The Battle for Wireless Network Drivers 163

Posted by timothy from the mind-the-nazgul dept.
An anonymous reader points out this Jem Matzan article "about the pain Linux and BSD programmers have in trying to obtain/write device drivers for various wireless cards," writing: This article also has a fairly detailed explanation of how wireless firmwares and drivers work. Two of the manufacturers are actively working with the FOSS community without requiring an NDA."

    Trying to develop wireless 802.11 interfaces for embedded platforms I agree that it is a total pain in a arse. I even knew people that I worked with before at broadcom and couldn't get them to kick down the Software API. We finally got a Philips BGW200 system working and that wasn't easy either since even after filling out NDAs we got messed around for a few months trying to get the right documentation.

    But now it does seem that Atmel is working with people, and accourding to the article so is raylink.

    What you can do to help is if you have choice, support these guys when you have to buy a wireless adapter even if it is a few bucks more.

HP sent me a replacement, I put it in last night, and after 4 hours use the SMART data reads 4 hours spin time and 54 hardware ECC hits. I have 5 year old Maxtors (with 1 year warranties) that don't have 54 ECC hits.

      No, lack of drivers is a product of Microsoft's dominance. Vendors didn't inherently go with Microsoft because they were Microsoft (Before they started being used on every desktop). Microsoft is now the dominant OS therefore vendors will release drivers especially for windows. Ever look at an AMD chip in the plastic? It says Designed for XP, same for 90% of the graphics cards made for PCs today. I think that the only way to have a level playing field with the drivers are for the vendors to open the code of the driver (NOT the firmware as some douchebags will want you to think) and/or give out some clear or semi-clear documentation on how the computer should interact with the device. OpenBSD has made leaps and bounds on doing this and stay committed. In fact they have excellent wireless support, especially since they love to be technically correct with code/security etc. Open source operating systems lack the back door business deals that make this easier to accomplish but it is a hell of a lot better than it was back in 1999.

    I remember reading awhile back that the reason that Intel had to have closed source firmware for their wireless drivers was because they said the FCC mandated that there was no way anyone could get the power output of their wireless cards. Does anyone know if this is true? If it does shouldn't we be pestering the FCC and not the companies since all they are dong is following the FCC's rules?

        They way I heard it, it was not the power output, but the frequency. Some wireless cards are apparently able to transmit on a wide range of frequencies, of which only some are allowed. If you have an open source driver for these cards, you can modify it so they use non-allowed frequencies.

          Likely this is true.

          In the case of IBM (now Lenovo), their laptops will not boot with a non-IBM-certified wireless mini-PCI card in the system. Their interpretation of the FCC regulations is that the complete laptop, with wireless card, is FCC-certified. Installing a different wireless card, even though it is a standard component, even from IBM itself, and has been FCC-certified by itself, in IBM's opinion, makes the entire laptop no longer certified. Therefore, they must prevent the now non-certified laptop from working so as to meet FCC compliance.

          It is a singular interpretation of the rules, as far as I know. There is a simple third-party fix to poke a byte to disable the check, so it can be worked around, but is still aggravating.

          While a bit off-topic to wireless drivers, this example shows that the rules are subject to such extreme interpretation. I can easily see the legal department of Intel, et al, deciding some rule would break FCC compliance and thus preventing open sourcing the driver or even making the specifications available.

      No, this is not true. The FCC regulations in question apply to the operators of the devices, not the manufacturers. Look at all the wireless devices that *do* have free drivers - they aren't illegal. If you edit the driver code to do something illegal with them, of course, you could get in trouble for that.

    • This is nothing more than a cop-out. They could lock these in the firmware and not expose that functionality in the driver. Instead, they put it all in the driver and use that as an excuse to not open-source the driver.

    Still I have the impression that lack of manufacturer willingness to publish documentation, is abused all too often to explain that there are no drivers for Linux, while the reality shows some other interesting facts. Here are some of my experiences I had with wireless in Linux:
    • First I bought a card based on fullmac prism54 chipset. It was known as one of the best supported chipsets in Linux, at the time the only 802.11g driver included in Linux kernel IIRC. It worked fine for basic operation yes, but it did not seem to support WPA. Prism54 development seems to be halted completely already for some time. People are developing the islsm driver which would also support freemac cards, but this is far from usable at the moment.
    • Intel Centrino ipw2200: had this in my laptop. Just installing firmware (which was as easy as adding PLF repository to my Mandriva system and running urpmi ipw2200-firmware) and it worked perfectly, WPA included!
    • Ralink rt2500 based PC card: I bought this again because I knew the manufacturer published documentation. Well, actually there are two drivers. The legacy driver, which should be somewhat stable, but which you cannot use when using multi-processor (dual core, etc), and the new driver which is beta and still unstable. Well, I tried both, but did not succeed in getting my wireless network to work.
    • Broadcom 43xx based PC card: was known at the time as one of the worst chipsets for Linux, because Broadcom was unwilling to publish documentation. Still bought it, because a new reverse engineering project started at that time. Today with kernel 2.6.19, this driver is included in Linux. And it works very good, WPA included. Yes, I had to install firmware by hand by means of bcm-fwcutter.
    So I'm arriving at the bizarre conclusion that for me, the best working wireless chipsets, are these from the category of manufacturers that are not very willing to work together with community. Still, there's a free driver, with only the firmware being proprietary and not freely distributable. Other drivers which should be in the recommended category, failed for me. Some reflections:
    • Good Linux support depends of much more than just the manufacturer publishing documentation. There should be an active community of developers: if that is lacking, even with good documentation, support will remain problematic.
    • Even without documentation it is possible to create good drivers by means of reverse engineering. If a card is popular enough and the right people at the right time start reverse engineering, then this could be a big success.
    • The presence of a proprietary, non-free driver could harm development of a free driver. For example take a look at the nvidia driver. Since a year, there's a reverse-engineering project to create a free dri-driver for nvidia, but it's not advancing at all. I guess lack of developer interest, because there's already the proprietary driver. Also look at ipw2945 driver: OpenBSD proved it can work without the the Intel binary-only daemon, but for Linux, nobody cared to reverse engineer it.
    • I bought one of those MSI-branded RT2500-based miniPCI cards for my Dell C640. It works quite well with Centos -- but only after compiling the driver myself, and I haven't been able to get it to work with a newer kernel quite yet. Otherwise, for stock Centos, this card worked great for me. I do wish I could figure out how to get the bluetooth working on it, but for $30 I was happy enough to drop the PCMCIA card.

      Then again, I haven't been able to figure out encryption, and all that fancy stuff yet. Works
