i just bought GL-MiFi. when i want to create new connection, i didnt find any option to set the network to 4G/LTE. only saw UMTS/WCDMA. any help? i bought the EC20 module.
This seems to be a GUI limitation. I discovered that LTE is in use by using a command line tool called uqmi. Use as follows:
Enable dropbear/SSH.
Use Putty to SSH into the router.
Type the following:
uqmi -d /dev/cdc-wdm0 --get-signal-info
Should see something like what follows:
{
“type”: “hdr”,
“rssi”: -125,
“ecio”: 5,
“io”: -106,
“type”: “lte”,
“rssi”: -74,
“rsrq”: -8,
“rsrp”: -105,
“snr”: 142
}
I am fairly certain that LTE means what it says.
thanks so much. actually i just found tutorial in the manual, but looks like the tutorial not working.
the tutorial said only need to change to “fdd-lte” on the config the will connect as lte. not working for me.
then i tried your suggestion to use qmi. damn, its working great. even can read & send sms now. but only via terminal. would be nice if can use GUI.
the bad side of using qmi mode, the 3g/4g led not working when using this mode.
update: found solution. need too update device in led list 
You just need to choose umts it should works as LTE.
If you are using v2.24 it will use uqmi automatically.
I agree that it would be nice to have 3G/LTE status and sms facility in GUI.
If I recall, rooter implementation of OpenWRT has this.
