Connect Nighthawk M1 via USB to your computer. Open up a terminal and connect to the Nighthawk M1 via telnet (IP MAY VARY):
telnet 192.168.1.1 5510
.
You can check the current status of the LTE via the AT!gstatus?
command.
To add more options to your cellular list in the Nighthawk M1 settings, copy/paste the following commands and paste them in the telnet session (you might need to hit ENTER one or two times - just as long until no "OK" comes back):
AT!BAND=3,"1800 Only (B3)",0,4
AT!BAND=4,"2600 Only (B7)",0,40
AT!BAND=5,"900 Only (B8)",0002000000000000,80
AT!BAND=6,"800 Only (B20)",0,80000
AT!BAND=7,"800+900+2600 (B20+B8+B7)",0002000000000000,800C0
After that, just reboot your Nighthawk M1 and find the new options under http://192.168.1.1/index.html#settings/cellular
Does the telnet command works with the firmware 12.06.08 ? because I can't acces to it !
