You not use a Cell Lock by at-chat lte1 input=“atcell=2,3,6400,143" ? Because in CellLock after loose signal at moment you stuck in offline mode. Maybe you assign only B20 or this is your only Band with signal?
In normal mode means at-chat lte1 input="atcell=0” works me automatic migration into 3G (UMTS/HSDPA..)
I can confirm that different SIM cards works me different too.
CellLock at one ISP works with Cameback signal.
Other ISP SIM card works on R11e-LTE6 and USB E3372 and many devices like phones but not work in first version “SXT LTE 3-7”.
At screen I see similar situation to my report http://forum.mikrotik.com/t/v6-46-1-stable-is-released/135478/1
.
I’ve already tried changing MTU, other things that I don’t remember now, but the stupidity of all of this is that if I change from LTE to 3G I get Internet…
It’s like you do CellLock at 3G… OR you select that Band who works you only at 3G.
Please do:
interface lte set lte1 allow-roaming=no band="" modem-init="" network-mode=lte operator=""
# wait to new connection
interface lte at-chat lte1 input="AT*Cell=0"
# wait to new connection
/interface lte at-chat lte1 input="AT+RESET"
# wait longer because lte1 will disapeer from device
system routerboard usb power-reset
# wait longer because lte1 will disapeer from device
system resource irq print interval=1s where users~"usb1"
# COUNT is still upper?
Same SIM in a Huawei B something works perfectly… Does anybody knows what the hell is going one here?
PS: The LTE Cat4 modem works fine with tha F… SIM card…
In general this is bad re-connecting stuff from MikroTik and we all try send own supout.rif to support@mikrotik.com to produce better modem firmware who give us good stability, proper 2xCA and after long signal-off situation automatic registration in network and connection without own scripting.
