Old laptop WiFi worked during Debian 12 install but hardly works or doesn't work after install.

Hi.

I installed Debian 12 on a 2007 laptop. The WiFi card is a 'Wireless NIC Intel PRO/Wireless 3945ABG 802.11a/b/g'.

What must be done to make it work again? The firmware-iwlwifi package was installed already.

Thanks.

What does

Code:

sudo dmesg | grep firmware

say? Since you say you already installed firmware.

edit: Might want to check

Code:

rfkill list

also.

This link has instructions and info: https://wiki.debian.org/iwlegacy but the page seems a bit old, but might still work.

Non-free firmware is required, which can be provided by the firmware-iwlwifi package

The Debian installer has non-free firmware, but you may need to add it post-install.

I should also mention that the laptop isn't mine and I don't always have access to it. I was able to connect an old Edimax USB dongle and that works fine. However, I'd still like to get the internal WiFi card working again.

It runs LXDE and the network program is Conman (I've not heard of that before).

I've found 'conman' to be a bit hit & miss in the past & prefer to use 'ceni' if possible.

It might help to know what wireless chipset is in that machine. The command lspci (list pci devices) issued in a terminal should provide that information.

You may have to issue the command as root.

I searched for the package, 'non-free-firmware'. There was a package that came with the Live ISO and I installed that. The WiFi card seems fine now.
