cat /etc/network/interfaces

and heres what i got:
ddub@ddub-laptop:~$ iwconfig

If you have your wired connection working, go into System->Administration->Hardware Drivers and enable the Broadcom b43 option. It will download a firmware file that is needed to help make your wireless card work.

If it does not work, just come back and let us know what happened and we can try some other things. Your card is able to use the b43, Broadcom STA(wl), and ndiswrapper for wireless modules so you do have some options. The b43 option is the best one because you have a Broadcom wired ethernet card so the other options will require you to use a workaround to make your wired and wireless cards to work.

That worked perfect! OMG after reading all of these different posts the last few days and nothing worked. a simple enable click made it work i cant believe it. thank you!!! browsing firefox looks so nice on here!:KS;)

Hello! I have this same computer but the above did not work (there is no option in hardware drivers for broadcom). To make things more interesting, the wired connection does not work either. Has anyone run into this problem?

Have you tried the following:

sudo modprobe -r b43 b44 ssb wl ndiswrapper
sudo modprobe b44
sudo ifconfig eth0 up
sudo dhclient eth0
Hopefully, that will get your wired card started. If it does, please post the results of:

lshw -C network
lsmod|grep -e b43 -e wl

Upon "sudo dhclient eth0" I receive

If you go into the Terminal and do the following:

lsmod|grep b44does it show the b44 and ssb modules?

It shows both. Here is the full output:

Does dmesg|grep eth show anything? Also, have you installed the firmware for the b43 module?

dmesg|grep eth gives

I'm pretty sure the firmware is not installed, unless 8.10 has it pre-loaded. The documentation I've found says I need to explicity get it. The problem there is that I can't download it. I do have a thumb drive, though (which is how I'm transferring the terminal output). I'm used to Gentoo's portage, so I'm not sure how to manually install something using apt-get.

Thanks for all your replies, by the way :)

You can try this link to see if you can get the firmware installed:
http://ubuntuforums.org/showpost.php?p=6077792&postcount=72

You might also check:

dmesg|grep b44It is showing that it is powering down for some reason. The info from the b44 module might provide more information.

This is dmesg|grep b44

Unfortunately I'm not quite sure what it's trying to tell me. I'll try the link and see if I can get the firmware installed.

Looks like success! Thank you :)

Your instructions in the link you provided worked perfectly.
