Hi

Dunno.

I usually use the GETMAC command to list the MAC addresses.

Can you please post the results of yours?

Physical Address    Transport Name                                            
=================== ==========================================================
48-E2-44-54-66-27   \Device\Tcpip
B0-5A-DA-DE-84-28   Media disconnected                                        
48-E2-44-54-66-28   Media disconnected                                        

The above shows 3 mac addresses, the 48 E2 44 pair are for the WiFi and Bluetooth.

So if you have them, next would be install drivers to suit.

So the 38 14 28 comes back as Dell.

F0 77 C3 is assigned to Intel.

Do you have an ethernet port?

The hardware not present could indicate a failed piece of hardware.

So can you list the Wi-Fi card that you have?

Drivers are here...
