  • As a general rule of thumb, Debian is restrictive about installing during the initial installation what, according to [the Debian Free Software Guidelines](https://www.debian.org/social_contract#guidelines), is non-free software.
  • That's why the installer offers you to provide the firmware files from a different media, in case you need to get networking up and running to proceed with the system installation.
  • However, the firmware for the Intel Wireless 6205 actually is packaged by the Debian project, in the `non-free` component, in the `firmware-iwlwifi` package. [See here](https://packages.debian.org/stable/firmware-iwlwifi).
  • It even looks like they currently package version 18.168.6.1 of that particular firmware, which matches what you downloaded manually.
  • For other wireless network cards, a good place to start is to search [the current stable distribution for packages with names containing `firmware`](https://packages.debian.org/search?keywords=firmware&searchon=names&suite=stable&section=all), then look through that list to find likely candidates and check the package details to see if your particular card is listed.
  • To get *your* particular wireless network card working, it should be enough to:
  • * Install the `firmware-iwlwifi` package from the `non-free` component normally using `apt-get` (notice that the package name that failed to install for you is different: `iwlwifi-firmware`)
  • * Your apt sources already include the `non-free` component, but if they didn't, you would need to add it to the appropriate file (either `/etc/apt/sources.list` or one under `/etc/apt/sources.list.d`, depending on exactly how your system is set up)
  • * Either:
  • * add a single line with the module name `iwlwifi` to `/etc/modules`,
  • * *or* add a new file in `/etc/modules-load.d` such as `wlan-local.conf` that contains a single line with the module name `iwlwifi`
  • * Reboot
  • * *or* `sudo modprobe iwlwifi`, but I find that rebooting provides a nice sanity check that things will also work later
  • Once the system is back up, you should be able to:
  • * see that the `iwlwifi` module is loaded (using `sudo lsmod`)
  • * see that the wireless interface is up, but not connected to a network (using `ip addr sh`)
  • * use the wireless interface to connect to a network (probably using NetworkManager; `sudo nmcli wifi list --rescan` might be a reasonable starting point), after which it should also have an IP address

As a general rule of thumb, Debian is restrictive about installing during the initial installation what, according to [the Debian Free Software Guidelines](https://www.debian.org/social_contract#guidelines), is non-free software.

That's why the installer offers you to provide the firmware files from a different media, in case you need to get networking up and running to proceed with the system installation.

However, the firmware for the Intel Wireless 6205 actually is packaged by the Debian project, in the `non-free` component, in the `firmware-iwlwifi` package. [See here](https://packages.debian.org/stable/firmware-iwlwifi).

It even looks like they currently package version 18.168.6.1 of that particular firmware, which matches what you downloaded manually.

For other wireless network cards, a good place to start is to search [the current stable distribution for packages with names containing `firmware`](https://packages.debian.org/search?keywords=firmware&searchon=names&suite=stable&section=all), then look through that list to find likely candidates and check the package details to see if your particular card is listed.

To get *your* particular wireless network card working, it should be enough to:

 * Install the `firmware-iwlwifi` package from the `non-free` component normally using `apt-get` (notice that the package name that failed to install for you is different: `iwlwifi-firmware`)
 * Either:
   * add a single line with the module name `iwlwifi` to `/etc/modules`,
   * *or* add a new file in `/etc/modules-load.d` such as `wlan-local.conf` that contains a single line with the module name `iwlwifi`
 * Reboot

Once the system is back up, you should be able to:

 * see that the `iwlwifi` module is loaded (using `sudo lsmod`)
 * see that the wireless interface is up, but not connected to a network (using `ip addr sh`)
 * use the wireless interface to connect to a network (probably using NetworkManager; `sudo nmcli wifi list --rescan` might be a reasonable starting point), after which it should also have an IP address
