Hello Readcash Friends! :0)

I was faced with a big problem with Linux on a Laptop. I share it because it can help people with a similar problem.

I had to install Linux on two machines to a friend. Machines not new and therefore not very efficient. This required finding the right version of Linux for each machine. A Dell 32-bit Desktop, and a 64-bit Laptop Medion.

Preparation of bootable USB keys with Linux version for each machine.

The one who asked me the problem, the laptop, is a Medion Notebook S4219. It was a question of finding a compromise between good performance and comfort of use. For someone who wants to permanently switch from Windows to Linux, Linux Mint is a great choice. But there, big problem: once installed the system did not detect the WiFi card, and therefore: no network available. This Medion machine does not have an Ethernet slot, no RJ45 connection possible. Forget also a possible internet connection sharing on your smartphone in BlueTooth, of a few kb/s only, for daily use. Pain! But.. this option still allowed me to recover the necessary to solve the problem.

First thing was to detect the Chipset, the devices, and find the Wifi card to retrieve the right drivers.


No wifi there

lspci | grep -i network

Still nothing there


Bingo! Here it is! Ok, its an internal USB Wifi card. A Realteak one, drivers ref after a quick researsh: RTL8723BU

You can get them on Github, but you need to compile the drivers after download.

git clone

Prepare it & compile it:


cd rtl8723bu/

make -j 8

sudo make install

sudo modprobe -v 8723bu

Done! Wifi on.. Hey hey hey! :0)

A quick additional note here.

In linux, most of the wifi cards work through closed source binary firmwares, released by manufacturers.

In debian, you can edit your /etc/apt/sources.lst file to add non-free repositories.

then do an apt-get update then:

apt-get install firmware-linux-nonfree

this is going to install 100s of wifi-cards, and after a reboot, most of these cards will come up in the system.

I suppose the new software detecting the exclusive content doesn't scan the old ones? /

It doesn't make any sense to do it - there might be people who copied your articles and you have nothing to do with it. There only one moment we can be sure about anything - the moment you first publish it, after that - we can no longer be sure whether any copies were there before, after the publishing date, were they done by you or by anyone else.
