During installation I got a few pop ups stating that hardware needs non-free firmware files to operate. At that time I didn't have those files so I continued with the installation, but now my now system is not able to recognize wifi. I tried installing firmware but whatever from searching from didn't at all work.

The missing files are:

  • rtleifi/rtl8723befw.bin
  • rtleifi/rtl8723befw.bin

Now I completed the installation, how can I install the firmware?


You need to enable non-free first: edit /etc/apt/sources.list, and at the end of lines ending with main, add contrib non-free. You'll end up with something like

deb http://ftp.fr.debian.org/debian jessie main contrib non-free


Then update your repositories and install firmware-realtek:

apt-get update && apt-get install firmware-realtek

That will provide the necessary firmware files.


If you have a wired internet connection you can install sudo apt-get install firmware-linux-nonfree

Alternative way in Debian 8 Jessie:

Download firmware.zip or tar.gz from here :

and extract all files of the zipped archive in folder /lib/firmware and then restart.
See also Debian Wiki :

Provide Firmware during installation:
Just for the record when i want to be sure that all recent firmware will be available during a fresh Debian Jessie installation i follow these steps:

  • I download the Debian 8 iso image i like (stable, testing, etc)
  • I burn Debian iso image to a usb stick
  • I download seperately the package firmware.tar.gz
  • I copy firmware.tar.gz inside folder "firmware" of the installation cd.
  • I extract firmware.tar.gz inside folder "firmware" of installation cd by using "extract here" option
  • I accept any overwrite messages.
  • Finally i boot with usb stick and firmware it is just there for sure.
  • PS: I do the same procedure even if the Debian iso image claims that contains nonfree firmware, because in reality it has turned out that firmware maybe missing even from such iso images.
  • It says there is no such package... – Sarfraz Robo Rex Jan 11 '17 at 9:04
  • If you run apt list "firmware*" do you get any results? Also make first sudo apt-get update && apt-get upgrade && apt-get dist-upgrade – George Vasiliou Jan 11 '17 at 9:13
