 +====== Wi-Fi Signal Strength in Open Mobile and iPassConnect ======
  
 +Open Mobile reports the signal strength as a percentage, and iPassConnect reports the signal strength in decibels (dB). 
 +
 +===== Scoring the Signal Strength =====
 +
 +==== Open Mobile ====
 +
 +Open Mobile reports signal strength as a percentage (with 100 being the highest) with a score from 1 to 5 (with 5 being the highest) as shown in the following table.
 +
 +^ Signal Strength ^ Score ^
 +| 81%-100% | 5 |
 +| 61%-80% | 4 |
 +| 41%-60% | 3 |
 +| 21%-40% | 2 |
 +| 0%-20% | 1 |
 +
 +==== iPassConnect ====
 +
 +iPassConnect reports signal strength as a decibel (the lower the decibel the higher the signal strength) with a score from 1 to 5 (with 5 being the highest) as shown in the following table.
 +
 +<note important>iPassConnect reports the decibel without indicating that it should be a negative value.</note>
 +
 +^ Signal Strength ^ Score ^
 +| X > -45 dB | 5 |
 +| -45 dB > X > -65 dB | 4 |
 +| -65 dB > X > -80 dB | 3 |
 +| -80 dB > X > -90 dB | 2 |
 +| -90 dB > X | 1 |
 +
 +=== Connection Score ===
 +
 +For both Open Mobile and iPassConnect, users should be able to connect if the network has a score of 3 or greater. For Open Mobile, this means a signal strength greater than 40%, and for iPassConnect, this means a signal strength higher than -80 dB. 
 +
 +In some rare instances, users will not be able to connect with a score of 3. In this case, the user may need to move just a little to improve the signal to noise ratio (perhaps a steel column was scattering the signal).
 +
 +===== Command Prompt =====
 +
 +On Windows 7 or Windows Vista machines, the signal strength (as a percentage) can be obtained through the command Prompt.
 +
 +**Using the Command Prompt to obtain the signal strength:**
 +  - Open the Command Prompt.
 +  - Type: ''netsch''
 +  - Type: ''wlan''
 +  - Type: ''show all''
 +
 +Below is a screenshot of the result (with signal strength circled in red).
