I installed Ubuntu 12.04 on a Dell Latitude D620. I didn't expect any issues based on googling this laptop and Linux. However, I cannot get Ethernet or wifi to work.

lspci shows the correct hardware

Ethernet controller; Broadcom Corporation NetXtreme BCM5752 Gigibit Ethernet PCI Express (rev 2)
Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

I went into Network Connections and added a Wired connection and gave it a name and selected the MAc address for eth0 (in the drop down list), and selected automatic (DHCP) as the method for iP4

I looked at /etc/network/interfaces
auto lo
iface lo inet loopback

so I tried adding

auto eth0

but no luck. grep -i eth /var/log/syslog gives

I looked at some forum posts on how to fix this, and the best I found was to edit NetworkManager.conf and set managed=true (it came false out of the box). That did not help.

Thanks for any other suggestions you may have!

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
