Not sure which boxes it works with but on the Samsung, it shows the IP info. Next time I'm in the same place as a Scientific Atalanta or the Cisco beanded one, I'll try it to see the difference.

I'm pretty sure they just don't like to give out the info- I asked a T-W installer and he told me about that channel. It would really make sense to be able to measure signal strength by using the box- it eliminates any loss from inserting another device inline.
