thanks ikegami, in windows 7 the "Show icon in notification area when connected" is omited, and the wireless icon is very poor like this picture: http://img408.imageshack.us/img408/9881/geierfig01.jpg and can't be changed, it is not animated. many people are complaining from this omission
try google (windows 7 network icon) there are many people unsatisfied by this.
