How do I fix no hardware installed on WiFi. On system report the WiFi is listed and shows versions of software

If it shows no hardware then you have a hardware issue

Take it in for repair

Thank you for your detailed comment. I have the same issue as OP. The hardware part is not shown in System Information -> Network -> WiFi

At first, both WiFi and Bluetooth stopped working. Then I replaced the WiFi cable, and since then Bluetooth works again, but WiFi still not. Then I replaced the Airport/WiFi card, but the issue still remains

Do you maybe know what could cause the issue ?

The strange thing is that Bluetooth works with the new cable, and both the new and old card. It only doesn’t work with the old cable. The WiFi however doesn’t work at all. As far as I know, the card and cable are responsible for both WiFi and Bluetooth
