Why so many devices between my laptop and the wireless router?

[yky]

I have a Cisco Linksys E1200 router. Three computers are wired to it while my laptop connects to it wirelessly. When I look at the network topology (Network and Sharing Center->See full map), it shows that my laptop is connected to E1200 (this one has the same name as the router but different icon. The icon has an antenna. Thus, I think it is some kind of wireless device) which is connected to a switch, then a hub, then to the E1200.

Why are there three devices between the wireless router and my laptop?

Just a quick guess....

Is one of the "wired" computers set to use Internet Connection Sharing? My dad (80 y.o. and still buying the latest hardware) did that once in the XP days and had an issue similar to yours. He never lost connectivity, but took the long way to get there. Found the issue doing a traceroute.
