RUTX14 locking cell tower error

Hi everyone, I currently have a RUTX14 on firmware 00.07.09.1. In my area there are 2 main 4g towers that gives connection. One is usable while the other is not. When my router is in auto mode, it would very frequently switches to the unsuable tower. I have read up the Teltonika guide for locking cell tower and followed it to no avail.

It would always shows ERROR on Putty SSH interface after I put in the command
gsmctl -A ‘AT+QNWLOCK=“common/lte”,2,,’

I have checked my spelling and EARNCF, PCI very carefully but it is still not working. Any thoughts?

Mine is a Quectel modem btw.

Hello,

I would like to inform you of the modification in the cell tower locking command for the RUTX14. Since the original configuration example was posted on the wiki, the correct usage of the command has been updated to:

gsmctl -A ‘AT+QNWLOCK=“common/4g”,1,,’

Please note the following changes:

“common/lte” is now “common/4g”
The number “2” has been changed to “1.” This number specifies how many cell towers the device will lock to. If it is necessary to lock to more than one tower, this value can be adjusted, and additional EARFCN and PCI values should be included accordingly.

Additionally, you can use the command below to explore the available options for this functionality:

gsmctl -A ‘AT+QNWLOCK=?’

I hope this clarifies the changes in the command. If you need any further assistance, feel free to ask.

Best regards,
