It's work for me on a Acer Aspire TimelineX 1830T. I have done an update to Ubuntu 12.04 from ubuntu 11.10 64 bit.
Some info of my config : $ sudo lshw | grep 802. produit: BCM43225 802.11b/g/n configuration: broadcast=yes driver=brcmsmac driverversion=3.2.0-24-generic firmware=N/A ip=192.168.1.44 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn $ uname -a Linux quentin-Aspire-1830T 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux And I have added blacklist acer_wmi to /etc/modprobe.d/blacklist.conf A small story : It's worked on Ubuntu 11.10 after those operations : - install the proprietary driver - add blacklist acer_wmi It worked well except on wpa2. With a wpa2 key, the internet worked 5 seconds after connection, after the connection status was ok, but i cannot access internet. Ask me if you want more details. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987364 Title: Broadcom 43225 wireless not working on lubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/987364/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
