Lenovo X201, ethernet Intel 82577LM, no network

This is the same notebook discussed in
http://bbs.archlinux.org/viewtopic.php?id=98993

It loads the module e1000e. I have arch installed. It loads the module
e1000e and ifconfig reacts. It won't register the ip-address assigned
through dhcp.

Hardware: Lenovo X201 with the ethernet chip Intel 82577LM

# uname -a

# ping 192.168.1.1
Network is unreachable

No routing table either.

Any help to get the network going, is welcome.

For some silly reason, ifconfig needs "up". So I am able to get the interface up
manually with a static address "ifconfig eth0 ADDRESS netmask MASK up".

Getting the address from the DHCP server is still a problem.

Well, I have found a work around:
Not to configure the interface for 'dhcp', which uses dhcpcd, instead call dhclient manually. That configures the interface without any hassle. This is reproducable.

Can anybody explain why? Is this a known issue?

I had this same issue with this network interface, and a friend who uses slackware told me that the .33 kernel renamed a file and DHCPD was not updated to reflect that. He told me to use dhclient manually, but I'm not sure where to find it on the install CD, or how to use it. Any help?

I downloaded the package (the *.xz file) from the repo, for example http://www.archlinux.org/packages/extra/i686/dhclient/ (watch the "Package Actions" box top right), transferred it through USB memory stick to the laptop then "pacman -U ...*.xz".

- Comment out all the four lines: eth0, INTERFACES, gateway and ROUTES in /etc/rc.conf
- kill dhcpcd (dhcpcd -k eth0) or reboot
- do "dhclient eth0".

Thanks, oddly enough the connection in my head I wasn't making for how to do this was that I could use a USB drive. I kept thinking, burn it to a CD, then take out the install disk... Now just 4 hours of class and I can get this going.
