I am adding this topic to track this issue in the network forum. I have been struggling with getting my wireless card working with DSL 2.0 and 2.1 for a while and below is what I found.

Configuring my wireless card D-Link DWL-650 in DSL2.1b, I found what appears to be a syntax error in /usr/local/bin/prism2.sh. Is this a problem with the script?

Executing the line
wlanctl-ng "$1" lnxreq_wlansniff enable=false channel "$2"

bash-2.05b# wlanctl-ng "wlan0" lnxreq_wlansniff enable=false channel "6"
channel="argument_item_data_is_missing"
message=lnxreq_wlansniff
enable=false
channel=argument_item_data_is_missing
prismheader=no_value
wlanheader=no_value
keepwepflags=no_value
stripfcs=no_value
packet_trunc=no_value
resultcode=no_value

The channel is not assinged channel=argument_item_data_is_missing

Changing the line to channel="6" assigns the channel

bash-2.05b# wlanctl-ng "wlan0" lnxreq_wlansniff enable=false channel="6"
message=lnxreq_wlansniff
enable=false
channel=6
prismheader=no_value
wlanheader=no_value
keepwepflags=no_value
stripfcs=no_value
packet_trunc=no_value
resultcode=invalid_parameters
bash-2.05b#

You also notice the resultcode=invalid_parameters but I have no idea what that means.

The next line of the script
wlanctl-ng "$1" p2req_channel_info_results channel "$2

bash-2.05b# wlanctl-ng "wlan0" p2req_channel_info_results channel "6"
channel="argument_item_data_is_missing"
message=p2req_channel_info_results
channel=argument_item_data_is_missing
resultcode=no_value
avgnoiselevel=no_value
peaknoiselevel=no_value
bssactive=no_value
pcfactive=no_value
bash-2.05b#

Same error channel="argument_item_data_is_missing"

modifying the line

bash-2.05b# wlanctl-ng "wlan0" p2req_channel_info_results channel="6"
message=p2req_channel_info_results
channel=6
resultcode=not_supported
avgnoiselevel=no_value
peaknoiselevel=no_value
bssactive=no_value
pcfactive=no_value
bash-2.05b#

assigns the channel.

Addition note:

wlanctl-ng "$1" dot11req_mibset mibattribute=dot11WEPDefaultKey0="$4"

The format of the WEP must be like "12:34:56:78:90"

The results of the configuration:

bash-2.05b# ping damnsmalllinux.org
PING damnsmalllinux.org (65.254.46.177): 56 data bytes

Thanks dtf! My netgear USB wireless is working anyway, but couldn't get WEP to work before.

Any hope that this will fix the problem I reported earlier of having "no wireless card detected" despite pcmcia correctly identifying it and modules being loaded?
Although I get no error in dmesg when I modprobe either prism2_cs or hostap_cs for this card, both of which work very well for it in other machines.

I would suggest you try it and see if it helps. I simply cat'ed the script out and executed each line substituding the $1, $2 etc with the values. I could see from ifconfig that my card was associated with the interface wlan0 ($1), my network is setup to use channel 6 ($2), the SID is $3 and WEP is $4. Remember when enterring the WEP that you need the insert a colon ':' between every two hex numbers. Once configured I might of re-request dhcp (I don't remember).
