I downloaded the latest ISO image from the Arch Linux website and burned the .iso file on an USB drive with some of the many tools you can find on the web.
Once I get on the shell screen I try to test my connectivity to the internet, but it doesn't work. My Ethernet card is correctly detected (I can see it if I do ifconfig) and is also in an "up" state.
I already tried to manually set the configuration using ethtool but with no luck. Also, I already tried re-activating the DHCP service but still no luck. I tried to bring the interface up/down and manually configure an IP address but it still doesn't work.
I searched in dmesg and as far as I can tell the r8xxx module of the kernel for my realtek card is loaded correctly.
I am really running out of options. The most frustrating thing is that only with Arch Linux I have this problem. ALL the other distros run just fine, getting an IP address from DHCP with no intervention from myself what-so-ever, so it's not a compatibility problem here but a configuration one.
I also noted that the dropped packets count increases as time goes by.
Here is some output from the commands:

I also tried running simply "dhcpd" and it seemed to work (he saw my router and leased me an IP address) but at some point it timed out and didn't get an IP.
