Subject: Wireless 7260 on Debian 11

Hi,

I just purchased a Dell Latitude 3340 on eBay and I tried installing
Debian 11 on it but I am unable to get the wireless network to enable.
The wireless was working perfectly in Windows 10. According to lshw the
laptop uses a Wireless 7260. I first tried running 'apt install
firmware-iwlwifi', but Network Manager just says that the wireless
network is unavailable. I then tried downloading
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-7260-17.ucode
and copying it into the /lib/firmware folder, but that didn't work
either. Is there anything else that I can try? Thank you in advance for
your assistance.

Sincerely,

Chris

What says dmesg - typed in a terminal?

Here on my Debian/unstable AMD64:

root# dmesg | egrep -i 'iwl|ucode|firmware'

[ 54.675939] iwlwifi 0000:01:00.0: firmware: direct-loading firmware
iwlwifi-6000g2b-6.ucode
[ 54.676668] iwlwifi 0000:01:00.0: loaded firmware version
18.168.6.1 6000g2b-6.ucode op_mode iwldvm
...
[ 58.417970] iwlwifi 0000:01:00.0: Detected Intel(R) Centrino(R)
Advanced-N 6230 AGN, REV=0xB0

You need to install firmware-iwlwifi Debian package.

# dpkg -L firmware-iwlwifi | grep iwlwifi-72
/lib/firmware/iwlwifi-7260-17.ucode
/lib/firmware/iwlwifi-7265-17.ucode
/lib/firmware/iwlwifi-7265D-22.ucode
/lib/firmware/iwlwifi-7265D-29.ucode

Cannot say if the firmware-iwlwifi package ships the latest firmware
you need on Debian-11 for your wifi-card.

Here I have:

# dpkg -l | grep firmware-iwlwifi | awk '/^(ii|hi|rc)/ {print $1 " "
$2 " " $3}' | column -t
ii firmware-iwlwifi 20221214-3

Hope that helps.
