I am not sure, if my problem belongs to this bug:
I updated a Dell Inspiron from 14.04 Trusty to 14.10 Utopic. It seemed everything ok, but no WIFI.
So i went to Tab "Additional Driver" in "Software & Updates", where my wlan-HW was found: Broadcom BCM4311 (Rev 01).
But, when i choose "Apply proprietory drinver" => after next reboot, there is no network-connection anymore:
LAN Broadcom BCM4401-B0 (Rev 02) and WLAN Broadcom BCM4311 (Rev 01) does not work.

Only after delete of
sudo rm /etc/modprobe.d/blacklist-bcm43.conf
and restart
Network LAN ist working again.
