In LTE mode, the sierra modem (MC7710) gives no indication of signal
quality in nm-applet. It looks like icon "gsm-3g-none.svg". I suspect
this is caused by this in the modemmanager debug log when connected:
modem-manager[25672]: <debug> [1349256755.558392] [mm-at-serial-port.c:334]
debug_log(): (ttyUSB3): --> 'AT*CNTI=0<CR>'
modem-manager[25672]: <debug> [1349256755.579056] [mm-at-serial-port.c:334]
debug_log(): (ttyUSB3): <-- '<CR><LF>*CNTI: 0,LTE<CR><LF><CR><LF>OK<CR><LF>'
modem-manager[25672]: <debug> [1349256758.802283] [mm-at-serial-port.c:334]
debug_log(): (ttyUSB3): --> 'AT+CIND?<CR>'
modem-manager[25672]: <debug> [1349256758.821538] [mm-at-serial-port.c:334]
debug_log(): (ttyUSB3): <-- '<CR><LF>+CIND:
5,0,1,1,0,0,1,0<CR><LF><CR><LF>OK<CR><LF>'
The signal is good (I measure download rate of 37 mbits/s), and in 3G/2G
mode I get the correct signal quality indication.
