Intel Releases Linux Driver For Centrino WLAN

timothy posted more than 10 years ago | from the usefulness dept.

Wireless Networking 285

Werner Heuser writes "Finally Intel has made their different announcements about Linux support for the WLAN part of the Centrino technology become true. Though not yet officially announced an Open-Source driver with included firmware is available at SourceForge. The driver is still experimental and supposed to work with 2.4 Kernels as well as with 2.6 ones." (See these previous stories for some background.)

On my screen FireFox renders seveal times the word "Intel"... but maybe It's just me.

They are releasing the specs and a semi-working beta to the community. Their developers AND the voluntary ones will improve the driver.

That's EXACTLY what linux users and developers have been asking for ages, i reckon.

It's a win-win situation: Intel gets a fully working and highly optimized driver for free and in a shorter time, and the community gets a GOOD driver for free.

Now tell us: what's wrong with Intel's approach, please.

Intel Feeling the Pressure? (5, Insightful)

This really feels like Intel's finally feeling its stranglehold on the industry wavering a little (given AMD's 64bit success). I'd like to believe that this is going to lead them to start treating us like customers, rather than prisoners. Certainly, this is a nice first step.

Do not encourage the use of NDISWRAPPER! Someone will probably moderate this as Troll, but come on - we all know that having such a "fallback option" makes the hardware makers relax more when it comes to releasing natively running, opensource Linux drivers!

Re:NDISWRAPPER (4, Interesting)

Zakabog (603757) | more than 10 years ago | (#8522049)

But for them to relax more they'd have to be working on something in the first place, most of the hardware makers that are willing to support linux are gonna do it with the best drivers they can, not have people running their software in linux with some little hack. And the ones that don't support linux don't care that some little app lets people run windows drivers, they weren't going to support linux anyway it's not worth it for them. If NDISWRAPPER works then people should use it, I know I'd deffinitely use it if it supports my laptops network card (haven't been able to get this thing to work at all, some fairly old lucent technologies wireless card, I think there is support for some newer version of this card but not mine.) I'd use a newer card with linux support but the laptop itself doesn't support these (dunno why, tried some netgear card it didn't like that very much I think the PCMCIA slot in my laptop is 16 bit or something like that it's an old laptop.)

Stealing Windows Driver (1, Offtopic)

darkmeridian (119044) | more than 10 years ago | (#8521918)

I use ndiswrapper with my Truemobile 1400 card with gentoo. (Sorry. Had to say it. :P)

ndiswrapper 0.5 is absolutely great. It automagically installs using the windriver.inf file and autoloads. Downloads at >500 kb/s sustained. Does not crash.

I wonder if there can be more projects like this one that essentially steal windows drivers and puts them onto linux. There should be more unified driver APIs like ndis out there, right? I wonder if we can get rid of winmodems using wrappers.

On a sidenote, the Cisco VPN client 4.0 hangs on 2.6.3. It works if you switch to a new console. No one knows how to fix it yet. I was using the anomalistic patch, but nothing yet. I guess I have to backpatch the kernel. Yuck.

Re:Stealing Windows Driver (2, Informative)

Gerald (9696) | more than 10 years ago | (#8522025)

Have you tried capturing raw 802.11 frames with NdisWrapper? (Hint: Most Windows drivers don't support this, since NDIS doesn't provide a standard interface for it. Most Linux and FreeBSD drivers do.)

Re:NDISWRAPPER (small warning) (0)

Anonymous Coward | more than 10 years ago | (#8522106)

Ndiswrapper works great for some, but I tried for 2 whole days to get my 802.11g wireless card to work without Oopsing, and failed, despite it having a supported chipset.

I now have a prism chipset, but that driver also has problems - no signal is registered after a day or so of being connected. Reloading the driver brings the connection back, so its probably a software problem.

I can remember the day when I could only get spotty support for most hardware on my Linux box. Buying a computer was complicated if I wanted to use Linux -- I might only have one or two choices for a component (i.e. soundcard) because the drivers came from the community. This is a great sign, if Intel starts supporting all of their products under Linux, other vendors will follow suit, and it won't be long before you'll see Lindows boxes alongside the Macs at CompUSA!

Yeah I know pretty soon we might get some linux support from other companies! Like NVidia, 3Comm, Ceative Labs, ATI, Netgear, Linksys, man pretty soon I'm gonna be able to build a sweet linux computer!

*Looks at his own two linux computers*

Oh...

I'd actually be more excited about Intel's decision if they had any products I actually wanted. I don't know of any companies I'd buy from whose products don't work in linux one way or another. Sure some things might not work, but I haven't run into anything in the past 2-3 years that I couldn't get working in linux although setting up my ATI card was a real pain. There are even a few no name devices that I wouldn't expect to work, that just happened to have support since they use the same chipset as like 40 other no name devies.

Quit bitching. IICRC, NVidia doesn't own all the code in their drivers and anyway, why should they be forced to disclose stuff they consider a trade secret? They provide solid, working drivers for an OS used by like 1% of the desktop market. That's pretty impressive, imo.

Re:Open Source Driver + Firmware (1)

wangmaster (760932) | more than 10 years ago | (#8521880)

I think it's a little of both. The firmware portion still hides alot of what the hardware does, but, since the driver is entirely opensource, at least you know what the kernel portion is doing. It's one step closer to opensource than NVidia, but I don't think it's 100% there (still, it's great). I've been using the prism54 drivers with the miniPCI 54G card I bought and they do the same thing, opensource driver, closed firmware.

Re:Open Source Driver + Firmware (5, Insightful)

vranash (594439) | more than 10 years ago | (#8521893)

Given the supposed lack of foresight in their hardware design that most wlan vendors have taken recently (using basically 'soft wlan' cards), it is probably more akin to a 'partially closed driver', in that you probably won't have access to the channel frequencies, adding new network modes (master, monitor, etc). HOWEVER given that, it should allow future patching to the kernel side of the driver to support whatever future interface changes happen to ensure the card won't suddenly become useless.

IMHO, this is what all wlan dealers should be doing... if you can't give direct access to the hardware due to possible legal/FCC constraints, then you should have firmware to handle the interfacing so that you can at least release firmware interface specs, and hopefully be able to cut down on cross development costs by having your firmware patches enhance both linux and windows functionality while stomping out mutual bugs.

Re:Open Source Driver + Firmware (1)

alex_tibbles (754541) | more than 10 years ago | (#8521959)

Thanks for that.
I agree that it's clearly better to have a large chunk of the driver open-source (even if, as it seems, it did not come from the vendor). Does intel publish the interface to the firmware?

Re:Open Source Driver + Firmware (5, Informative)

alex_tibbles (754541) | more than 10 years ago | (#8521928)

to answer my own question (partly):
"As the firmware is licensed under a restricted use license, it can not be included within the kernel sources. To enable the IPW2100 you will need a firmware image to load into the wireless NIC's processors." From http://ipw2100.sourceforge.net/README.ipw2100 [sourceforge.net] .

So yes Intel is, kind of, supporting Linux driver for the Centrino chip as the pay the guy...

However, I don't beleive this is a priority for them. If it was so, they would have released something that is fully functional... What it seems to me is that they are paying one guy to do it and hope the OS community will jump in and help them out! I don't see any real corporate backing behind this project.

Just because they aren't loudly tooting their own horn by splashing "intel" all over the sf.net website doesn't mean they're not helping/having their people do the work.

That's interesting because the original announcement was sent to LKML by James Ketrenos from the address jketreno at linux.co.intel.com.

Just because they've not put their name all over the site in no way makes this "not released by intel".

I don't get it (5, Interesting)

edbarrett (150317) | more than 10 years ago | (#8521831)

The contact email address is ipw2100<dash>admin<at>linux<dot>intel<dot>co m, the readme says it's copyright intel, but the home page says
This project is intended to be a community effort as much as is possible given some working constraints (mainly, no HW documentation is available)
So intel is not releasing the necessary documentation for the hardware, but has set up a SF project for "The Open Source Community" to figure it out?

Re:I don't get it (4, Funny)

Halthar (669785) | more than 10 years ago | (#8521896)

Maybe they are truly in touch with open source projects everywhere, and when it comes to documentation simply said "screw it, someone else will write it!"

Perhaps this is intels retaliatory snub to MS. It has seemed to me that there have been a few cracks appearing in the wintel alliance, not least the adoption of the G5 succesor for the Xbox2.
perhaps intel will start helping out the open source community a bit in order to piss of Gates and co.?

Re:I don't get it (5, Insightful)

MWelchUK (585458) | more than 10 years ago | (#8521957)

They probably can't release the documentation for some reason, however as long as there are a number of intel people on the project _with_ access to the documentation this isn't as huge a problem as it would otherwise be.

This allows the community to help stear the portions of the code that don't require the documentation and to help them properly tie the driver into Linux.

As long as the code isn't a complete mess it will also be possible to get some understanding of the workings of the chip from the code.

I agree that it is not ideal, however it's better than a binary-only driver.

Hooray! (1, Funny)

Don't bother yet, its not finished (4, Informative)

Anonymous Coward | more than 10 years ago | (#8521853)

TODO

- long/short preamble support
- enhance wireless extension support
- adhoc
- encryption (WEP)
- continue to add support for addtional SW RF kill switch implementations
- "shared" authentication
- transmit power control
- power states support (ACPI)

Yes you read that right. So is there anything this driver does do?

After promising and promising to support Linux we get this. A crappy not finished driver. I suppose I'm supposed to be happy that Intel finally started to work on this after like what, a year after we should have had support? Sorry Intel but screw off. I already bought a PCMCIA Wireless NIC. And I'm sure as heck not going to replace it with you crappy nic and unfinished drivers. Thanks for nothing. Next notebook I buy is going to be AMD powered.

skiflyer (716312) | more than 10 years ago | (#8521874)

Great... this makes me much more pleased about my IBM t41 which is in the mail.

Now, any geeks around Chicago wanna help me get setup? Everytime I install linux on a laptop I only get it 90% correct, and manage to completely bork it based on the other 10% about 6 months down the road.

Re:Woo hoo (4, Informative)

tedric (8215) | more than 10 years ago | (#8522100)

You shouldn't have any trouble with the T41. At least my model works great. IBM (Germany) had a special offer including SuSE Pro 9 (the standard box). Additionally to that I got a special T40/T41 CD that repartitioned the harddrive (15GB Win XP, 45GB Linux ;)) and installed SuSE with all necessary modules. It went really great, no trouble at all.

Also check out www.linux-on-laptops.com. Especially for IBM laptops there are lots of pages out there describing linux installations for various distributions in-depth.

Btw: I ordered my T40p with the optional 802.11a/b/g card (standard is a/b) and installed FC1 - not because SuSE is bad, just because I'm used to RH. The card is manufactured by Philips and works just fine with the modules from madwifi (visit SourceForge). Well, with kernel 2.4.*, I still have some trouble with kernel 2.6.*.

Uh, this is people getting fed up (1, Interesting)

lavalyn (649886) | more than 10 years ago | (#8521917)

And building their own driver.

Like the eepro100 driver from before? Or those Texas Instruments wireless chipsets in the DLink 650+? And a whole mess of other drivers for other devices from hardware companies that won't release technical specifications. Heck, are Broadcom 11g drivers out yet?

Re:Uh, this is people getting fed up (0)

Anonymous Coward | more than 10 years ago | (#8521986)

James is an intel person. They really could do with noting this because at the moment people are screaming bad things when it is an official-ish development.

What about Broadcom? (0, Offtopic)

j0hndoe (677869) | more than 10 years ago | (#8521980)

I've been thinking about buying a new Dell laptop. Most of them come with a choice of Intel or Broadcom wireless adapters. Now, the availability of an Intel open source driver is good news, however, the Broadcom adapters offer better performance (802.11g vs 802.11b) and lower power usage for the same price.

I'll probably be modded to hell for saying this, but I think I would still buy the Broadcom, since it can also be made to work using the various NDIS wrapper projects.

Re:What about Broadcom? (1)

DFJA (680282) | more than 10 years ago | (#8522066)

Can anyone confirm definitively that Broadcom-based devices work with NDISWRAPPER? Last time I tried my Belkin 54g PCMCIA card I didn't succeed, but it may be time to try again, it was a while ago.

But yes, we need native drivers, not some workaround that ultimately panders to the closed mentality of certain hardware suppliers. A closed source native Linux driver would be much better than no driver at all, a stepping stone on the road to the ultimate goal of open source drivers for all hardware.

Re:What about Broadcom? (2, Informative)

j0hndoe (677869) | more than 10 years ago | (#8522108)

Here's a source: [cemper.com]

In general the following chipsets are supported:

* Broadcom
* Intel PRO/Wireless Lan (Centrino)
* Atheros
* Admtek 8211

Good news, but... (3, Interesting)

biendamon (723952) | more than 10 years ago | (#8522021)

...I'm curious why it took so long for this to finally happen. Intel knew, for a long time, that there was extensive interest.

The Centrino is a good chipset, and Centrino-based laptops are fairly popular. Even without the wireless support, I've been happy using a Linux-based Centrino laptop for the last six months. The lack of wireless access was the one thing that had been sticking in my craw.

Now, I'll be able to unequivocally recommend these laptops to friends who use Linux. This will mean more sales for Intel. This, I would think, would be considered a Good Thing (tm). So why the wait?

OFF-TOPIC : Question about RAM (-1, Offtopic)

Anonymous Coward | more than 10 years ago | (#8522029)

Dude! Like, when did they stop making PC133 backwards compatible with PC100? I just bought a 128MB stick of PC133 for my laptop cause it was cheaper than the PC100. I get back home, put it in, and the computer refuses to boot! Frustrated, I go to PNY's website and lo and behold, it is NOT backwards compatible anymore! (My laptop runs a 100MHz FSB.)

So, what I want to know is WHEN DID THEY STOP MAKING IT BACKWARDS COMPATIBLE? Motherfuckers. Now I have to drive an hour just to exchange it for a MORE EXPENSIVE product that actually RUNS SLOWER! (Though my laptop obviously wouldn't run it at 133MHz, but still. I am mad.) Why don't they just say that it is not backwards compatible on the RAM packaging?!?!

Wireless extensions (2, Interesting)

fdawg (22521) | more than 10 years ago | (#8522041)

Anyone know if this implementation uses wireless extensions? Will these drivers use iwconfig and the rest of wireless tool or will you have to use some proprietary intel (probably binary only) tools? If it doesnt use wireless extensions, all of the neat scripts that come with stock distributions (debian, redhat, etc) wont work without some modification.
