I have connected three Quad Nic cards and using ubuntu 12.04LTS. When I boot up the machine two ofthe D link Quad Nic cards show device not ready. When I issue sudo killall -9 NetworkManager, device not ready disappears but still ports doesnt get up. The third card (Digital Equipment Dechip 21142/43) got greyed after kiling the network manager Following are the different outputs suggested on different forums: All three of the Quad Nic cards are not working
