That is good news. It means that the bcm4313 card will work with the default brcm80211 driver. What you need to do is to get your permanent installation back to its default state with regard to the wireless. There are two things to consider. You had obviously installed the STA driver, but what I'm puzzled by is why you were having problems with it. On my HP netbook, the STA driver works just as well as, if not slightly better than, the default brcm80211 driver. Did you install the bcmwl-kernel-source package with Software Centre or Synaptic or did you use the Additional Drivers Utility? Or did you install it some other way?

This is what I suggest you do:
1 - Open the Additional Drivers utility and see if it is telling you that the STA driver is enabled. If so, disable it and reboot. It's unlikely that the wireless card will be working yet because there are one or two steps to go through. If Additional Drivers was not telling you anything coherent, open Synaptic, search for bcmwl-kernel-source, mark for complete removal and "apply". Reboot. If Synaptic is telling you that bcml-kernel-source is not already installed (and Additional Drivers wasn't helping) stop there and post back with the answers to my questions above.
2 - If you've got this far, you need to check some of the files in /etc/modprobe.d to make sure brcm80211 is not still blacklisted. In the commands that follow you will be opening system files in a text editor with root privileges. Take care! Open a terminal, and:
If a blank file opens, simply close it without saving anything. If the file contains this line:
gksudo gedit /etc/modprobe.d/blacklist-bcm43.conf
"Comment" it so that it looks like this:
Save and close it. If the "blacklist brcm80211" line is not present, simply close the file. Now:
This is the file you were recommended to create in your previous thread. That will probably contain a single line "blacklist brcm80211". If so, simply comment it as before with a # at the beginning of the line, save the file and close it.
gksudo gedit /etc/modprobe.d/blacklist-brcm80211.conf
Lastly, it would be a good idea to check all the other files in /etc/modprobe.d to make sure none of them have the line "blacklist brcm80211". Browse to /etc/modprobe.d in a nautilus file browser window and double-click on each to open it in a read-only text editor window. Check that there are no "blacklist brcm80211" lines.
Now, in a terminal:
Does the wireless now work? Whether it does or not, reboot. Don't do the modprobe command, but check the wireless. Does it work?
sudo modprobe brcm80211
Lastly, let's see if the package manager is inconsistent. From a terminal:
You will get output, but are there any errors?
sudo apt-get update
