I believe my wireless network was compromised earlier this evening. While attempting to connect to an instant messenger client, my internet connection ceased twice within about a five minute period. Additionally, the computer icon appeared near the clock. This was odd since the only active connection from my desktop is plugged directly into the router. I have been noticing decreased speeds the past few weeks, but nothing as dramatic as this. I immediately disconnect the router, waited a bit, and reconnected. As quickly as I could, I turned of SSID broadcasting and changed my WEP key. Can anyone offer any additional suggestions to ensure this does not happen again. Further, should I contact Verizon? Thank you.
Replace wep with wpa/2, infinitely more secure.
Turn off wirelss completely if you are not using it.
