First, I'm not saying that the research you have to do is either fun or easy, just that I'd rather put in the research pain at purchase time than at some later time that I don't control. Having said all that, to your point about the HP, HP's lack of specs is seriously annoying, but that machine AFAIK is a home-user model, and I haven't had a lot of good luck with that price-point from any vendor under any OS. They can't really expect business users to buy a machine without the card model. How could you manage a fleet of those things under any OS? However, if you were really dying to get that particular machine, they do say that you have an option for an "Intel wireless N mini card", which is very, very likely to work on any modern distro, so I'd feel quite comfortable buying that model as long as I was planning on running a recent Fedora or Ubuntu. Centos runs a bit behind the edge by design, so that's a trickier research project. You might want to look for a slightly older laptop in that case, or a business model with long term support where you can get an older card. HP does give the exact model of cards on their business class machines: http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/321957-321957-64295-3929941-3955552-4021356.html Which offers the Intel 5100. You can confirm that it's an in-kernel driver at: http://linuxwireless.org/en/users/Drivers Looking for an A/B/G/N Intel card, I clicked on iwlagn, which took me to: http://intellinuxwireless.org/ which confirms that, "After 2.6.26 the intree driver iwlagn also supports the new 5100BG, 5100ABG, 5100AGN, 5300AGN, 5350AGN, 5150AGN, 1000BGN, and 6000AGN series" so you should be good to go out of the box with pretty much any modern distro. Fedora has some pretty strict standards about what they will ship, which correspond closely to what I'm suggesting, so I find that anything supported under Fedora is likely to work reliably under any modern distro. There's more info at: http://fedoraproject.org/wiki/FAQ#Is_my_hardware_compatible_with_Fedora.3F Also, Fedora has an opt-in, anonymous hardware data reporting service called smolt, and you can see the results here of what people are actually running on: http://smolt.fedoraproject.org/ Smolt also confirms that a lot of people are running the 5100 out of the box under Fedora. For more manufacturers who provide specs, see also: http://www.dell.com/us/en/business/notebooks/laptop_latitude_e5500/pd.aspx?refid=laptop_latitude_e5500&s=bsd&cs=04 http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:category.details?current-catalog-id=12F0696583E04D86B9B79B0FEC01C087¤t-category-id=19C791A03AF24034A0011B825513BCED&tabname=TechSpecs#tabstart Like I said, it's not fun, interesting or easy, but it's a methodology that gets me a stable development machine year after year. Having fought with out-of-tree drivers on one card and witnessed the pain others around me have had with binary drivers, I'm pretty happy with it.
