Modem issues while dowloading large files using Sierra MC7455 on RB912UAG-5HPnD on 7.1-rc1 and 7.1-rc3

My router is having internet gateway via LTE and LAN via ethernet and/or wlan

When downloading large files over LTE (with a device connected to the router) it looks like after some time the modem is not responding, while the LTE interface stays on and appears to be running. also the file download is stuck and there is no internet connection anymore.

The LTE interface is still running but the RSSI is not updated and AT-commands don't work (timeout). Also interface lte1 enable and disable timeouts via cli

Running '/system routerboard usb power-reset duration=5' brings back the modem to a working state
