I'm using The Dude to keep a log of CQI and RSRP, and graph them, so I can make an objective comparison when switching antenna and changing antenna position (height, location)
Today the link went down for a moment, then came back up, but since then CQI has been missing. If I open a terminal on the router with the LTE modem and run /interface lte info lte1, I still don't see it.
Code: Select all

Update: Upgrading the modem firmware hasn't made any difference.
Further update: It's reappeared just as mysteriously, about 30 minutes since the upgrade completed.
