I was installing Debian. But, I know that I have installed wireless connection system manually in Debian.

enter image description here

But, I couldn't install wireless connection while installing Debian. I had connected Ethernet although, I couldn't install it. So, I had skipped it. I downloaded iwlwifi-6000g2a-ucode-18.168.6.1.tgz from Intel Wireless connection. I had tried to some commands also

apt-get install linux-firmware
apt-get install firmware-iwlwifi

Both had returned "unable to locate package". When I had extracted wlwifi-6000g2a-ucode-18.168.6.1.tgz, I just found three files. I don't think that I can do something with them. So, how can I install wireless network in Debian.

enter image description here

I had made changes to /etc/apt/sources.list

#

deb cdrom:[Debian GNU/Linux 10.10.0 Buster - Official amd64 NETINST 20210619-16:11]/ buster main


#deb cdrom:[Debian GNU/Linux 10.10.0 Buster - Official amd64 NETINST 20210619-16:11]/ buster main


deb http://deb.debian.org/debian/ buster main contrib non-free
deb-src http://deb.debian.org/debian/ buster main contrib non-free


deb http://security.debian.org/debian-security buster/updates main contrib non-free
deb-src http://security.debian.org/debian-security buster/updates main contrib non-free


buster-updates, previously known as 'volatile'


deb http://deb.debian.org/debian/ buster-updates main contrib non-free
deb-src http://deb.debian.org/debian/ buster-updates main contrib non-free


This system was installed using small removable media


(e.g. netinst, live or single CD). The matching "deb cdrom"


entries were disabled at the end of the installation process.


For information about how to configure apt package sources,


see the sources.list(5) manual.


root@Istiak:/home/istiak# lspci | grep -i network
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04)
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)

I don't have modprobe also.

    Confirm : add "contrib non-free" to deb lines in sources.list : Then no issues .... all firmware installs OK. – Knud Larsen Jun 27 '21 at 11:51
  • @KnudLarsen But, I wonder I don't have modprobe in system. Even, I can't install it. Why? – Softunes Jun 27 '21 at 11:52

    Was it with Debian 9 that su changed ? ... You now have to do su - to use most root commands, including modprobe command and apt install [package] .https://unix.stackexchange.com/questions/7013/why-do-we-use-su-and-not-just-su – Knud Larsen Jun 27 '21 at 12:00
  • @KnudLarsen gotcha :) – Softunes Jun 27 '21 at 13:17

I had mentioned in the comment,

@Canina‭ I had updated my system also.

But, actually I had updated my system before making changes to /etc/apt/sources.list.

At first, you have make some changes to /etc/apt/sources.list. You have to add following line to every line which starts with deb (in /etc/apt/sources).

contrib non-free

Then, you have to update your system.

sudo apt-get update && apt-get upgrade

Then, install firmware-iwlwifi. (Your default user won't be sudoers, that's why you have to work as a root user su)

apt-get install firmware-iwlwifi

Then, you will have to reboot your PC.
