I just installed Ubuntu 9.04 on a brand new Acer Extensa 5635Z laptop, but ethernet networking does't work (wireless doesn't work either, but I'd be happy with ethernet for now).
eth0 isn't listed in /etc/network/interfaces:
$ cat /etc/network/interfaces auto lo iface lo inet loopback
lshw does show the nic, but I can't make much sense out of the information:
$ sudo lshw -class network -sanitize *-network DISABLED description: Wireless interface product: AR928X Wireless Network Adapter (PCI-Express) vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:07:00.0 logical name: wmaster0 version: 01 serial: [REMOVED] width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix bus_master cap_list logical ethernet physical wireless configuration: broadcast=yes driver=ath9k latency=0 module=ath9k multicast=yes wireless=IEEE 802.11bgn *-network UNCLAIMED description: Ethernet controller product: Attansic Technology Corp. vendor: Attansic Technology Corp. physical id: 0 bus info: pci@0000:09:00.0 version: c0 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vpd cap_list configuration: latency=0 *-network DISABLED description: Ethernet interface physical id: 1 logical name: pan0 serial: [REMOVED] capabilities: ethernet physical configuration: broadcast=yes driver=bridge driverversion=2.3 firmware=N/A link=yes multicast=yes
Thanks for your help!
