I'm having trouble connecting to network from the live installation media. (using usb)

I'll run through the steps I take:

boot to usb, hit tab on the 64bit arch option. I disable ipv6 at boot like this

ipv6.disable=1

right away I check ifconfig eth0, and it seems like dhcpcd worked automatically. here's the output (top 3 lines):

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1492 inet 192.168.2.3 netmask 255.255.255.0 broadcast 192.168.2.255 ether f0:de:f1:72:12:bc txqueuelen 1000 (Ethernet) ...

seconds later, I check again and the output is:

eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1492 ether f0:de:f1:72:12:bc txqueuelen 1000 (Ethernet) ...

it lost the IP address! this will continue, seemingly at random. same thing with "ip a" sometimes the eth0 device isn't even listed, only lo.

I can't even ping the router (at 192.168.2.1)

connect: network is unreachable

What could I be doing wrong?? (I checked the cables, there isn't a monkey back there unplugging things)

edit: added the error received after pinging
