SXT LTE6 kit problem - Dropping LTE connection every hour

Hello,
I have a problem with two SXT LTE6 kit (RBSXTR&R11e-LTE6). Latest stable OS 7.6, modem firmware V034. Purchased fixed IP in LTE T-mobile and Plus operator. RSSI -47dBm, RSRP -67-70dBm. Two different locations, two different BTSs. On each of the devices, every hour, sometimes every two hours, it drops the LTE connection and re-establishes it. Interestingly, on both devices these are always full hours. Have any of you encountered such a case? How to fix it? :wink:
