That is from the Sierra Modems, not really a feature of the MOFI. They have a great signal readout that is easy to read. The Quectels have a detailed output that has to be manually parsed for what is what. The Modem-> Connection Status screen should still give much of the info, but you wont get a port by port read out for antenna signal strength until you get into the EM160R-GL or RM5xx series modems. They have commands that can be used (AT+QRSRP)

The first post has a link to the Windows Connection Manager that appears to be broken. I think this is the correct link:

Does anyone know how to delete the Sprint firmware from the MC7355?
I understand generic firmware is now needed for Sprint and it auto selects the Sprint firmware.
It does not properly connect. Well, it seems connected but no traffic.
I have four carrier specific firmware files in the modem.
