How do I install BCM4312 wireless drivers?
I recently installed Ubuntu 11.04 to dual-boot with the Windows XP in my Dell™ Inspiron E1505 laptop. Unfortunately, I can only connect to our wireless network while in Windows. In Ubuntu, I can't go online unless I physically connect it to our cable modem.
I am still a beginner, here is what I was able to get from searching online. Here is my hardware:

I also checked the status of Network Manager:
kalayaan001@Kalayaan-MM061:~$ nm-applet
An instance of nm-applet is already running.
** (nm-applet:1727): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager.
How can we initialize the D-Bus manager?
kalayaan001@Kalayaan-MM061:~$ nm-tool
NetworkManager Tool
State: disconnected
- Device: eth0 -----------------------------------------------------------------
Type: Wired
Driver: b44
State: unavailable
Default: no
HW Address: 00:19:B9:85:01:CA
Capabilities:
Carrier Detect: yes
Speed: 10 Mb/s
Wired Properties
Carrier: off
It seems that all it can detect are the devices of wired Internet. How can we make it recognize the devices for wireless?
I then checked for blocks, but found none.
kalayaan001@Kalayaan-MM061:~$ rfkill list
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
So, I thought it to be a driver problem and, surely enough, I found in "Additional Drivers" that it was lacking in a Broadcom® STA wireless driver. Unfortunately, getting the driver didn't fix it, either. It still cannot detect anything.
How is this fixed?

Thank you for your time.

Response to sagarchalise:
I installed all 4 entries under the keyword "bcm4311": firmware-b43-installer, bcmwl-kernel-source, broadcom-sta-common, and broadcom-sta-source. (There is even b43-fwcutter, though that appears for the broader keywork "bcm".) The problems is still there.
Additional Drivers reports: "This driver is activated and currently in use."
Here is ifconfig:
kalayaan001@Kalayaan-MM061:~$ ifconfig

Here is iwconfig:
kalayaan001@Kalayaan-MM061:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
How can I get these extensions?
The results of 2 codes seem to have changed in the process:
1) nm-tool
kalayaan001@Kalayaan-MM061:~$ nm-tool
NetworkManager Tool
Everything after "Tool" is gone.
2) sudo lshw -C network Before:
kalayaan001@Kalayaan-MM061:~$ sudo lshw -C network

In Ubuntu code, what does"UNCLAIMED" mean?
I tried the code suggested in the website. Unfortunately, there was no effect. I will try again in the morning (It's past bedtime in my timezone. So, I'm just about to retire to bed.)
Any more proposals?
Thanks again for your time. Your reply is most appreciated.
Take care,
