It appears to be trying to use a tg3 driver - which is the ethernet.
Follow these instructions to setup the /etc/network/interfaces networking
for Network Manager:
https://help.ubuntu.com/11.10/serverguide/network-configuration.html
Example for /etc/network/interfaces:
auto eth0
iface eth0 inet dhcp
pre-up /sbin/ethtool -s eth0 speed 1000 duplex full
Manual test (non-persistent):
# sudo ifconfig eth0 192.168.1.50 netmask 255.255.255.0 up
# route add default gw 192.168.1.1 eth0
For your wireless:
Please show us the output of:
nm-tool
lsmod | grep b43
sudo iwlist scan
sudo cat /var/log/syslog | grep -e b43 -e firmware -e wpa -e wlan -e
etork | tail -n55
$ sudo apt-get install firmware-b43-installer
$ sudo apt-get remove bcmwl-kernel-source
