i recently got a router for my computer, my sisters, my brothers, and my xbox. its a wireless router but none of our computer is connected through wireless, its through a ethernet cable. i didn't set a password yet but i was planning on doing that tonight when i noticed a computer was connected to my wireless router. i remembered the ip address and the name. is there a program that i can use to sniff them out or figure out who it is? i set a password and then i couldn't connect so i took the password off till i figure out how to connect after setting it. they wasn't connected anymore after that so far. i have a netgear router. any help connecting to the internet after setting a password for the router would be great too.
