  • Why 18.04? A newer release probably supports that WiFi out-of-the-box. – ChanganAuto Mar 16 '22 at 15:23
  • The 322e:202c is your webcam, and 13d3:3563 is the MediaTek Bluetooth device. Your wireless card is the 7961 as seen in lspci, but that doesn't have any support with kernels lower than 5.14. If you are using an ASUS TUF notebook, then your only viable solution is to install Ubuntu 21.10 or one of the daily builds of the upcoming 22.04 to have full network connectivity. – matigo Mar 16 '22 at 15:23
  • @ChanganAuto I wish to use ROS melodic and to my knowledge it works with 18.04 the best. – Viral Doshi Mar 16 '22 at 15:44
  • @matigo I had previous installed Ubuntu 20 and the adapter were working but i had to downgrade it due melodic running best in 18.04 – Viral Doshi Mar 16 '22 at 15:46
  • If you have specific reasons to use specific versions of Ubuntu on newer hardware, then you may need to compromise by using a different WiFi adapter or using 18.04 within a virtual machine – matigo Mar 16 '22 at 15:52
  • @Viral Doshi There is no Ubuntu 20 – David Mar 16 '22 at 16:00
  • @David I'm sorry, it was 21.10 – Viral Doshi Mar 16 '22 at 16:56
  • @mchid made the changes, thank you. – Viral Doshi Mar 16 '22 at 16:57
  • @matigo I will look into it, I'm not so keen on doing that atm! – Viral Doshi Mar 16 '22 at 16:58
  • @ViralDoshi Thanks. Also take a look at this answer. There is a script you can run and then you can post the output of the script to the Ubuntu pastebin. The script scrubs identifying information and gives a complete diagnostic output for people to inspect. Then, you can post a link to the pastebin in your question. This will help. – mchid Mar 16 '22 at 17:24
  • @ViralDoshi However, if you have already figured out the problem is with drivers, that may not be necessary. – mchid Mar 16 '22 at 17:27
