Disconnected from wireless network - Ubuntu 12.04, Sony VF

Question

I bought a Sony VAIO F series (SVF15A1C5E) recently with Windows 8 on it. I installed Ubuntu 12.04 and just kept a recovery partition for Windows as I do not need it. Unfortunately I cannot connect to the Internet either wired or wireless. I have seen and read the similar topic and tried most of the answers unsuccessfully (I might have done something wrong when applying the answer to my case though) I also asked my department IT but they could not solve it.

The output of lshw -C network is:

I also edited /etc/NetworkManager/NetworkManager.conf so that managed=TRUE while it was =FALSE. Any suggestions?

Do you still have your Ubuntu 12.04 install DVD or USB? – chili555 Feb 17 '14 at 16:04 — chili555, Feb 17 '14 at 16:04

I believe the package you need is on the install USB. Please insert the USB and when the file manager opens with the contents of the USB, select pool > restricted > b > bcmwl > bcmwl-kernel-source > bcmwl-kernel-source-xxx.deb. Right-click it and select 'Open with Ubuntu Software Center.' After it installs, your wireless should be working. It may take a reboot.

If it complains about the dkms package, it is also on the USB at pool > main > d > dkms > dkms-xxx.deb. You might try installing it first and then bcmwl-kernel-source. You should be trying to install the deb files within, not the entire directory.

If you cannot install either from the USB, drag and drop the deb files to your desktop and do:

cd ~/Desktop
sudo dpkg -i *.deb

thanks for helping! I tried it but I needed to install the dkms package first. I tried to install it using a separate usb but I cannot install anything through the ubuntu software center as the install button is frozen (I can't click on it) I tried to do it from the terminal using sudo software-center but I was no more lucky, it looks to me as the usc needs connexion to the internet to install the package. I followed the comments in this question as well as the there-linked pages but I am still unsuccessfull. – cenzo Feb 18 '14 at 12:41
Please see my edit. – chili555 Feb 18 '14 at 15:01
I had just come across using dpkg -i when you edited your post! this worked very well, thanks again. – cenzo Feb 18 '14 at 16:43
