Check dmesg for what firmware you tried, but failed to get.

$ dmesg | grep -i firm

$ dmesg | grep -i fail

Currently on jessie, but shouldn't have changed much between releases. If dmesg shows a specific file name, you could use apt-file to locate the exact package that you need.

$ apt-file find rtl8168e-3.fw

Code:

firmware-realtek: /lib/firmware/rtl_nic/rtl8168e-3.fw

$ sudo apt-get install firmware-realtek

For my current machine anyway.

What is the name on the usb adapter?

Command lsusb may be a place to start.

Hello and welcome to the forum

If you would, please connect the system to the internet using an ethernet cable and then open a terminal and run the following commands...

Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

Then navigate to the location of the text file the script created and post the contents (or a link to them) in your next reply. Thanks!

Regards...

Should be using rtl8192cu

http://www.thelinuxrain.com/articles...altek-chipsets

Has an idea about the reason maybe.

monojeffrey · 07-08-2017, 01:51 AM

installed the driver using the following way
actually did a cloning (git) to download the driver

pre-requisites:

apt-get install linux-headers-$(uname -r)

apt-get install git
git clone https://github.com/lwfinger/rtl8188eu
cd rtl8188eu/
make all
make install
mkdir /lib/firmware (since this one was existing)
make install
insmod 8188eu.ko

reboot the machine
