How many devices do you pass through before surfing the web?
Detect Multiple Routers over at PCWinTech is an excellent program to find your routers.

In our home, I have multiple routers setup and as you can see on the pic below, I am going thru three wireless routers and then the ISPs router. (Reconnected to another wireless router).
