I have 3 computers and they are wireless. I configured my router and set
security keys etc. assisted by my ISP (Verizon). When I go to see all
wireless networks my network has a security lock icon so I believe it is a
good thing. My question is that one of the computers is able to connect to
other networks even though my router is disconnected and using deferent IP
address. Am I doing something wrong?
