Driver for a 3Com 3CRWE62092A X-Jack
PCMCIA wireless card for Linux 2.6.x kernel
The driver has been designed for 11 Mbps Wireless LAN PC Card (1148)
3Com 3CRWE62092A Wireless LAN PC Card, but should work with all poldhu
based cards with minor modifications.
The driver now supports changing SSID, Airlock(TM), WEP encryption and
Ad-Hoc (IBSS) mode. This is configured using the wireless-tools.
As of version 0.2.13, it also supports Active Probing on the 3Com
cards, which is needed to authenticate to certain base stations.
Check the project's download
section at sourceforge.net/projects/poldhu.
The original version 0.2.x of the poldhu pcmcia driver was written for
kernels 2.4.x by No Wires Needed (check http://www.xs4all.nl/~bvermeul/swallow/).
It was then re-written to support early 2.6.x kernels and released as
version 0.3.1 on Mon Dec 21 12:00:00 CET 2003 by firstname.lastname@example.org.
Since I happen to have access to this pcmcia card, I tried to use it on
2.6.9. Of course,
the 0.3.1 driver would not build. My e-mails to the original developer
So one day I have decided to do the port myself - taking as an example
some other wireless
driver and cut-and-pasted the driver's logic.
Unfortunately I do not have any information
about the chipset, logic diagrams e.t.c.
So if you have more info about this hardware, or notice a problem -
please let me know...
Still, it is a cool card, and the driver works for me...
PS. I do not know what exactly happens with the hardware when the
antenna is pressed in.
Somehow parts of the hardware are disabled or powered down. As a result
the card init fails.
Basically never use this option as the results are unpredictable (will
the card jam or come up?)
PPS. There is a similar 3Com 3CRSHPW196 X-Jack (greenish label) card
is using ATMEL
This poldhu driver does not support the ATMEL card.
PPPS. The 3Com WinXX driver can be found at 3Com
