I just upgraded from 7.10 to 8.04, and promptly lost all connections to my LAN and the wider internet...
I have two nic cards: an onboard, eth0, and a netgear (GA311, maybe?) gigabit card, eth1. My network/internet comes to eth1. eth0 is currently unused.
manual network configuration displays both as set up with static IPs; however, when I attempt to access network-tools, and I click configure on either interface, I get:
Code:
The interface does not exist
check that it is correctly typed, and that it is correctly supported by your system
here are the results of "lshw -C network" and "sudo ifconfig&&iwconfig" :
