hi pradeep

i dont quite understand what u mean by this sentence: "..where the router uses the ISP's gateway to connect to the internet" that was what u replied with in ur reply to my first question. What do u mean by 'gateway' and what do u mean by private ip, if ive hacked someone's network i have got my own individual IP address and not theres? I mean im not sharing theres i.e. the person's connection i've hacked?

I know u said that a person cannot hack into my laptop system, but with wireless and a person knowing my wireless IP ADDRESSS can they use that to send me malicious spyware programs or anything that can download on my laptop which by that way can give them access to my personal details?

Sorry Im not really good with computer terminology if u wouldnt mind explaining this and clarifying this situation and concern i have for my personal details.
