Winc15x0Interface RSSI range

I am using the Fez Portal with the latest TinyCLR OS. When I call Winc15x0Interface.GetRssi(), the value is a positive int that increases when the wifi signal is stronger. I am getting around 80 when the signal is really strong. The typical range of the RSSI is -80 to -20dBm, with -20dBm being really strong. What is the range of returned value from Winc15x0Interface.GetRssi()?

the value is converted to 0->100%, this makes more sense for most users.

I guess 80 mean 80% and it is strong.

Thank you very much for the explanation @Dat_Tran . I wish you would have documented the code though…
