Good afternoon, I had a problem almost as soon as I downloaded Ubuntu. The first thing I tried to do was connect to Wi-fi, but I couldn't find an interface for that so I searched the internet for a solution. There I was suggested to install drivers for that, after knowing the manufacturer of my network card, but when I entered "sudo lspci | grep Network" I got absolutely nothing. Not a message that this command doesn't exist, not a message that I don't have a network card, it just throws me to a new terminal line and nothing else. What could be the problem and how can I fix it? All I get after using lspci :

    Are you sure it actually has WiFi? Try lspci only and find the line identifying the WiFi chipset. If it's an USB dongle then obviously use lsusb instead. – ChanganAuto Sep 25 '22 at 03:21
  • I have not found anything related to Wi-fi, but when the laptop was on Windows, I could connect to it, but after switching to Ubuntu this possibility disappeared and I can not find a solution to this problem. – mIbI Sep 25 '22 at 03:40
  • We're expecting your [edit] to the question with the info gathered from the lspci command then. – ChanganAuto Sep 25 '22 at 03:46
  • Added, hope this helps in some way – mIbI Sep 25 '22 at 03:54
  • A must read https://askubuntu.com/help/how-to-ask What is the version of Ubuntu you are using? – David Sep 25 '22 at 05:07
  • My version is 22.04.1 – mIbI Sep 25 '22 at 05:10

    Can you attach the output of lsusb too? – ArrayBolt3 Sep 25 '22 at 06:52
  • Yes, of course. Already added. – mIbI Sep 25 '22 at 07:15
  • There it is. Your WiFi card is attached via USB for some reason. "Bus 001 Device 004: ID 0bda:d723 Realtek Semiconductor Corp. 802.11n WLAN Adapter". If that's an actual USB WiFi dongle, can you share its model number with us? If not, I'll see if I can dig around and figure out which driver it should be using. – ArrayBolt3 Sep 25 '22 at 07:19
  • To be honest, I don't know how i can find out his model number... – mIbI Sep 25 '22 at 07:21
  • I dont think so. I cant get any internet connection by any way, so it means "git" Just dont gonna work – mIbI Sep 25 '22 at 08:06
  • Getting the driver installed will require some sort of Internet connection for downloading it (well ok technically there is a way to do it without Internet on the WiFi-less machine but it is extraordinarily difficult). Most people get Internet during WiFi driver installation by plugging in an Ethernet cable or tethering with their smartphone. – ArrayBolt3 Sep 25 '22 at 08:24
  • But which drivers do I need exactly? – mIbI Sep 25 '22 at 08:26
  • The linked answer contains a link to the driver, as well as all the instructions for installing it. – ArrayBolt3 Sep 25 '22 at 08:54
