Hi, my internet was connected the previous night and it was at 100mbps bt 40mbps and then the next morning the download was at 0.08mbps and the detect internet said it was on limited access. Nothing changed? Figured problem is with mikrotik setting because the sim card is fully functional please help.

What are the RSRP, RSRQ, SINR and RSSI values ?

Already tried reboot ?
II've seen it happening a couple of times too on sxt lte.
Usually reboot fixed it.

Usb reset of lte could be possible as well but my device is 930 km away which means a reboot is simpler and safer.
