Wireless LAN Devices For Linux?

Posted by Cliff on from the questions-revisited dept.

kemster writes "I've seen a few articles on different Wireless ethernet devices which are supported under Linux, but I'd like to know what people's experiences with them are. I'd like to get a wireless ethernet card for my laptop, and Linux support is a must, but I'd also like something that isn't too expensive and has decent range and speed. Does anyone have any suggestions? What have other people used? I'd love any suggestions and/or links people have to products." We've discussed this issue over a year ago and the market for wireless networks has grown dramatically since then. Has the intervening time changed anything when it comes to wireles options for Linux?

  1. Lucent Wavelan/IEEE by chris.dag · · Score: 3
    The lucent 802.11b cards (sold as 'Orinoco' for home/SOHO users) seem to have the largest amount of Linux suport when it comes to drivers and HOWTO documents. They are not cheap though.

    I bought the RG-1000 gateway and an Orinoco silver card a few days ago and after a bit of fiddling had my linux notebook up and running at 11mbs. The windows client software was better at things like measuring signal strength & noise with a shiny little GUI. Range and performance seem to be very good. One problem with the RG gatway product is that it requires a Windoes system to set up the initial configuration.

    URL would be www.wavelan.com.

    Another option depending on driver ability would be the 802.11b stuff from Compaq. I noticed that they are selling their gateway software CD for $125 which means you can build your own access point on an existing system for the cost of the software and a PCI wireless card.

  2. My Research So Far (Includes Access Points) by rjsjr · · Score: 5

    I'm looking around at both cards and access points with linux compatibility, here's what I've found. It seems 802.11b wireless networking is definitely getting cheaper and a number of decent products have been showing up at half previous typical prices. D-Link and SMC are leading the low end of the market with decent quality products and at least stated linux support and Orinico/Lucent and Aironet/Cisco are the leaders if you want a more robust feature set for your access point (in particular, support for external antennas).

    PCMCIA Cards

    • For cards, the cheapest decent card I've been able to find is the D-Link DWL-650, which can be had for around $120 from a reputable web retailer. However, while D-Link claims linux support in their FAQ, I can't find a driver to download from their FTP and a google search didn't reveal anything elsewhere. Haven't really looked hard, but dubious with that in mind. I should also note that the D-Link claims shorter ranges (1,000 ft. v. 1,500) than most of the other cards/access points, but I suspect that has little real world relevance.
    • The next best option seems to be the SMC 2632W, which has linux drivers available for download (haven't tried them out, though). It tends to run about $20-30 more from similar sources, but looks like a good product and appears to have better support.
    • After that, its a tossup in the $200-300 range from the major networking manufacturers. I don't see a clear advantage of any of them over the cheaper products, but haven't looked at power consumption levels and comparison tests from major publications aren't new enough to include these products (that I've seen).

    Access Points

    For those who are also interested in what's going on with access points, including linux support on configuration:

    • Currently thinking about the D-Link DWL-1000AP which goes for a little under $300 if you look around for a good web retailer. Main downside is a lack of linux support in configuration software (needed to set static IPs by address), though this isn't a big deal for me as I run a mixed network. Too bad it doesn't have a nice mini-web server for management like my HP printer (LaserJet 2100NT). They list telnet support in the data sheet, but its not clear to me if you can telnet to the hub to make changes ...
    • Another potentially good and cheap model is the SMC 2652W, but supply seems to be limited on this right now. Again, no linux configuration utilities, but you can console connect via RS-232, which the D-Link doesn't have. SMC has linux drivers available for its PCMCIA card now.

    Unfortunately, neither of these have the antenna adapter that some of the Lucent Orinoco (formerly WaveLAN) access points feature, but they also don't cost $700+ (its more for the 2 radio model). Not really much of an issue for household use (unless you have a multilevel apartment with concrete flooring), but if you want to cover multiple houses, roam around farther outdoors, or set up a free wireless LAN (slashdot discussion) for people in the area [SF for me] (I could run a really popular access point, living across the street from Moscone). There are a number of other good access points from Cisco/Aironet, HP, Intel, etc., but these are the standouts for price/performance in my research.
