Hi, we have a few TRB255 routers on diferent sites, on some places the 4G signal is weak and we are having issues receiving data from those places.
The SIMs we have can be used both on Narrowband or 4G depending on the configuration we have on the router.
The problem is that when we choose “M1+NB auto” on the Network → Mobile → Connection
The connection is always using M1 event on connections with -91 RSSI.
Is it possible to configure the setup so i there’s a signal limit that forces the connection to be using narrowband when the signal drops below a value?
