WIFI monitor thinks it's always connected

Q Section, what exactly would these last two options (4 and 5) do?

Choice 4 would be an option to have the plugin start automatically if there is a signal and/or connection or the plugin can be started manually if one chooses. If started manually then the plugin appears but is grayed out and not showing data until user selects 'Start' manually. This would save a little of the CPU and battery resources for laptops (and underpowered desktops).

Choice 5 is a setting for Ad Hoc which is a computer-to-computer connection not utilising any router, access point or other device. This is one of the two settings available using WiFi. Typically the Wireless Client software functions a bit differently when in this mode. For any other questions please post. There are many additional ideas such as an indicator light for Secure Connection, WEP, WPA, WPA2, AES, TKIP etc. which are all different types of encryption.
