How to enable wireless device (D510) in Ubuntu 9.04?

Hello,
I recently upgraded my Dell D510 laptop to ubuntu 9.04. Everything seems to be working, and for the first time ever (in my experience), it detected the wireless network card and setup a driver by itself!

The problem I am having, is the fact that I CANNOT get the card to be enabled. In otherwords, when I use the NetworkManager and tell it to use my wireless network with ssid linksys, with a wep key, it simply does nothing. So I ran a command to see what was going on:

sudo lshw -c network

I got this:

I googled around and found a procedure that looked promising yet did nothing:

sudo modprobe -r b43 b44 ssb wlan
sudo modprobe ieee80211_crypt_tkip
sudo modprobe wlan0
sudo modprobe b43
sudo /etc/init.d/network restart

the result of this, is that network manager, simply pops up a window saying the device is disconnected.

Finally, I checked the ubuntuforums, and found another procedure which also did nothing:

I added a line to my /etc/network/interfaces file that read iface wlan0 inet dhcp

I then ran the following commands:

sudo iwconfig wlan0 essid $ESSID key $KEY.
sudo ifup wlan0

This also did nothing but have networkmanager tell me again that the wireless was disconnected.

Can anyone tell me how to fix this issue. Its REALLY annoying, and without the wireless internet my laptop is more or less pointless.

Worth 500 points.
