Why doesn't Wi-Fi work on Linux Mint?

Question

linux

Installed Linux Mint. I use it, everything is fine and fine, except for one thing: wifi does not work. In the network settings, only a wired connection and a proxy. Iwconfig issues

no wireless extensions

. I tried some of the methods described on other forums - it does not help, so I decided to ask a question.
Thank you in advance.
