Public bug reported:
Both packages for Precise and Quantal end up blacklisting module 'b44'
which is required for wired internet connection to take place. After
boot the wireless works perfectly but the wired internet is not present
at all and plugging in a CAT5 connection does not wake it up. I can
'modprobe b44' manually at the Terminal and the wired internet module
wakes up and functions again.
/etc/modprobe.d/blacklist-local.conf
blacklist b43
blacklist b44 <--?
/etc/modprobe.d/broadcom-sta-common.conf
# wl module from Broadcom conflicts with ssb
# We must blacklist the following modules:
blacklist b44 <--?
blacklist b43legacy
blacklist b43
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
install wl /sbin/modprobe --ignore-install wl $CMDLINE_OPTS
Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
<--module 'b44'
Network controller: Broadcom Corporation BCM4321 802.11a/b/g/n (rev 03) <---
Broadcom ST Wireless 'wl'
The package should not be blacklisting the 'b44' module if the Ethernet
controller hardware is present in addition to the wireless controller.
It's my understanding that the wired connection was merged into the
Kernel at version 2.6 and doesn't need a separate driver so it should be
allowed to boot up. I worked around this problem and manually commented
out the blacklist and after booting up both connections worked
flawlessly without any manual steps.
