Kubuntu 18.04 wireless USB driver install

[h8ids]

I'm new to Linux.
I have a Cudy USB WiFi thumb drive adapter that I'm attempting to install.
Kubuntu 18.04 sees the device. But it doesn't install a generic driver.
In addition it doesn't think that any proprietary drivers need to be installed.

I do have a drivers for it. (Linux, Windows and MAC)
Not certain how to go about installing a driver on Linux.
My user account does have administrative access; however, I'm not able to install/copyto the root folders.

Needing direction.

FYI: 18.04 is no longer supported.

But we still might be able to provide help with the dongle.
We need more information

Plug the dongle in, and in a terminal enter this command to spit out USB hardware info,

lsusb

This will give us ID numbers to narrow down what specific chip you have.
It is very likely that those driver files you need to be compiled, not just copied somewhere, and there probably will be better/newer drivers for it available, maybe even easily installable.

Another thing to try is to grab Kubuntu 20.04 and make a live USB for that, and see if the Wifi dongle works there. It might possibly have better support in the newer OS, assuming your computer is 64 bit capable.

Here's the lsusb results.

The driver for the CUDY dongle (model WU1300) is made by Realtek
It came with the dongle and is the most recent version for Ubuntu 18.04

The system is 32bit.

Thank you for your support!

The instructions available from Cudy's website for the driver file should work, you don't need to copy the files anywere needing root acces, but you will need to do some work in the terminal.
The latest download, and install guide can be found here:
https://www.cudy.com/wu1300_software_download
This will require you to rebuild this every time you get a new kernel version, possibly even for minor security updates.
Not mentioned in the guide will be the need to install some supporting packages:


sudo apt install linux-headers-$(uname -r) build-essential

Then follow Cudy's guide.



Another option - and probably the one I recommend - is to grab an even more current version of the driver such as this:
https://github.com/morrownr/88x2bu-20210702
This page has very abundant documentation on how to install them using DKMS, which will automatically rebuild the driver with every kernel update as needed.
The page is long, as it includes instructions for most Linux platforms, but you just need to follow the ones specific to Ubuntu.They are very thorough, and quite simple to follow, so it should be pretty straightforward, even for a new user.
There are other versions of this on Git, but the instructions for the one I linked to are very good and clear.


Also linked to are potential alternative dongles, if you end up having to go that route

Thank you for your thorough support.
I will give it another whirl.

Stuck again.
Here is the error I'm receiving.

Attempted install under default user and root account.
Unfortunately both methods yielded the same results.

Attached image shows the results

A couple if tips:

DO NOT USE SUDO until any instructions tell you to. You only need root access when actually installing the compiled bits, at the end.

Use Dolphin to navigate to the directory, then hit f4 to open a terminal panel that will be open in that directory.

Instead of screenshots of terminal output, simply copy the text, and paste it into a reply. Much easier for others to read, and do copying of their own


Oddly. the problem in your screenshot seem to be that the code is looking for very old kernel files. The instructions for installing this may be crap, outdated, etc
Looking at them again, they are crap, and don't mention what extras you need to install.

I greatly suggest using the github link I mentioned, read it carefully, and follow all the steps precisely, except for the ones explicitly for anything not Ubuntu/Debian/Mint. The instructions will first install all the needed utilities and dependencies, and then download the code. They have scripted the install so there are very few steps to actually perform. You should be able to skip the prompt to edit the config file, by hitting 'y' when it asks.

I tested the instructions as given, and everything does build and install as expected (on 20.04 - 18.04 *shouldn't* be any different, hopefully), but of course I cannot test it for functionality.

Thank you.
I will try again.
