    Re: Error 127 and 2 (Wifi Adapter)

    I'm extremely new to Linux. I used Ubuntu 20.04 and I'm trying to install a wifi driver. Here is the link: https://www.amazon.com/dp/B07QC3XQHW..._42xWEb9NXVR9V
    (Drivers are included on that page in the "about" area)
    I did install.sh and got 127 error and fixed that by using build-essentials but then got compile make driver error: 2. Did something with updating linux-headers- generic and that didn't work. Could someone please download the driver's and write a step by step instructions on how to install it?

    Welcome.

    One of the reviewers explained a much better method.

    What do you mean? I just need a decent guide to set this thing up.

    I believe that CelticWarrior is referring to this: https://www.amazon.com/gp/customer-r...SIN=B07QC3XQHW …but CelticWarrior can clarify if I am wrong.

    On my Amazon page, it was the second review from the top.

    I didn't see that, my bad.
    I thought you had to use install.sh file to install it.
    Also I don't understand how to do step 2...

    I'm afraid you're in for a bit of an adventure:
    https://help.github.com/en/github/cr...g-a-repository
    …and:
    https://www.howtogeek.com/451360/how...ub-repository/
    It's something of a learning curve, but I'm afraid there's no getting around the complexity. That's just how git works.

    Re: Error 127 and 2 (Wifi Adapter)

    Anticipating your next question, a bit of web searching directs us to the following git repo: https://github.com/brektrou/rtl8821CU

    That's about as far as I can help you with this. It's a big minus when I have neither the WIFI dongle to work with nor the in-depth WIFI knowledge.

    What I can do is move your thread to the Network and Wireless subforum where the network gurus are more likely to see it.

    Re: Error 127 and 2 (Wifi Adapter)

    Uh. Confused. First, which link do I use for cloning, second, it doesn't look that hard to clone? That USB GitHub thing just says for the terminal to use "Git clone (url here)"
    (Which I assume I'll need a temporary wifi connection to do)


    Also that would be helpful

    Yes, you need a temporary internet connection. But before going any further please post the relevant line that identifies the dongle by running 'lsusb' in terminal.

    What I said about the reviewer with Git assumes the chipset inside is still the same as it was an year ago. Manufacturers tend to use different chipsets for the same model, different revisions.

    Re: Error 127 and 2 (Wifi Adapter)

    The instructions were linked to in my second post. The actual repo that you wish to clone is in my third post.

    If you read through the git site's help page, it explains in detail the process that you go through. How to find the link in the repo, how to start the cloning process, etc. It's seven steps of command line instructions. As said, it's a learning curve. Please read through the instructions before trying.

    You will need a wired connection first. You must have access to the internet before you can clone the git repo. Since your WIFI is not yet working, you will have to bootstrap up to WIFI functionality by first making use of wired access.
