Unknown "Wireless Client" Using my My Airport Extreme WiFi
I have been using an Airport Extreme for several years for my home WiFi. I have not been in the habit of ckecking it out with the Airport Utility very often as it appears to work flawlessly. However when I opened Airport utility today I founfd under "Wireless Clients" a device listed as "Android.local" in addition to my several identifiable Apple devices. I have no Android device. Could this mean someone has managed to find my WiFi password and log-in? If so does this constitute a threat to my overall network devices including desktop Mac, iPad. and a couple iPhones? ...or possibly some even larger unknown threat? Should I change the WiFi Password?
Thanks in advance...
