I have written in the past about how the old wireless WEP protocol is no longer safe. You need to upgrade your WiFi access point and the computers in your house that use WiFi from WEP to WPA. The WEP protocol that is still the default on most WiFi access points and routers can be easily broken by any clever computer user with a few simple tools.
