Network Error - Can't Install

Hi,
I've been attempting to install Arch on one of my computers and for some reason the network is not working properly and thus I cannot run pacstrap to install the system.

I'll detail all of the steps I do after booting up.

Upon startup, I perform the following:

root@archiso ~ # ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0: <BORADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 74:d4:35:09:b3:60 brd ff:ff:ff:ff:ff:ff

This gives me my interface name which is enp3s0, and lets me know that the interface is up.

Then I do

root@archiso ~ # ip addr show enp3s0
2: enp3s0: <BORADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 74:d4:35:09:b3:60 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::76d4:35ff:fe09:b360/64 scope link
       valid_lft forever preferred_lft forever

Since I don't have an IPv4 address, I have to set one up. I have a few options (which have all been attempted, to no success).

Before any of these, I disable the DHCPCD service

root@archiso ~ # systemctl stop dhcpcd.service

Option 1:

root@archiso ~ # ip addr add 192.168.1.121/24 dev enp3s0
root@archiso ~ # ip route add default via 192.168.1.1

Option 2:

root@archiso ~ # ip addr add 192.168.1.121/24 broadcast 192.168.1.255 dev enp3s0
root@archiso ~ # route add -net 0.0.0.0 netmask 0.0.0.0 gw 192.168.1.1

Option 3:

root@archiso ~ # ip addr add 192.168.1.121/24 broadcast 192.168.1.255 dev enp3s0
root@archiso ~ # route add -net 192.168.1.121/24 netmask 255.255.255.0 gw 192.168.1.1

I've tried netctl a few times however it hasn't seemed to work (it only was able to start and enable the interface once, though there was still no internet).

For additional information, I have Gigabyte GA-970A-DS3P Motherboard with an onboard Realtek RTL8111/8161 Gigabit Ethernet Controller (I've read the networking configuration page on the wiki and the WOL doesn't seem to be the problem).
The computer's firmware is a UEFI/BIOS cross.

Also, my output from:

root@archiso ~ # uname -rvo
3.12.1-3-ARCH #1 SMP PREEMPT Tue Nov26 11:17:02 CET 2013 GNU/Linux

Also, other computers I've tried on the network have worked fine with an Arch installation.

Finally, I've also tried running a Windows install on the computer to see if a Windows Operating System (Windows 8) can access the internet, and it can. For an additional test, I've also successfully connected to the Internet with a hackintosh (Mavericks 10.9) install.

Thanks in advance!

Re: Network Error - Can't Install

What are the specific error messages you see?   I've a couple comments.  Based upon what you have written, you should have a static address (assuming your router uses subnet 192.168.1./0/24), but you have not set up any DNS services.   You should be able to ping 192.168.1.1.  You should also be able to ping 66.211.214.131 (an Arch Linux server).  If you can do that, then it is DNS issue. 

Second. rather than use a static address, lets try a dynamic address again.  I do not believe that dhcpcd was actually running.  At the point where you've an IPv6 address, but no IPv4 address, run sudo dhcpcd and see what happens.  If it does not work, post the output back here.
