D-Link
DWL-650+ under Linux HOWTO
[25/09/2003]
D-link has announced that Linux drivers
for the + generation of 802.11b cards that produces would be
published in early January 2003.
Such thing did not happened
as yet. The chip that ships with DWL-650+
is acx100 by Texas Instruments, and the driver we will use is the
acx100_pci from http://acx100.sourceforge.net
...
Due to the problems i find when i am looking for a
HOWTO to these setup i decided to make one when i
finish
configure the DWL-650+ under linux
Tested under :
I
use Redhat 9.0 , and Debian 3.0 , the Laptop is a DELL inspiron
8200, the wireless PCMCIA
card was a D-Link DWL-650+ (the + is
the key
) and the access point is a US Robotics 2249.
the steps taken
here is completly independient from the linux distro version
To
install this card on linux we need :
1. the kernel sources , I
will use 2.4.22
2. Wireless configuration tools
(http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html)
3.
the driver acx100_pci for linux , download it from CVS (or latest
version) on http://acx100.sourceforge.net
4. install CD of
DWL-650+ or windows files for this wireless card
Steps to make
the driver works:
1. Compile a new kernel with at least
:
CONFIG_EXPERIMENTAL=y
CONFIG_MODULES=y
CONFIG_KMOD=y
CONFIG_NET_RADIO=y
2. install tools from
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html
iwconfig,
iwspy and iwpriv must be installed from the deb or rpm package
.or if
you prefer from tarball sources.
3. Configure and compile acx100_pci drivers
# tar
xzvf acx100-0.1h.tar.gz on /root
put the next windows
files (or from DWL-650+ install CD) on the directory
acx100/firmware :
RADIO00.BIN
RADIO11.BIN
WBLAN.BIN
(it
may be on uppercase)
#make
4. install the driver :
copy recent compiled driver
acx100/src/acx100_pci.o to
/lib/modules/2.4.22/kernel/drivers/net
modify modules.conf
(add these 2 lines) :configure parameters to install modules
with insmod
alias wlan0 acx100_pci
options wlan0 debug=0xb
firmware_dir=/root/acx100/firmware
5. test the driver
# insmod acx100_pci
it must
show a little debug information about the driver and the
firmware .
Be sure the directory /root/acx100/firmware
contains the 3 files of Windows install or from
install
CD.
lsmod must show :
# lsmod
Module Size Used by
Not tainted
acx100_pci 181952 0
6.Configure parameters and network:
# ifconfig wlan0
192.168.0.10 netmask 255.255.255.0 up
# iwconfig wlan0 essid
myapessid mode managed channel 6 key off rate 22M
essid
is the ESSID name of my AP
mode must be managed for
wireless-ap or Ad-Hoc to use without AP
KEY off is to use
wireless without encryption
rate 22M is working for me , if
troubles use rate 11M
# ping 192.168.0.202
PING
192.168.0.202 (192.168.0.202): 1024 data bytes
1032 bytes
