WiFi connection is not available

I have an old laptop, a Sony VAIO Fit 14 (SVF14221CLW) which I wanted to install linux on, however the Wi-Fi network does not work for it, apart from that everything is going great, although I don't know if the integrated graphics it has is coming to serve I will be attentive to the comments and thanks in advance!

Hii @Baycord, welcome to the community.
Can you clarify if the wifi option is missing or you arent able to connect to any network?
And can you do sudo lshw -C network

If you are not dual booting with Windows, then You must disable Secure Boot in your BIOS Settings. Secure Boot blocks the Broadcom wifi driver.

If disabling secure boot does not resolve the issue, in terminal run?

sudo apt install --reinstall bcmwl-kernel-source
