LinuxQuestions.org - Mandrake 10 and wifi but no internet

Hello,

I'm a windows user trying to get off windows and installed mandrake
10 download version on my thinkpad.
Install went fine. My first order of business is to get my wifi card working.
I've got a Netgear wg511. I've download and installed the lastest
firmware for the card, and it appears I'm almost there in getting it to work.
I know this card works on this laptop, as I've been successfully able to
get this machine to dual boot Mandrake 10 and Windows 2000. The card
works fine in Windows, and I'm able to connect to one of two networks near
me.
In Mandrake it appears I'm getting an IP address (I think) but using the browser I can't browse anything, and I can't ping anything.
What else do I do? I'm really new to all this, and I've scoured the newsgroups for hints on what I'm missing, with no luck.

What else do I do or try to browse the internet?

Here is the output if Ifconfig and dhclient:
