If your neighbor has that or anything like what that can do, then your network is at risk, meaning your files as well.
Yes the neighbor has internet, but also yes, might also find access to your files.
Best to change the security on the wireless router to WPA2 with a strong SSID password that all your wireless devices must use to connect to the router.

A next-door neighbor received a laptop Christmas gift today, and our wireless connection is showing on his Network. If he can connect to our wireless, does that give him access to our computer files, etc?? Or does that simply allow him to connect to the Internet with a high-speed connection? How safe is MY computer if he is using my connection? Thanks and Merry Christmas, Bonbon
