      OS zealotry is just (hopefully) a stage in the growth of a user. it's when they realize the OS is great for their use, they imagine how many other great uses it could have for them, and then think everyone must use this because it is so great for me. hopefully they realize eventually that other people use things that are great for themselves, and changing would be detrimental to what they want to accomplish. Eventually the zealot will come to terms with diversity and no longer be a zealot. the problem is there will always be zealots, but the people who are zealots may change.

      I feel your pain. The problem you will run into is that even if you get a D-Link, Linksys, or Netgear, some of them may use the same chipset. I tried the D-Link first because it was cheap. It used the Prism2 chipset. But after reading every bit of documentation, and trying it as both a module and in the kernel under about 10 configuations I gave up. It seems like getting these cards to work is hit or miss for a lot of people based on all the posts I read. And believe me I read a bunch.

      Then I tried a Linksys that I use on my work XP laptop. No dice there. I forget the chipset on that one, but I had the Linksys WPC11 v4 which apparently has little or no support on Linux.

      So finally I decided to just bite the bullet and get a Cisco Aironet 350. If you buy these new, they are over $100. But if you go to Ebay, you can get one for around $50. All you do is compile the support in the kernel and it works like a champ. I have set it up successfully on both Debian and Gentoo.

      So Cisco is the easy way to go if you can get a good deal. I would avoid the Linksys card I tried, but apparently versions prior to v4 work better. You can give the D-Link or Netgear a shot with the Prism2 chipset, but you may have to work at it a while to get it working.

      Hope that helps.

Too bad running Wine pushes the temperature up and up until the laptop performs an emergency temperature shutdown in a last desperate act of self preservation. But I digress...

        I now have a Cisco Aironet 350 from work, and it works with the driver built-in to the kernel.

        If I had to buy another card, I'd still get a PrismII or Prism54 because of price.

          stable -worked out the box in SuSE 9.1

          My work laptop has an ActionTec mini-PCI card and that was trouble indeed. It kept on locking on a session (RH.9), and now that I am running WinXP SP2 on the laptop, it wont hibernate while the card is in use.

          So: open source -incomplete drivers you'd have to fix by hand. Closed source -shit drivers you cant fix. Either way -no out-the-box networking.
        • What was your Prism problem? The only thing not there on Fedora Core 2 was the firmware, which you had to extract from the Windows driver disk and copy into a particular place. The thing is that in my case, a Netgear WG511 card was more stable under FC2 Linux than Windows.

            • I don't know about the D-link, but with my Netgear, FC2 booted with the Prism module loaded. You do need the firmware but all the usual toys are there (iwconfig, etc). Loading the firmware doesn't happen automatically during boot, but it will work after boot though (known FC2 net startup issue). There are some other minor problems with FC2's network conmfiguration script but these can be fixed by a direct edit to a couple of configuration files.

      Well, the answer is don't get cutting-edge hardware. You can get excellent, servicable wireless 802.11b hardware from several years ago, and that is the golden era for open drivers. Something like a Cisco Aironet 352 is perfect, with excellent drivers and support from all layers of the operating system (linux, bsd, win32, macos, ...). Not surprisingly this is also the interviewee's recommended hardware.

      As far as headaches, I think you'll find more headaches in the peripheral support infrastructure than in the wireless hardware and drivers. If you are going to use PCMCIA/PC Card wireless adapters I think you'll discover the Linux PCMCIA drivers have a habit of panicking. With any hardware you'll need to do a lot of manual configuration hacking before your computer will perform useful functions like automatically roaming to available SSIDs (something windows and mac os do automatically). You'll be installing packages and editing /etc files for the next month, but eventually you'll have something that works 62% of the time.

    About a year and a half ago, I bought me one of those linksys wireless cards for an older (400MHz PC) running RH7.3 or something like that. For the fun of it, I decided I'd ask the salesfolk at Best Buy whether it was compatible with Linux. The answer I got was that it would be difficult to find drivers for it, and that to save me the grief, he recommended I get a LAN-Bridge instead.

    I ignored the advice and bought the card anyway. (Of course I had done some research beforehand...enough to know it possibly worked, anyway) I got it running with the wlan-ng drivers.

    Later on when I had more money, I decided to get me a laptop. Again, did my homework to see what would and wouldn't work. Again, a trip to best buy encountered a tech/sales guy -- whom I asked the question "will it run Linux?" After spouting off a few acronyms of certifications he has, he proceeds to tell me that Bill Gates has bought Linux and that we won't even be talking about it a year from now (he's got about 2 months left of that year...better act fast!) Then if I wanted to run a linux server on a laptop (no I don't want to run a server...just a desktop -- 'um, same thing') -- that it would be really slow. The only hope I have of running it comfortably would be on an Alienware system.

    "So why don't you want to run XP?" "It's got a large system requirement, it has serious security issues, and overall I can't say I like it." "Have you looked into using XP Pro?" "Um, I already don't want to pay for the OS, you're recommending I pay MORE instead?" "Well, XP Pro isn't going to cost you that much more..." "Thank you for your time. I think I'm going to go home and rethink my strategy."

    Went home thinking "jackass" and proceeded to get a Dell...which I'm using to write this post...now on a machine running Mandrake 10CE...with all the functionality I need.

    Zealotry or ignorance? I'm not sure. To this day I smile whenever I go into a Best Buy -- thinking I should pick up a piece of hardware and ask whether it works with Linux just for the stories they may give me.

      You know, you can get your own cable modem for $25/mo and hack into all the systems you possibly can from the comfort of your own couch. Anonyminity is easy enough. If you really do want to hide behind a wireless AP, you're going to drive to the local universtiy and get many mbit/sec. I highly doubt you're going to park outside my house and use my tiny

  • OS Zealotry (Score:5, Insightful)

    OS zealotry is doing a disservice to our community, because if you force somebody into something against his will, you run the risk of creating negative experiences.

    The problem is not so much that it *forces* anybody to use a system like Linux (because it's pretty much impossible for an opinion to be that powerful in the face of economic and political reality), but that it serves to blind people to the potential pitfalls that await, thus leading them to make a wrong decision for their situation. NO system is perfect (even Linux and *gasp*! Mac OS X). ALL have pitfalls depending on what you're using your computer for. In many cases, Windows *is* the best choice, although improvements in KDE and Gnome are making Windows a less obvious choice. And of course, arguing in favour of a system (or a methodology like open-source) is perfectly acceptable, as long as both sides are rational and can concede that the other side has positive attributes as well. Thus, both sides learn from the other and take what they've learned to improve themselves. Thus, honest evaluation leads to progress and growth, which is one of the fundamental tenets of capitalism, the free market, and all that... Of course, the ability to meet halfway is now called "appeasement" and is labeled as a "liberal" trait, which is apparently synonymous with "evil" or "corrupt". Zealotry exists in politics of all types, and is a great temptation, since it's so easy to believe that the world is black and white, good vs. evil, and that there is nothing to learn from the other side and that their arguments are all irrational and unfounded. Zealotry is a glass ceiling on self-improvement.

    Zealotry in any form is inherently dishonest because zealots consciously or unconsciously hide the faults of their beloved systems while simultaneously proclaiming their greatness. This does lead to bad experiences (and I'm talking from experience!).

    The UPSIDE of being a Linux zealot as opposed to a Windows or Mac zealot is that because the system is very open, any roadblocks you may encounter are likely soon to be fixed, or are fixable if you know a programmer who accepts payment in beer and pizza (which is all of them). I've hit roadblocks in Mac OS X that have no solution, and none seems to be coming... and [zealotry on] Windows itself *IS* a roadblock! [zeatotry off]

  • Future of wireless networking (Score:5, Informative)

    As hinted at in this interview, the future of wireless networking revolves around many variations on a few core themes: diversity, versatility, and scalability [peertech.org].

    Diversity is accomplished through MIMO and other technologies like beam steering to provide a robust communication channel between wireless devices.

    Versatility comes with open source firmware / drivers and software defined radios. There is no way manufacturers can foretell all of the desirable uses and functionality consumers want in their products. The most useful systems will be those that are versatile and can adapt to new protocols, encodings, etc.

    Scalability can be achieved through robust ad-hoc routing protocols and decentralized security methods to produce a system that scales easily as participating nodes join and part the network without complicated provisioning or a reliance on centralized and limited backhaul or access point functionality.

    There is still a lot of interesting work to be done in these areas, but the real fun starts in the applications that will utilize these new ad-hoc networking infrastructures.
  • Amazingly, after a few hours of tinkering, I just got onto slashdot using a Broadcom BCM5406 g card. Guess what the first article I read is.

    Broadcom won't release drivers or specs for their wireless chipset and prevent any OEMs who use thier chipset from doing so. So there are only really two choices, other than throwing their hardware in the trash, or using Windows, and those are Linuxxant WLAN Driverloader [linuxant.com] or open source NdisWrapper [sourceforge.net].

    I chose NdisWrapper because it is OS and I did not have to pay
  • Are there any USB 802.11 devices that simply work, without kernel recompiling or similar extra work? :)

    It would be great to add this to the list of Things Good To Demo On Random Laptops With Knoppix! Actually, what would be even better to demonstrate is the USB WiFi+kitchen scoop long-distance antenna [slashdot.org] :)

    Shoebox computers in particular tend to have precious PCI slots, and (unless you add an semi-expensive* adaptor) no PCMCIA slots, so this would be a great way to add wireless networking to them.

  • Last time i checked, my wireless router didnt really care what OS was on the machines attached to it..

  • I just received my ActionTec GT-701(?) last week, and find that it's running a linux kernel. It's got 802.11g, a single 10/100 port, functions as a USB NIC, and also happens to be my new DSL modem.
    If anyone's curious, reply to this and I'll log into it again and get the kernel version specifics.
