Ouch. Your screenshot hurts my eyes. Just run the commands like this
sudo lspci >> ~/Desktop/output.txt
and upload the text file. Much easier to read and much smaller.
Your WiFi chip may need additional drivers for Linux (more or less automatic for Ubuntu once connected with another network interface). See
here and
here. The wired interface should normally work out of the box. If not it may be a little tricky.
Reading only partially the many replies (that also go a little off-topic) I would say running legacy Windows is not a good idea
for a connected computer. In addition to the security problems there is missing support for newer software
(browsers) which leads to loss of functionality. While it is possible
somehow, I agree on that with
@Foxi4 , it's not worth the effort when other OS offer more security, more functionality and less work.
If you have time and interest for this, try multiple Windows and Linux versions and see which works best for you. On newer Windows (at least wired) network should work out of the box and in general less additional drivers are needed. Now that you know you have BCM4312 WiFi you can download the Windows driver for it. Automatic driver download applications are somewhat dubious in my opinion.
The thing with energy efficiency and slowness…
I can’t agree on that. Laptops do not need
that much energy (they can run on batteries after all) and if a system is not on 24/7 but only when needed, this has not much impact comparing to producing a new computer. Judging if a computer is fast enough for an area of application is up to the owner. Throwing away a system that still has an area of application is
waste.
