Obviously the installation CD could use the Ethernet connection.
However, it didn't install/configure it.
ifconfig -a only reports a 'lo' interface.
Fortunately, the usb device works...
Couldn't it be possible to copy the device from the installation CD?
$ nm-tool NetworkManager Tool State: disconnected $ sudo lspci -nnk | grep -A10 -i network 0c:00.0 Network controller : Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01) Subsystem: Dell Wireless 1390 WLAN Mini-Card [1028:0007] Kernel driver in use: wl Kernel modules: wl, ssb
OK, and the Ethernet controller is BCM4401-B0 (from grepping 14e4 in the output of lspci -vvnn)
Followed another thread which sent me to look at the content of /etc/network/interfaces There was only lo. So I added there eth0, and restarted the networking service. But it is now in stop/waiting mode...
Skipping service and using directly the init.d script is clearer:
Cannot find device "eth0"
Checked my box at work, and surprise: there's no eth0 interface defined in /etc/network/interfaces, which doesn't prevent ifconfig -a from reporting one... Removed the 'auto eth0' I had previously added, which allows the restart but solves nothing. OK... now the LAN is not plugged.
