802.11b Wireless Ethernet PCI cards?
Chuck nc8q Gelm
Sorry for the crosspost, but D-Link suggested linux-newbie,
yet I want to use this device in FCC part 97.
I considering using D-Link DWL-520 cards.
What drivers are needed to operate 802.11b wireless ethernet
devices with linux (kernel 2.2.x or 2.4.x) ? I see references
to PCMCIA cards, but not PCI cards.
My concept is an open LAN using directional antennas and
a 'water tower' as a passive reflector. I've seen articles
about these devices spanning 20+ miles LOS. Perhaps if hosts
are within 5 miles LOS of a water tower, they could communicate.
The thought of $100(USD) 11 Megabit radio modems has my interest!

Same... Almost... Most of what I have played with are just
the same PCMCIA cards with a PCI or ISA adapter. I've seen one (CISCO)
where the external antenna plugged into the board and it used a special
PCMCIA card. Another (Lucent) had the external antenna plug straight into
a stock RoamAbout card. What you are really asking for are the drivers
for the PCMCIA to PCI card and they are there too... I'm currently
running the RoamAbout in my gateway. I've got an 11dB Omni in the
attic that works the neighboorhood pretty good.

We've got a parabolic on top of our office building (5 story)
and been able to work distances significantly further. LOS, of
course... :-)

Unlike many of the cards that are basically a PCMCIA card with an
adaptor, this is actually a "native" PCI card. One of its advantages
is a removable reverse SMA connector for the antenna, so it would
presumably be fairly easy to put an extension antenna on for greater
range.
This card has the Prism2.5 chipset, which is the PCI variant on the
Prism2 chipset used in many PCMCIA cards. The linux driver for this
card (and other Prism2/2.5 cards) is available from
www.linux-wlan.org. The site provides three drivers for cards based on
this chipset; one for straight PCMCIA, one for PCMCIA cards in a PCI
adaptor, and one for native PCI cards.
A word of caution if you are using older hardware; the DWL-520 card,
like many other wireless PCI cards, will ONLY work with a PCI 2.2
bios, which as far as I can gather probably means a Pentium II or
higher processor.
Another card you may want to look at is the Lucent Orinoco card, which
I understand is made in both a PCI and an ISA version. Again, the PCI
version only works in newer hardware, whereas the ISA will even work
in that old 386 you have lying around... see
