Hi everybody...

Have some problems for some time now with the Internet connection. It is randomly lost on my Lucid powered rig (motherboard ASUS P5K) and nothing could help to reestablish it (tried several times the "sudo ifconfig eth1 up" thingie, without luck), but a fresh restart. My ethernet cards are (the first one - an onboard gigabit ethernet card - is in use):

Have anyone had this problem too? Does anyone know what to do to avoid these annoying random connection droppings? Any help would be greatly appreciated... Thanks.
