Task Tracker - Obtain WiFi Signal Strength at runtime

I just posted Obtain WiFi Signal Strength at runtime on Task Tracker. Feel free to discuss and make suggestions here.

What is wrong with the RSSI returned from a scan in the WiFiNetworkInfo object? You do a scan when you are connected.

@ Mike - I like to know the signal strength for a portable device. I would like to warn the user if he/she walks away to far from the access point.

Scan("…") throw an exception once connected.

Obtain WiFi Signal Strength at runtime was updated.

Status went from Proposed to Open.
Priority went from Unassigned to Minor.
