Help! Totally unable to connect to wifi with acer netbook

[jesseber]

I have an Acer Aspire One netbook that I have installed Ubuntu 11.04 onto and I am unable to connect to my wireless network because of "missing firmware". I'm completely new to Linux as a whole so I'm not too savy with it in general, but I've searched for hours and hours and I've tried every single workaround, patch, and fix to no avail so I figured I'd try to get some more personal help here.

Can anyone get me online?

Let's have a look at these results from a terminal:

lspci -nn | grep 0280
rfkill list all

Thanks.

Can you temporarily get a wired ethernet connection? Please do:

sudo apt-get install firmware-b43-lpphy-installer

After it completes, detach the ethernet cable, reboot and tell us how it's working.

Plugged directly in and it still won't connect =/ The wifi symbol reads and reads and then disconnects.

What?? Network Manager is designed to disallow a wireless connection if you have wired. What is the behavior with the ethernet detached? Do you see your network? Can you click it and be challenged for your WPA2 encryption key?

Unplugged, when I click the little icon it only brings a drop down menu with no network choices because the "device is not ready (firmware missing)". When I plug in the ethernet, the little wifi icon pulsates like it's trying to connect but ultimately fails. I have a phone, laptop, xbox, and desktop in the house that can all connect to the signal fine. It's just this netbook..

So you have no ethernet connection with wich to download the firmware. Let's troubleshoot the ethernet. Please post:

lspci -nn | grep 0200
ifconfig

Thanks.

You have a healthy looking ethernet interface, eth0 and it's been busy:

RX bytes:165893 (165.8 KB) TX bytes:7684 (7.6 KB)

Plug it in and let's see what's going on under the hood:

dmesg | grep atl
sudo cat /var/log/syslog | grep etwork | tail -n 20

The highlighted part is lower-case for ATL.
