hi, i'm new. i've had a search & can't find anything but might've missed something...
i'd like to use my n800 to see if some cheeky bugger is hacking into my elderly grandparents wifi (think he obtained key). also if any other neighbours have. don't care about getting into other people's networks or snooping but would like to/protect them and if someone is using my grandparents wifi, see what he's downloading / browsing on it (also think he's in their hotmail). is this possible to do? and any help would be appreciated. got root and tcdump and dsniff and aircrack-ng but have no clue what i'm doing - seems to only monitor my n800! cheers guys,
