I installed ubuntu 12.10 on my Dell Vostro 3460 and no network devices are detected (ethernet and wireless).
when I run lspic, I see: 1:00.0 Network controller: Broadcom Corporation BCM43142 821.11b/g/n (rev 01) 2:00.0 Ethernet controller: Atheros Communications Inc. AR8161 Gigabit Ethernet (rev 10)
Any ideas? Keep in mind my only internet connection is just another computer I'm using, so for installing stuff from the internet I would need to first download them, put them on a USB stick and then copy them and install on the Dell computer.
[Edit] One more thing, 'rfkill list all' lists only the bluetooth device.
[Edit] Ethernet works now, Wireless driver installed, but not functioning.
