How to fix network adapter not working during installation?

Postby Hardenz » 2019-12-05 19:25

Hi guys

I'm new to Linux so please keep it light.

I put the USB-install version of Debian on a USB-stick. However during installation the internet connection is not working. How do you get it to work? It says that some firmware files for the network adapter is needed and to search on the USB-stick. But they are not found. Which is not surprising since I did not put them there.

Then I tried to download the full version of Debian but that was too confusing.

The network adapter is Intel I217LM/V and I218LM and Qualcomm Atheros QCA9000 Series Wireless LAN Driver

What do do?

Thank you in advance.

There is 1000s of answers to this all ready posted on this forum, and has documentation about it, but any way,... one more time :
6.4.1. Preparing a medium

Official CD images do not include non-free firmware. The most common method to load such firmware is from some removable medium such as a USB stick. Alternatively, unofficial CD builds containing non-free firmware can be found at ... -firmware/. To prepare a USB stick (or other medium like a hard drive partition, or floppy disk), the firmware files or packages must be placed in either the root directory or a directory named /firmware of the file system on the medium. The recommended file system to use is FAT as that is most certain to be supported during the early stages of the installation.

Tarballs and zip files containing current packages for the most common firmware are available from: ... /firmware/

There are also CD images that include non-free firmware for most devices:

Also this is usefull:

And another more time as I was just writing while the above was posted and I don't want to waste it. :wink:

I don't understand what you mean by "USB-install version" Most of the images can be written to USB to install. Also what is "full version"? Generally you have choice of netinstall or DVD version with several others you don't want to know if you're not experienced. There is a live version from which you can boot Debian without installing it, and a full installer which has more advanced options.
Probably the easiest way for someone new to Debian is to use the "unofficial" live image which probably includes the non-free firmware you need. You still need to decide which desktop you want to use first. KDE, Xfce, Gnome, LxQt, LXDE, Cinnamon, and Mate are all available. ... so-hybrid/

Are you trying to use ethernet connection or wireless?
For wireless using your current USB installer you may need to download the package firmware-atheros from the repo and put it on a second USB stick and point the installer to that. Ethernet usually works out of the box. ... re-atheros
