[Solved]Random 'sendmsg: Network is unreachable'

I just yesterday installed Arch. I installed from USB from the latest LiveISO and use the aui scripts.

Since the first boot I experienced excessive Packet Loss, between 40% and 60%.
Resolving works most of the time, allthough it gives me 'unknown host' every 50%.
Ping to google and my local server

My Ethernet adapter:

03:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0)

(The rest of my system is a Core i7 2700k on an AsRock P67 Pro3 SE)

'ip addr'

'dmesg | grep atl1c'

I am using NetworkManager and I get the IP from my router with a static DHCP lease.

I didn't have the same issuse on Windows (8.1) x64.

Edit:
I just noticed I keep loosing and re-getting my IP Address acording to i3status.

I solved the issue by doing

sudo pacman -R networkmanager networkmanager-dispatcher-ntpd

, rebooting and executing sudo dhcpd

Arch Linux
