# Now the pi needs to be plugged into one of ports 1-4 on the linksys

sudo ifconfig eth0 192.168.1.10

# turn on the router!
# and VERY quickly (you only have seconds)
# so maybe have this typed up and ready to go when you turn it on!

sh wrtftp bbhn-3.1.0-wrt54gs-2.4-squashfs.bin

# wait a few minutes, lights will flash and when they settle, it's finished
