I will try to help you. But first, you must have realistic expectations:

2. If you are attempting to fix this from your phone, this is unworkable. You need to have access to another machine from which you can, at a minimum, download driver modules and transfer them to your non-working machine using a USB key.
3. You will have to be prepared to spend appreciable time on this problem and be in a position to be patient waiting for answers.
4. The problem may never get solved, despite our best efforts.
If you are okay with all of the above, then I can try helping. Otherwise, it is best to:
1. Take your critical data off your HD by installing it in another working Linux machine and copying the data to an outside drive. Then install a pristine 12.04 system and see if that solves it,
2. Take your computer to a computer shop and pay for an expert solution,
3. Back up your data as per #1 and then either install your old OS whether it be Windows or the old version of Ubuntu that recognized your machine.
If still okay, then here is the problem as I have researched it:
Your wireless module is a Realtek RTL-8185 wireless card. (last line of your LSPCI output). This wireless module is not supported in the Linux kernel (see here):
The attempted fix involves blacklisting the defective Realtek module and substituting a Windows driver using a software kludge called ndiswrapper. Normally, I hate using ndiswrapper, but in your case, it seems to be the only work-around. The instructions for doing this can be found here:
You may need to substitute the wireless drivers disk that came with your version of Windows. Since you have not given any further details as to the make and model of your computer, etc. I can only provide general instructions.
Make sure that you read the entire posting before proceeding. Print it out if you have to. Treat the instructions as an example, and review carefully where the drivers are on your Windows disk and what the drivers are actually called. Where the example gives:
you will have to substitute both the location and the filesnames with the filenames on your utilities disk.
cd /media/cdrom0/wl8185\ PCI/Driver_1097_2KXP_0201/WINXP/
cp net8185.inf ~/.driver/
cp rtl8185.sys ~/.driver/
If you follow these instructions carefully, hopefully it should solve your problem.
PS I am busy throughout the weekend and into next week. I will look into the forum form time to time, but do not expect a quick response from me. Others may be willing to dive in. Patience and courtesy will always serve you well in here.
