I recently added Ubuntu (22.04.1 LTS) as a dual boot to my windows 11 pc.

Now I have the problem that I can't access the internet because I can't find drivers for this wifi stick.(it says driver free, but that seems to be incorrect because there were drivers for windows)

The stick is: https://www.amazon.de/dp/B07LFC7VDC?ref=ppx_pop_mob_ap_share

lsusb lists the device as 0bda:c811 Realtek Corp. 802.11ac NIC if that helps

I'm pretty new to ubuntu and linux in general

If you need further info ask in the comments.

    Please post the FULL line that lsusb outputs. The ID is essential. – Pilot6 Sep 13 '22 at 16:09
  • That is the full line, I found some drivers on a site but I am not sure how to install them without Wifi I think I will try to do this with ethernet if there's no easier solution. Do I haveto edit the command to find this ID and can you give me an example ID so I know what it looks like. – Micromot Sep 13 '22 at 16:12
  • This is not a full line.There is ID that you didn't post. – Pilot6 Sep 13 '22 at 16:13
  • Drivers from a site are unlikely to work. – Pilot6 Sep 13 '22 at 16:16

    Yeah sorry I overlooked the Id because I thought it was a timestamp, edited the post to include the ID. I meant some github repositorys with drivers from a site, but as I said I'm pretty new to linux and I'm also not sure if those would work so I asked here. – Micromot Sep 13 '22 at 16:17
  • @trondhansen like pilot said it's a different device, but I found another post talking about a wifi card with the same ID: https://askubuntu.com/a/1163018/1630946 I will try this approach with ethernet later. – Micromot Sep 13 '22 at 16:30
  • That's a perfect existing answer. – Pilot6 Sep 13 '22 at 16:31
  • Oh good then I will use that one, thank you for your help! – Micromot Sep 13 '22 at 16:32
  • I wrote almost the same as an answer, because I couldn't find that one. – Pilot6 Sep 13 '22 at 16:32
  • How does this website work, do I have to delete the post when I found a solution or can I mark it somehow? – Micromot Sep 13 '22 at 16:37

Your device is rtl8811cu. You can install drivers this way.

Connect to the internet using Ethernet or your phone and run in a terminal:

sudo apt update
sudo apt install git dkms
git clone https://github.com/brektrou/rtl8821CU.git
cd rtl8821CU
sudo ./dkms-install.sh
