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?
