LTE disable CA band

RouterOS Wireless Networking
1

Hello! By any chance is some way to disable CA band for LTE? Currently I locked Band 1, because it gives me the stablest connection and doesn’t automatically connect to CA band, just uses primary band.
What I want is to use B3 band (better signal strength), but when automatically kicks in CA band then I start to lag in multiplayer games.
Primary band: B3@5mhz
CA band: B3@20mhz

So is there some way to not allow to use CA band?

RouterOS version 7.1RC3

not by us, users.
You can do a CellLock to lock that earfcn&phy-cell-id what you want as primary-band and this will be your main speed from it.

Tried to disable cells, but router still using them. Also tried it vice versa eg. lock specific cell. I have no idea what im doing wrong

/interface lte set lte1 modem-init="AT%CLCMD=0,1,1417,484,\"24701\",1300,484,\"24701\",1417,437,\"24701\",1300,437,\"24701\""

EDIT: /log print

15:34:00 lte,error lte1: init string failed: AT%CLCMD=0,1,1417,484,“24701”,1300,4
84,“24701”,1417,437,“24701”,1300,437,“24701”

Ahh, Chateau LTE18 user, so rare :).
I starting downloading all PDF to that module and then I will update my answer.

P.S. you should give that information at start, I thinking that you use R11e-LTE6 module…

Sorry, I was expecting that hardware doesn’t matter in this case, just RouterOS version. If someone in the future has similar problem here is newer documentation with more examples.

In my case to lock specific cell, command line should look like that

/interface/lte/at-chat lte1 input="AT+QNWLOCK=\"common/4g\",1,1417,437"




/interface/lte/at-chat lte1 input="AT+QNWLOCK=\"common/4g\",[num of cells],[earfcn],[phy-cellid]"

I read few AT Commands but in Quectel I not see dedicated option to disable CA (Carrier Aggregation) off.
Telit have got a own AT command but not quectel.

Seams only way is set only one band to be active and when you still have CA on differ EARFCN then only CellLock to this one EARFCN can be asnwer - as you write.
