no wireless internet connection

I installed Mandriva 2006. It detected my USB wireless adapter. I entered ESSID and Key in MC. But I still got no connection. Here is the output of iwconfig and ifconfig:

output of iwconfig:

Can anyone help me?

You need to run DHCP in order for your machine to receive a valid IP address. You seem to be on the right track. Try typing "dhclient wlan0". I use dhclient, but I think there are other DHCP commands out there. After that, you should be connected (assuming the key is correct and everything).

Doesn't look like your wireless card picked up your AP for sure, doesn't have a MAC address for it. Do you have an arp entry for it? (type arp -a). Do you have a default gateway listed in netstat -ar? Try to ping (or whatever your access point's address is) and check the arp table again. See if anything changed.

This was the easy part of my configuration. I'm not too much help. Once I got linux to play nice with the wireless adapter (which wasn't easy for me), it found the AP fine. DHCP does seem to be not happening here. Try searching your /var/log/messages file for anything having to do with that and pasting it up here for someone to interpret. Here's mine, look for something similar. You didn't at any point configure your computer to not get a dynamic IP address did you? My installation used a dhcp client by default.

You also have the interface aliased, that is like you had 2 wlan0.

You can try kwifimanager and drakconf to configure the interface wlan
Poste route -n as well
Also think you have a dhcp problem
No expert at this game, you may want to ask your post to be
moved to networking if you cannot solve the issue in ~2 weeks
with other contributors to the thread

As a side note, welcome to LQ
It would help if you were precise on the USB device used
and posted relevant bits of the /var/log/syslog that
proove that the right driver is used for the card
