Hi, I have mifi with the EC20-E 4G EU module.
But I can’t connect to 4G. It automatically goes to 3G and I can’t change it.
How can I force it to 4G?
I’m from Australia on the Optus network.
Thanks.

Choose network mode

set modem to only LTE

echo -e "AT+QCFG=\"nwscanmode\",3,1" > /dev/ttyUSB2 

set back to auto

echo -e "AT+QCFG=\"nwscanmode\",0,1" > /dev/ttyUSB2

 

Thank you. Got it!

@alzhao
Fancy meeting you here
I still have the issue that
I’ve been using
AT+QCFG=“nwscanmode”,3,1
to lock to LTE, and it works when I check the value… But it doesn’t survive a reboot.

I think it should survive a reboot of the device.

Any thoughts on that? When you execute the command, what ‘port’ are you sending it to?

The command should survive a reboot.

Not sure why in your case.

Except for force LTE, can you try lock band?

Have you contacted me by email?

@luochongjun Yes, we chatted by email. It is supposed to survive a reboot but doesn’t. I’m busy trying to get the device to stay connected, so chasing the LTE issue is secondary. But it should still work.
