I have the 4312-LPHY chipset and the only way for me to get wifi to work correctly and consistently is to install the bcmwl-kernel-source package.
With kernel 3.7 and up all versions except "bcmwl-kernel- source_6.30.223.30+bdcom-0ubuntu1_amd64.deb" gives me a kernel panic. This made 13.04 unusable for me until I got the workaround to install the previous mentioned package. Any other driver combination apart from bcmwl makes my WiFi to disconnect and ask for authentication every 5 seconds and is thus not usable. Not sure if the above is of any significance to what you are proposing but please don't remove the bcmwl-kernel-source option as an option ;) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1097519 Title: Wrong driver used for older Broadcom chipsets To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1097519/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
