iwl3945 Problem
- Inicie sesión o regístrese para enviar comentarios
Hello,
I'm trying to make the *Intel PRO/Wireless 3945ABG WiFi adapter working
with my custom Trisquel installation. I have got the non-free ucode from
the following URL. I just copied the iwlwifi-3945-2.ucode to the directory
/lib/firmware.
http://www.intellinuxwireless.org/iwlwifi/downloads/iwlwifi-3945-ucode-15.32.2.9.tgz
I know that it is non-free, but I don't have any other option as my client
want to use the 3945ABG.
Now the problem is that while booting I'm getting an error message
The output of dmesg:
*

The 3945ABG is detected, as the driver iwl3945.ko is already present in the
Trisquel-Slaine.

Please suggest me, how can I make the 3945ABG working with Trisquel.

I'm sorry but you won't find help with non-free software here this is the wrong place to ask. We advise you to do one of a few things.
1) Check h-node for a wireless card that works with all free software.
2) Consider buying a card from Think Penguin (banner on lower right side of the site) which will for sure work with Trisquel.
3) Contact the manufacturer and voice your displeasure that their hardware requires non-free software and make your voice heard.
Hi there,
if your client wants to use a device which needs non-free firmware then you will need to use another distribution. Trisquel or more specific the Linux libre kernel does not support loading firmware.
It really makes no sense to use Trisquel and install a non-free kernel in order to use non-free firmware.
You should speak with your client and ask if a free supported WLAN stick is acceptable.

compile it against the current version of the Linux-Libre Kernel and
install the newly compiled driver (iwl3945.ko), still the driver will not
find the non-free ucode?
Or is that a restriction implemented in the linux-libre kernel as part of
deblobbing ?
Please clarify.
Thanks,

Jos,
the later one. As far I know the abilities to load non-free firmware files is completely removed / disabled in the linux-libre kernel.

That isn't quite correct. Not all firmware is non-free (carl9170 for instance) and the drivers have not been disabled or removed either. I believe the majority of drivers that load non-free code are still present and functional in Trisquel. It is the non-free firmware which has been removed and why such devices do not work.
I highly recommend all users avoid non-free firmware and drivers regardless of the distribution. Even if you do not agree with the ethical implications there are technical ones everybody generally agrees on across the GNU/Linux spectrum.
It would be great if more people avoided software like Adobe Flash too. The non-free driver/firmware issue I think is a bigger one right now though simply because without there being freedom friendly hardware generally available moving to a free distribution doesn't work. In comparison if Adobe Flash doesn't work there are generally alternatives that do even if they aren't as good (eztakes.com, youtube (this one is not completely freedom friendly), etc vs netflix or hulu)
If you aren't willing/able to ditch non-free software completely move to a distribution which includes some of the non-free components and makes it easier to ditch the non-free ones as time/ability/money permit. Then at a later date you can move to a free distribution entirely.
All this said using GNU/Linux with non-free software is destructive to the goals of the free software movement and it should be avoided. Using non-free software or non-free distributions in general hinders the message of the free software community; that the broader GNU/Linux community does not accept non-free software.

One of the short comings of using Trisquel is the lack of non-free support and the parroting of that fact. Word of advice... don't mention it's non-free. ;)
What's the exact make and model of the wireless card? Is it integrated? Obviously, you know that what you specified is the chipset for that NIC.
I ask because one of the great things about the GNU World is that while one project maybe non-free there may or may not be other Free projects for the same thing; i.e. project forking or driver compiling. Warning, a lot of times the drivers are experimental. But, you can help the community by using it and reporting bugs to the project developers.
Another possibility is that if you were able to get it to work on a previous version of Trisquel then you should be able to get it to work if you updated. You just have to use the software in the old repos. This way people can't bark at you for using non-free software. It came from the Trisquel repo... you're just using backdated/outdated software on purpose.

How can I find it? lspci shows the following output. The wireless card is
inside the Toshiba satellite laptop.
Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

would be helpful. The current kernel (2.6.35-28) will detect that.

Is it possible in my case? I mean, will 3945ABG work with any previous
versions of Trisquel (or linux-libre kernel) ? Please help.

What model is the Toshiba? I have 5.5 on my Satellite as well. No issues with wifi... yet.

The lack of non-free software is actually a benefit in my humble opinion. It ensures you aren't being locked into anything, prevented from doing something, etc.
For example if you purchase a laptop with Trisquel and everything works it should continue to work with future versions of GNU/Linux.
This is not to say there is zero chance of having a problem in the future. However the difference is that bugs which get introduced can be fixed and there isn't a single that you have to rely on for continued support.
Compare this to a non-free component one is reliant on. Most GNU/Linux users today are dependent on Adobe Flash for access to a variety of web sites. Adobe has discontinued Flash support for Firefox on GNU/Linux and now these users won't be able to get support from a third party since the code is not free.
Many devices are no longer supported on any platform due to non-free components. This includes graphics cards, modems, printers, and other devices. Sometimes companies have gone out of business although in most cases the companies which released non-free drivers for GNU/Linux, Mac, or Microsoft Windows have simply discontinued support and thus a user is left vulnerable or with non-functioning hardware.
In regards to this issue it looks like that is an Intel wireless card and Intel's firmware is non-free.
If it had been an ethernet card we do have a USB chipset which is free software friendly. Both 10/100 and now 10/100/1000. The later I don't believe will work until the next release of Trisquel though. We don't have any PCI cards at the moment although we shouldn't probably look into PCI/PCIe as well just to ensure we have a complete catalog.
