HP.
They have both Broadcom (win10, I use 8.1) and a Realtek drivers. I downloaded the ReaItek. I did find the Broadcom for W 8.1 elsewhere. When I saved it, seems I already had that saved in 2015. None of these will install the adapter.
I'm not sure which adapter I should have. When I use HP Recovery, a Broadcom wireless adapter is listed to recover and that doesn't work either!
I remember years ago I had trouble with the wifi. I think I went to services to start 'something'. I checked there but nothing points to wireless
