WLAN and DHCP troubles

[odrade]

Hello,

I am running knoppix off of CDROM and am attempting to get my Linksys WPC51AB wireless LAN card to connect to the network. The card is not detected by knoppix, but I can manually load the drivers, at which time the wlcardconfig utility detects it and will apply the settings I specify.

My problem is that I am not able to obtain an IP address from the DHCP server/Linksys Broadband Router on my network. If I manually configure an IP, I can ping the DHCP server, but if I just bring up the interface (or manually restart networking or manually restart pcmcia services), it does not grab an IP. When I do a iwconfig, it lists the router's proper MAC address as its Access Point so I know it sees it.

Stupid question-- how can I manually force my WLAN interface go out and search for an IP? On other linux distros I have used "dhcpcd" or "dhcclient" but cannot find either in knoppix.

Stupid question #2-- the wlanconfig utility finds the NIC fine once I load the drivers, however the netcardconfig utility still says it finds no supported cards. Is this normal when your Wifi is the only NIC, and if so, is there a utility to configure IP address settings for wifi cards?

Sorry for such a long post, thanks in advance...

Knoppix uses pump.

Do you mean "wlcardconfig"? I don't know what wlanconfig is.

Netcardconfig won't give you listings for wireless cards.

Besides wlcardconfig you can use iwconfig to configure your card.

Sorry, 'wlcardconfig' of course. Thanks for the info on pump! I have tried to use iwconfig to configure my settings, but for some reason it doesn't save any changes I make (maybe because I am running off of CDROM?) I have only been able to change wifi settings through wlcardconfig. Thnkas again for your response.
