Network adapter(Realtek RTL8111/8168B) not communicating with network
Hi LQ forum users

This is my first post on this forum, here goes.

I have recently purchased a new intel system. I am having alot of trouble getting the network card to communicate with the rest of our network.

I am running slackware 12.0, which I have just installed on the system. The problem is that the network is not configuring itself. If i set the network to use DHCP, then all it does is poll for an ip address, timeout and and continue booting. It seems to not find the network or something, because it doesn't get an ip. ifconfig only shows the local host. I then, through netconfig, set up a static ip for the machine. I have used an ip which is not in use (by pinging consecutive ip addresses from a working machine till i get host unreachable). I use the correct gateway/subnet/nameserver settings, and save. If i then run ifconfig, the connection shows up, but i still cannot ping anything except the actual machine.

I will include information from what i think can help (below), please, if you need anything else, just ask, and it shall be done. note that sll this info is taken after setting up the network using static ip.

output from ifconfig:

I am a bit of a linux newb, transitioning from windows caterpillar to linux butterfly, so any help would be appreciated.

Problem solved
Hey everyone, fixed the issue, seemed it was a driver issue, fixed by updating the kernal.

updated from (slackware 12.0's default kernal) to
