Hi,

How can i lock a specific cell id.

My rut240 is always switching too a slower cell after some time and not switching back too the faster cell (3g).

Or can I prevent auto cell switch in settings?

Hi,

Router do not have such feature for force Cell ID.

But using AT commands via SSH you could try to force Cell ID. There is a risk to lost connection, so remember to which Cell ID router was connected and save all commands and outputs which you was used for recovering.

Commands example:

root@Teltonika-Router:~# ifdown ppp

root@Teltonika-Router:~# /etc/init.d/gsmd stop

root@Teltonika-Router:~# microcom /dev/modem_cmd

ATE1

OK

AT+QCSQ=0

OK

AT+CGREG=2

OK

AT+CGREG?

+CGREG: 2,1,"2620","BCA9802",7

OK

AT+QENG="servingcell"

+QENG: "servingcell","NOCONN","LTE","FDD",250,02,BCA9802,62,2850,7,5,5,2620,-109,-9,-80,15,18

OK

AT+QENG="neighbourcell"

+QENG: "neighbourcell intra","LTE",2850,62,-10,-109,-79,0,18,4,22,10,62

+QENG: "neighbourcell inter","LTE",1602,16,-11,-102,-82,0,18,3,0,18

+QENG: "neighbourcell inter","LTE",3048,62,-12,-114,-93,0,0,4,0,16

+QENG: "neighbourcell","WCDMA",10662,1,0,0,37,-1250,-245,-21

OK

AT+QNWLOCK="common/4g",1,1602,16

OK

+QNWLOCK: "common/4g",0

AT+QNWLOCK="common/4g"

+QNWLOCK: "common/4g",1,1602,16

OK

AT+CGREG?

+CGREG: 2,1,"2620","BCA9805",7

OK

AT+QENG="servingcell"

OK

Ctrl+x

root@Teltonika-Router:~# /etc/init.d/gsmd start

root@Teltonika-Router:~# ifup ppp

Dears,

is it possible to implement a similar script to lock a 3g wcdma cell?

In my neighbourcell list I have something like this (RUT955):

AT+QENG="neighbourcell"

+QENG: "neighbourcell","WCDMA",3038,-935,495,-1000,-75,3,-32768,-

+QENG: "neighbourcell","WCDMA",3038,-935,129,-1040,-115,3,-32768,-

+QENG: "neighbourcell","WCDMA",3038,-935,200,-1060,-120,3,-32768,-

+QENG: "neighbourcell","WCDMA",3038,-935,424,-1100,-145,3,-32768,-

+QENG: "neighbourcell","WCDMA",3038,-935,3,-1050,-155,2,-32,-

+QENG: "neighbourcell","WCDMA",3038,-935,35,-1140,-195,3,-32768,-

+QENG: "neighbourcell","WCDMA",3038,-935,5,-1150,-200,3,-32768,-

+QENG: "neighbourcell","WCDMA",3038,-935,330,-1180,-240,3,-32768,-

It there a QNWLOCK command to lock one of these cells? 
Thank you
