[closed]dhcpcd - DHCP client can't get an IP on regular networks.

For some reason, my RPI running Arch Linux doesn't get an IP when connected straight to my internet without any firewalls (fiber 100/100 connection).
It was working for about two weeks ago and now nothing, no DHCP offer from any server (Tried two different ISPs, both fiber optic connections).

Whenever i switch to a local network it works, for some unapparent reason:

incoming packet from : .B8.27.EB.0F.73.31
<-DHCP_DISCOVER received, xid:B603F917
->DHCP_OFFER sent, IP:192.168.15.2, xid:B603F917

incoming packet from : .B8.27.EB.0F.73.31
<-DHCP_REQUEST received, xid:B603F917
->DHCP_ACK sent, IP:192.168.15.2, xid:B603F917

I don't really know even where to begin searching for any faults.. so any help would be appreciated because i refuse to just wipe and re-install the system :)
All I\ve tried is:

dhcpcd eth0

which says.. well nothing really :/

Try dhclient. If it works, then maybe you have discovered a bug in dhcpcd, if not then something is wrong with your network.

Cheers will try that out, otherwise i'll dump the tcpdump data for the DHCP chain and hopefully that will shed some light on the whole dilemma.

Just out of curiosity, how would i go about adding dhclient to the bootup process and replace dhcpcd?
I have no /etc/rc.local and i can't really find where the system runs dhcpcd to begin with (i have no /etc/rc.d/dhcpcd either)...

I love arch linux, i just have a hard time finding all the different mechanics of it..

https://wiki.archlinux.org/index.php/Arch_Boot_Process   <-- Differs from the release you get for Raspberry pi it seems..

And perhaps dhcpdump would be a nice addition to archlinux?

I am sorry I didn't notice that you were using raspberry pi. It is a separate project and they have their own forum.

ps: dhcpdump is available in the AUR.
