We are using mikrotik LHG R 6.45.8 (long-term). with LTE

Everything works properly for a period of time, then internet connection become poor, and as soon as i reboot anntena it self everything back to normal.

is there any tips and tricke how can i avoide reboothing

that is the current LTE resoulte see picture

Have you tried to reboot the LTE modem alone when this happens, to see whether the modem or the router are guilty?
/system routerboard usb power-reset bus=X
try X from 0 to 5 until the /interface lte print stops showing the modem, I haven't found a way to identify the bus in advance, and I don't have an LHG R (trying on LtAP which has a different CPU than LHG R).
Also, if the LTE card is a Mikrotik one, what does /interface lte firmware-upgrade lte1 upgrade=no show?

yes, issues is LTE itself,power-reset bus=X--solving the issus
i didn't put on my first post, my bad.


/interface lte firmware-upgrade lte1 upgrade=no show? -- im not sure what this does,and from where can i get the current resoult optios are yes/no,

firmware-upgrade lte1
installed: MikroTik_CP_2.160.000_v013
latest: MikroTik_CP_2.160.000_v018

do i need to update?

Signal measurements, shown in screenshot, are weird. RSRP (signal strength) is pretry good at -77dBm while RSRQ (signal quality) is relatively bad at -11dB. As modem reset resolves the problem fir a while I'd say modem is misbehaving and modem FW upgrade is recomended thing to do IMHO.

Same opinion here. Are you at the site or 14000 km away? In any case, make sure that the RouterOS is at least 6.47 before upgrading the modem firmware. I've ended up with a bricked R11e-LTE6 after an upgrade with an older RouterOS.

interface lte firmware-upgrade lte1 upgrade=yes

Optus the OP has, you'd be lucky to get a signal sitting on top of a tower ;)

We too, but MikroTik not give us a ReleaseNote with KnowProblems and ChangeLog to check what was fix... it's mistery for us too.
