I have a very strange problem with my fresh install of Archlinux. I have searched through the forums and online for quite a while and have been unable to find anyone with the same problem.
I have my arch install connected to a router along with a computer running ubuntu server 8.10, and my laptop running fedora 11. The other 2 computers connect fine, I have never had any problems with them. After I boot up the arch computer and log in, I am able to ping the other 2 computers and the router, and even attempt an ssh connection to them. Each of the other 2 computers can also ping the arch computer. But after about 30 seconds, all network connections to and from the arch computer stop working. Any ssh sessions that may have started become unresponsive. Any pings that are running turn into "Destination Host Unreachable" from both ends (pings from the arch computer or to the arch computer). It stays this way no matter what I do with dhcpcd, or ifconfig, until I restart. Then the process repeats.
I tried using my routers "ip reservation" to force it to use a specific ip address, but that did not change anything. (I didnt really expect it to) I have also used ifconfig to manually specify an ip address, also to no avail. In /etc/rc.conf i have... (this is part of rc.conf, not all of it)
eth0="dhcp"
INTERFACES=(eth0)
gateway="default gw 192.168.0.1"
Routes=(!gateway)
my router's address is 192.168.0.1
ifconfig's abridged output:
ip: 192.168.0.100
bcast: 192.168.0.255
mask: 255.255.255.0
MTU:1500
Metric:1
I am able to ping 192.168.0.100, and 127.0.0.1
route -n:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
Occasionally my ip address is something other than 192.168.0.100, for example 192.168.0.120 (the dhcp range on my router is 192.168.0.100 to 192.168.0.120)
Currently I have no internet connection to the router, it is just for local connections. If i need to though, perhaps to test pinging outside the lan, i can get an internet connection.

Fixed, by getting a new NIC.
