unable to connect to network (dhcp) post upgrade

Dear All,
I'm a newbie Arch user, a couple of weeks ago I successfully installed Arch x64 + KDE4 on my desktop (dual boot with Windows 7) but after few days of the network failed during boot. I tried resolving the issue but couldn't. Since the installation was almost useless without a network, I formatted and reinstalled Arch.

The reinstall was successful but after a system upgrade with pacman -Syu, on rebooting the network failed again.

Since the network was configured dynamically during the net-install from a FTP server, I'm sure there is no hardware issue or problem with the network.

The network works flawlessly on Windows 7 but whenever I boot Arch, I get the following message:

::Stopping Network   [DONE]
::Starting Network   [FAIL] 

(After it stays [BUSY] for a long period of time.)

After several tries of:

/etc/rc.d/network restart

Even if I get

::Starting Network   [DONE]

On trying ping, I get:

ping www.google.com
ping: unknown host www.google.com

On trying to synchronizing the packages I get:

pacman -Syy

error: failed retrieving file 'core.db.tar.gz' from mirror.cse.iitk.ac.in : No address record

                                                             OR

error: failed retrieving file 'core.db.tar.gz' from mirror.cse.iitk.ac.in : Transient resolver failure

Even tried this:

dhcpcd eth0

but got the error:

dhcpcd[1805]: timed out

Lines from my /etc/rc.conf which is unedited after installation:

eth0="dhcp"
INTERFACES=(eth0)
gateway"default gw 192.168.0.1"
ROUTES=(!gateway)

I tried almost everything given in http://wiki.archlinux.org/index.php/Network
Also went through the forum posts and tried few suggestions but have no success.
Without a network my Arch installation is rendered useless.
I haven't even installed X leave alone KDE.

Please help me.
Thanks in Advance.

Is your hostname setup correctly in /etc/.rc.conf and in /etc/hosts ??

/etc/hosts

Show us the output of 'ifconfig -a' and 'dhcpcd -d eth0'.

If the driver for your NIC card is not working or absent you won't be to run ifconfig <iface> up. If it does succeed try downgrading dhcpcd or try another dhcp client like  dhclient udhcpc or pump.

I tried reinstalling this time using the Core packages from the insall cd. Post install the network worked flawlessly but after i upgraded the system with pacman -Syu, the network fails the next time I reboot.

Re: unable to connect to network (dhcp) post upgrade

This seems to be a driver issue. I'm not good at solving driver issue, so I will leave this to someone else. By the time, you can try setting yourself a static IP, it *might* work, or might not, depending on how bad the driver issue is.
