WEP configuration for DWL520 in Linux
 

Hi

I am using a DWL520 wireless card on my RedHat Linux machine to connect to the wlan provided by my apt. They have given me an SSID and a WEP key.

I downloaded the prism2_pci driver from linux-wlan.org and built/installed it. I don't know how to configure the /etc/wlan/wlancfg-SSID file to pick up the WEP key. please help.

Further, the help file says that I should use

>ifconfig wlan0 <ip addr> netmask <> broadcast <>

How do I set this to use DHCP and automatically pick up the IP..

thanks,
krishna

just edit the /etc/wlan/wlancfg-SSID file like the following if you have 128bit WEP, then do a /etc/init.d/network restart

#=======WEP===========================================
# [Dis/En]able WEP. Settings only matter if PrivacyInvoked is true
lnxreq_hostWEPEncrypt=true # true|false
lnxreq_hostWEPDecrypt=true # true|false
dot11PrivacyInvoked=true # true|false
dot11WEPDefaultKeyID=0 # 0|1|2|3
dot11ExcludeUnencrypted=true # true|false, in AP this means WEP is required.

# If PRIV_GENSTR is not empty, use PRIV_GENTSTR to generate
# keys (just a convenience)
PRIV_GENERATOR=/sbin/nwepgen # nwepgen, Neesus compatible
PRIV_KEY128=true # keylength to generate
PRIV_GENSTR=""

# or set them explicitly. Set genstr or keys, not both.
dot11WEPDefaultKey0=****** YOUR WEP KEY HERE *********

# format: xx:xx:xx:xx:xx or
dot11WEPDefaultKey1= # xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
dot11WEPDefaultKey2= # e.g. 01:20:03:40:05 or
dot11WEPDefaultKey3= # 01:02:03:04:05:06:07:08:09:0a:0b:0c:0d
#=======SELECT STATION MODE===================
IS_ADHOC=n # y|n, y - adhoc, n - infrastructure

#======= INFRASTRUCTURE STATION ===================
# What kind of authentication?
AuthType="sharedkey" # opensystem | sharedkey (requires WEP)

#======= ADHOC STATION ============================
BCNINT=100 # Beacon interval (in Kus)
CHANNEL=6 # DS channel for BSS (1-14, depends
# on regulatory domain)
BASICRATES="2 4" # Rates for mgmt&ctl frames (in 500Kb/s)
OPRATES="2 4 11 22" # Supported rates in BSS (in 500Kb/s)

Thanks a lot Ray..

I found out that my wireless LAN has a 64-bit encryption and they have give me a 10 character hex key for it..

should i change

PRIV_KEY128=true

to

PRIV_KEY64=true

and enter the key

dot11WEPDefaultKey1= AA:BB:CC:DD:EE

i will try the above mentioned steps and see.
thanks again for the help..
