I recently purchased a new laptop with a wireless card installed. I was very surprised to click on wireless networks and find one "linksys" listed. When I clicked on it, I connected to the internet. How does this work? Sorry, I’m a dim bulb when it comes to computers.
What you did was connect to the internet through a linksys router that is within your range. The system is unsecure hence no password. All linksys routers come out of the factory with a default network name of "linksys". It is possible for you to log on to the router itself by typing 192.168.1.1 into any browser. The default login name and password are admin:admin.
As mentioned above, this is an unsecure network which means any body can be logged on including potential hackers. If it is a close neighbor, just make sure you don’t get them mad at you for using their system without permission.
