I have a dual boot (windows 7 and ubuntu 12.04) setup and, for (apparently) no reason, I can't connect to any wireless connection on my ubuntu box at all. (on Windows it works.)
I think it stopped working on the first reboot after it has been upgraded (regular updating via cli apt-get).
I can still see the connections on the top toolbar but, upon trying to connect to them, I get asked the password and then it tries to connect for about 30 seconds and then times out.
After looking for answers on the web I thought that posting the output of sudo lshw -C network
would help the people who try to help me:

There is another entry for the Ethernet. But I didn't think it's very relevant to the problem at hand.
I have no internet access so I can't install stuff from the repos.(I'm writing this from a spare netbook I have)
My kernel version is 3.2.0-36-generic-pae
In my modprobe.d/blacklist.conf
file, I have these lines:
# replaced by b43 and ssb
blacklist bcm43xx
Thought it might be relevant.
what i have tried so far
- delete
/etc/resolv.conf
- didn't work add the following entries to
blacklist.conf
(in addition to the ne that was there already)and reboot: - didn't work either
blacklist b43legacy
blacklist b43
blacklist bcma
blacklist ndiswrapper
blacklist wl0
- the steps described on this answer - didn't work wither
