I just installed Ubuntu and there is firmware missing that prevents me from using a wireless internet connection
I installed Ubuntu on my laptop earlier today and have not been able to connect to the internet. While checking through any way I could make a connection, I noticed that under the internet symbol under where it says Wireless Networks, it says "device not ready (firmware missing)". As someone very inexperienced with tech issues, my first thought is that something didn't install right, or that there exists a patch to possibly remedy this problem. Can anyone confirm this for me?

We need some info in order to give you any help.
Did you install Ubuntu with wubi, or on a partition or usb device?
Please start a terminal, run the following commands, and paste the output back here.
lsb_release -a
lshw -C network
Firmware is possibly not present by default because it is vendor proprietary, and Canonical is not allowed to distribute it, so you may need to download it and install it yourself. This is made easier for you by making a package install for the firmware do the downloads in some cases. Other possibilities are that there might be multiple types of firmware, and rather than use a default which would be wrong for some people, none is used by default.

Hi,
Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).
In order to gather essential troubleshooting information about your wireless card, please follow this procedure:
Step 1:
If you are using the Gnome interface, open the Terminal console via "Applications-
If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.
So the methods in Unity are:
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal
Step 2: Please copy-paste the following command from https:/
Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!
sudo apt-get update; sudo apt-get install hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/
Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.
Step 4: Please also specify the exact model and make of your PC (if known) on this thread
Step 5: Please also clarify if you installed Ubuntu to the harddisk and are running from a harddisk install OR if you are only testing Ubuntu in a LiveCD session.
Regards,
Mark

I installed ubuntu with wubi.
The first command gave me this:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04 LTS
Codename: precise
The second command gave me this:

Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).
Then copy-paste the following commands into the Terminal (using a WORKING, WIRED Internet connection):
sudo apt-get update
sudo apt-get install firmware-
Then please copy-paste each command below one by one into a Terminal. Hit <ENTER> after each command.
echo "blacklist bcma" | sudo tee -a /etc/modprobe.
echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.
echo "blacklist brcm80211" | sudo tee -a /etc/modprobe.
After running the commands above, make sure to select "Load Defaults" in the BIOS, save the configuration.
Then reboot and retest wireless.
