USB WIFI not recognized....

[rich37]

Attempting to install a generic usb wifi addapter. Using the newest Ubuntu, just downloaded and installed. The usb adapter isn't recognized, I have the linux driver on cd, but no idea to make it work. I have typed sudo lsusb, and wifi is not listed. Can someone help walk me thru the install??? TIA

Update. If I open the home group, I see the linux file. I have opened and extracted the file. When in terminal I type sudo./rtl8192cus.run, it says no such file or directory. Still can't figure out what I'm missing. Any help is appreciated......

Is the driver file old or new? Will it compile correctly for your kernel version and gcc version? What is your kernel version? Do you have the necessary build tools, linux headers, et al installed?

If you are unsure about these issues, then let's start at the beginning:

That device is NOT supported by the driver rtl8192cu. It is supported by the rare and elusive driver 8192eu.

I suggest you obtain a working internet connection by ethernet, tethered or whatever means possible. Open a terminal and do:

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/jpostma/rtl8192eu.git
cd rtl8192eu
make
sudo make install
sudo modprobe 8192eu

Is your wireless now working? If not, post:

dmesg | grep 8192

OK, thanks for the reply. I will obtain the correct driver, but I will have to transfer it to the needing computer via a usb drive. Does drag and drop work in Ubuntu, or do I have to do it within the terminal window?

OK so far, In the terminal window, I get to cd rtl8192eu. So it apparently sees that file. When I type make and enter it says - make: *** No target specified and no makefile found. Stop.
What am I doing wrong???

Let's see what we see:

cd rtl8192eu

Press Enter. Now let's list the contents of the directory:

ls

Press Enter. You should see:

clean  dkms.conf  ifcfg-wlan0  Kconfig  Makefile  platform   runwpa
core   hal        include      LICENSE  os_dep    README.md  wlan0dhcp

If you see the Makefile, then proceed:

make

And so on to the end.

Not sure what I'm missing but, I closed the terminal to start fresh. At first I type in sudo lsusb. That lists all the devices. Then I type in cd rtl8192eu it returns- bash: cd: rtl8192eu: No such file or directory. So from there it tried just ls. It returns

Desktop Downloads Music Public Templates
Documents examples.desktop Pictures RTL8192EU Videos

So the file is in the home folder, what am I missing?

[chili555]

I haven't the faintest idea how or where you got a directory named RTL8192EU instead of the expected rtl8192eu unless you renamed it. Here is what happens when I repeat the sequence as a test:

git clone https://github.com/jpostma/rtl8192eu.git
Cloning into 'rtl8192eu'...
remote: Counting objects: 403, done.
remote: Total 403 (delta 0), reused 0 (delta 0), pack-reused 403
Receiving objects: 100% (403/403), 1.65 MiB | 665.00 KiB/s, done.
Resolving deltas: 100% (141/141), done.
Checking connectivity... done.

So it creates the folder and puts all the files in it.

Next I change directories:

cd rtl8192eu

And list the contents:

ls

And I clearly see:

clean  dkms.conf  ifcfg-wlan0  Kconfig  Makefile  platform   runwpa
core   hal        include      LICENSE  os_dep    README.md  wlan0dhcp
