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 Network Manager[2029]: <info> (eth0): new Ethernet device (driver:'tg3' ifindex: 2) Network Manager[2029]: <info> (eth0): exported as /org/freedesktop/NetworkManager/Devices/0 Network Manager[2029]: <info> (eth0): mow managed Network Manager[2029]: <info> (eth0): device state change: unmanaged -> unavailable (reason 'managed') [10 2 0 2] Network Manager[2029]: <info> (eth0): bringing up device Network Manager[2029]: <info> (eth0): preparing device Network Manager[2029]: <info> (eth0): deactivating device (reason 'managed') [2] kernel: [1815.448547] ADDRCONF(NETDEV_UP): eth0: link is not ready kernel: [1815.449321] ADDRCONF(NETDEV_UP): eth0: link is not ready 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! Mark
