When booting my Laptop today I noticed my bluetooth and wifi was not working. Both state in the settings that no adapter is found. I started searching for solutions but nothing worked so far, and I've got the impression that at least the wireless network controller should be found. When I do lspci |grep Network nothing gets displayed.
When only using lspci I can at least find my ethernet, USB, ... controllers, but nothing stating wireless, WLAN, or similar. I can neither install additional drivers over Software & Updates as none get displayed, even when mounting a fresh iso and trying to take the drivers from there.
Using sudo lshw -class network gets me:

My guess now is that the hardware somehow broke, it is an older laptop. Is there any way to fix this, is it something different? I would really appreciate any help.
Thanks
