i just got a wireless router going so i can share the internet betwwen 2 computers. Setting it up the software gave it a default address of 192.168.x.x this seems to be the defualt for a lot of them. my question is can i change the default address and is there a good reason for me to do it? Is it harder for someone to get to my router if i change the address or would it have nothing to do with that? My secound question and this is a really novice question. one computer is physically hooked up to my router via ethernet cable, the other is wireless.when i am looking of the internet through the wired computer is my router broadcasting what i am doing over the lan?
