Wireless WMP54G v4.1 dhclient Cannot Get IP

[binarybob0001]

I'm using Slackware 10.1 with kernel 2.6.16.9. I have installed rt61 driver to use with the card.
When I turn on the computer, the rt61 driver is automatically loaded though I'm not sure how.
I type ifconfig ra0 inet to turn on the TCP/IP interface.
I type ifconfig ra0 up set it up for broadcasting.
I then use iwconfig to set the network with iwconfig ra0 essid linksys.
After doing this, I type dhclient ra0. It says, "ra0: not found" and then a long message about how if I didn't get the software from isc, I should go there and read the README before I complain bla bla bla.
When I check the status of the device, I get this information.

Under iwconfig ra0

Under ifconfig ra0

From all this, it seems the device should be ready to get an IP, but dhclient says ra0 doesn't exist. In one way it's right because I can't find a device by that name in /dev. How is this possible? Thanks.

what does this return:

dmesg | grep ra0

Hello binarybob,
I couldn't help but notice the similarities between this thread and the thread that I posted above. So I was wondering which driver were you using, the RT61 driver from the Ralink website, or the one from the Serialmonkey web site???
