Blacklisting module b44 by bcmwl seems unlogical because bcmwl does not offer any driver for bcm4401. This issue does not exists while using saucy live cd enviroment, but after installing saucy you do not have ethernet connection Steps to reproduce: install saucy 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1244587/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
