Lubuntu does not find Wi-Fi (and I cannot connect to the internet by wire)

gb flag

I just installed Lubuntu 20.04 on an old Toshiba laptop (model is SATELLITE C40-C-10K) and it cannot find any Wi-Fi connection. It couldn't find a Wi-Fi connection also while I was on live boot, but I thought, it will find a connection when I install Lubuntu. I found several solutions on the internet, but they all require a wired connection. That's the problem, this laptop does not have a LAN port, therefore I cannot connect an internet cable to it.

Is there any way to connect to WiFi (assuming I still want Lubuntu on this laptop)?

I would also like to point out that I am a beginner when it comes to linux.

Thanks in advance

Edit: @chili555, I used the command lspci -nnk | grep 0280 -A3 and this is the output:

02:00.0 "0280" "14e4" "4365" -r01 "1b9a" "3002"
03:00.0 "ff00" "10ec" "5229" -r01 "1179" "f80b"

Let's start by identifying your exact wireless device. Please open a terminal Ctrl+Alt+t and run: `lspci -nnk | grep 0280 -A3` Next, edit your question to add the result. Welcome to Ask Ubuntu.

Not all WiFi hardware is supported by Linux out of the box. @chilli555 approach might help us to identify the right steps, once we know your hardware.

I believe that the result of the terminal command should be much more. Please double-check.

However, the abbreviated result you posted suggests that your wireless device is 14e4:4365, a Broadcom device. There are three options that you can use to install the driver.

First, and easiest, is to tether your phone to get a temporary internet connection. Open a terminal and do:

sudo apt update
sudo apt install bcmwl-kernel-source

The second option is that the driver and all its dependencies are present on the installation USB. Reinstall and be sure to select the option to install third-party software:

The third option is tedious but workable and is described here: Unable to use wifi card 16.04 MacOS dual boot

Well the result of the terminal is nothing more than these two lines, but I think it doesn't matter as the first solution you wrote worked perfectly. Thank you very much :D

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
