Wi-fi in this laptop was working perfectly with 11.10 version of Ubuntu.
Now, with 12.04.2 or 13.04 it only works with some networks. It works with WEP but I haven't been able to make it work with WPA.
Been looking for a solution but most of them tell you to add some lines to /etc/modprobe.d/blacklist-bcm43.conf, and I guess in my case doesn't help because my ubuntu already comes with that file, with the following content:
# Warning: This file is autogenerated by bcmwl. All changes to this file will be lost blacklist b43 blacklist b43legacy blacklist ssb blacklist bcm43xx blacklist brcm80211 blacklist brcmfmac blacklist brcmsmac blacklist bcma
So, anybody knows how to solve this problem? Thanks
