Answer #1
thats bad unforutunatley that menas that people are trying to hack your network, you can however, configure your router to ignore all for info and not respond to port scans. As long as you have your WEP key on you have nothing to worry about
Answer #2
Yep thats what i thought but does it take up any of my bandwidth with people trying to do that?
