I am trying to install my dwa 181 wifi usb adaptor's driver on ubuntu but it's not working, i have downloaded the official linux driver on d-link website https://support.dlink.com/ProductInfo.aspx?m=DWA-181-US and i spent 7 hours searching on different websites how to install the driver but without any result.

So, there's something i can do to install the driver?

  • Probable answer: https://askubuntu.com/questions/1312297/usb-wifi-adapter-is-not-working-on-ubuntu-20-04-1-lts/1312324#1312324 Welcome to Ask Ubuntu. – chili555 Feb 07 '21 at 21:13
  • ok i modified the question and i have also tried the probable answer but it's not working because whatever i use make or dkms, make fail giving some errors – Ric3 cir121 Feb 07 '21 at 21:29
  • What errors, exactly? If the output is lengthy, paste the result here and give us the link: http://paste.ubuntu.com – chili555 Feb 07 '21 at 21:29
  • This is what the terminal give when i run "sudo make" https://paste.ubuntu.com/p/gSkYxkFXxv/ – Ric3 cir121 Feb 07 '21 at 21:35
  • And you are quite sure this is the file you acquired by git at the link I gave and not a leftover from a previous unsuccessful attempt? If you have any previous attempts, please delete them first. – chili555 Feb 07 '21 at 21:41
  • this is the same result of many files that i have downloaded online and the original driver on the d-link website – Ric3 cir121 Feb 07 '21 at 21:42
  • Is this Ubuntu 20.04 or 20.10? – Jeremy31 Feb 07 '21 at 21:42
  • it is ubuntu 20.10 – Ric3 cir121 Feb 07 '21 at 21:43
  • Please delete *all* previous attempts now and git clone the version I suggested from git. I just tried it and it 'makes' without any errors at all on my 5.8.0-41 system. – chili555 Feb 07 '21 at 21:46
  • it's giving me an error on the first dkms command "Error! DKMS tree already contains: rtl88x2bu-5.6.1 You cannot add the same module/version combo more than once. " – Ric3 cir121 Feb 07 '21 at 21:49
  • What do these commands tell us? `sudo modprobe 88x2bu && dmesg | grep 88x2` and also: `sudo dkms status` – chili555 Feb 07 '21 at 21:52
  • `ric3cir121@ric3cir121:~/Scrivania/rtl88x2bu$ sudo modprobe 88x2bu && dmesg | grep 88x2 modprobe: FATAL: Module 88x2bu not found in directory /lib/modules/5.8.0-41-generic ric3cir121@ric3cir121:~/Scrivania/rtl88x2bu$ sudo dkms status rtl88x2bu, 5.2.4.4: added rtl88x2bu, 5.6.1: added` – Ric3 cir121 Feb 07 '21 at 21:54
  • In dkms status, we see "added" and not installed, meaning that they did not compile correctly. Let's remove them all: `sudo dkms remove rtl88x2bu/5.2.4.4 --all` and also: `sudo dkms remove rtl88x2bu/5.6.1 --all` Then try the git version again from the dkms steps. – chili555 Feb 07 '21 at 22:01
  • Thanks a lot! It worked! – Ric3 cir121 Feb 08 '21 at 06:19
