Follow das BlinkenLights in my new home network set up... my web browser tickles the led on the 802.11 card which tells the wireless base station which has makes two lights blink (one for wireless, one for ethernet)... that second light is talking to the broadband router and more lights blink, one from the base station and one going out on its WAN port... to its supplier, the cable modem with its own array of blinking lights! Pity our poor guests who have to sleep in the guest room where most of these lights live.
