Missing wi-fi

[KAUL6665]

I have the VPC F12Z1E laptop, and overnight the wi-fi disappeared.

It does not show up at all, as if there is no wi-fi in the computer (yes, it's turned on..). Bluetooth is working. Could it be a hardware failure?

Hi KAUL6665 and welcome.

If you look in Control Panel -> Device Manager -> Network Adapters -> Wireless Adapter is the WiFi device shown as present and working correctly?

If it is missing then it may well be a hardware or connection failure and the WiFi card may need replacing/reseating.

No, it does not show. I can try to reseat it, but if i need to replace it, how do I find out the correct adapter to buy?
