LinuxQuestions.org - Belkin F5D7050 v3 rt73 USB wifi on Debian, can't connect to router

i am using debian squeeze (2.6.32-5-686) on a via mini itx. i am trying to get the wifi up and working with a Belkin Components F5D7050 Wireless G Adapter v3000 [Ralink RT2571W]. i am using the rt73 driver because that is what the chipset indicates i should use.

i followed http://wiki.debian.org/WiFi/rt73 to get the wifi usb working. however, i cannot connect to the wireless router. i use rausb0.

the symptoms:

everything seems to be working ok but for a couple of key things. i did the install using the debian wifi wiki, so i think that the driver is properly installed and deconflicted. i updated the vi etc/network/interfaces just as is indicated, but when i iwconfig it does not show the essid that i put into the etc/network/interfaces, nor that i have WPA (it says Security mode:open). not only that, but when i ifconfig, it does not even list an inet address. further indication, cat /var/log/syslog indicates no IPv6 routers present. using iwlist scan, i can see the router, and ifconfig indicates packets are going up and down. when i ifdown and ifup, it just sits there and says "DHCPDISCOVER on rausb0 to 255.255.255.255 port 67 interval 12" until it tells me it received no DHCPOFFERS and is going to sleep. also, the little LED on the Belkin device is intermittently blinking like its browsing reddit or something.

What am i missing? help?

here are the outputs from some key commands. i have info from lsusb, lsmod, dmesg, cat /var/log/syslog, ifconfig, iwconfig, iwlist scan, and vi etc/network/interfaces.
