Wireless connection troubles

[Nagantman]

Hi, a few days back after some struggling. I managed to install Ubuntu 11.10 on my 2010 13' Macbook pro 7,1. I'm very new to Linux and entering commands through Terminal. I don't know how to search for wireless networks so, I added it into the wireless connections. But I don't know how to get my BSSID/SSID or MAC device number, I think it's called. So I tried getting onto the internet with an Ethernet cable. When I plugged it in it still wouldn't make a connection. Then I had noticed it said firmware missing by all the connection/wireless information. I have already used a looootttt of google to no avail . Any help with this problem will be greatly appreciated thank you in advance

Let's see what kind of wireless card you have and we'll find some firmware. Please open a terminal and do:

lspci -nn | grep 0280

That pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

You may need the linux compatible driver for your network device. You could try a google search
using your device name driver linux

That's not what I asked for. Please see post #2.

After putting in that command line

lspci -nn | grep 0280

this is what came up in Terminal- 02:00.0 Network controller [0290]: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01). Bear with me like I said I am new to this.

Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b]

Your device needs:

sudo apt-get install bcmwl-kernel-source

Do you have a working ethernet connection? If so and if you can get connected, this will be quick and easy. If not, we have a big job ahead of us.

If it's not working, let's try to see why:

lspci -nn | grep 0200

I tried an Ethernet cable the other night and it didn't work.

lspci -nn | grep 0200

03:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5764M Gigabit Ethernet PCIe [14e4:1684] (rev 10)
