Cannot connect to Wi-Fi: Wireless toggle is not displayed

I just bought a new laptop (Lenovo IdeaPad Slim 3, if it’s relevant), it had no OS and I decided to install Mint. The problem is that I cannot get Wifi to work.
When I click the network manager icon on the taskbar, it only shows "Network Settings" and "Network Connections" buttons, there is no Wireless toggle.

I don’t know what info you need so I will leave everything I can think of (or tried) here:

OS: Linux Mint 21.2 Cinnamon
Cinnamon version: 5.8.4
Linux Kernel: 5.15.0-767-generic
Processor: Intel Core i5 1335U
Graphics Card: Intel Corporation Device a7a1 

Output to lspci -nn | grep0280

00:14.3 Network Controller [0280]: Intel Corporation Device [8086:51f1] (rev 01)

Output to iwconfig:

lo no wireless extentions.

There are also some ACPI BIOS Error (bug): Failure creating named object ... these kinds of errors showing up when I turn on the laptop, but I read that it’s not really a problem (I might be wrong)

I also tried sudo apt update && sudo apt upgrade, but the output says that it cannot resolve and

Also tried sudo apt install bcmwl-kernel-source, same thing, could not be resolved.

Output to rfkill list

0: ideapad_wlan: Wireless LAN
             Soft blocked: no
             Hard blocked: no

(and then the same thing for “ideapad_bluetooth: Bluetooth” and “hci0: Bluetooth”

I don’t know much (anything) about drivers. When I open Driver Manager without the USB stick in, it tells me that I am offline. When I have the USB stick in, it asks me if I want to mount installation media, I press it and type the password and it searches for drivers and tells me that no drivers are needed.

At this point, i don’t really know what to try and I really want to try out this Linux thing, I will appreciate any help.

This problem was solved, here are the steps:

  1. Use USB tethering to get internet connection temporarily
  2. Install the latest 6.2 kernel with Update Manager
  3. Reboot and Wireless toggle should appear
