I have my guru plug plugged into my main router via the eth0 and spawning an AP w/ DHCP on wlan0

every now and then, when the dhcp lease has expired on my main router and a windows laptop requests a new dhcp lease, the guru plug responds on the eth0 interface with a dhcp offer (not what I want)

both my main router and the guru plug AP portion are using the default subnet mask of 255.255.255.0 - is this the culprit?

I've had my plugs computer for a couple of days now and I've learned to control the leds

I was hoping to apply one of the LED functions to a "Internet Status" indicator similar to how many other routers have function to let you know visually that the router has a connection to the internet.

How might I accomplish this with the guru plug (standard)
