LTE problem

Good morning,

I've been using a MIKROTIK ROUTERBOARD SXT LTE6 kit SXTR&FG621-EA 2023 edition for about 6 months and I'm having a problem every time the BTS is rebooted or turned off.
Basically, it doesn't connect to the bridge even if I have 3G and LTE turned on. Every time I'm offline, I'm forced to go into the settings, turn off LTE, wait a few seconds for the 3G bridge to connect, and only then select LTE. It's happened about 6 or 7 times in about 6 months.

I'd like to fix this because I use the connection for video surveillance in a country house.

thanks

First time I read that.

  1. Autoreboot with watchdog.

  2. Export config.

If it were me, I’d disable the 3G option entirely as more and more service providers worldwide are discontinuing it’s usage. This would then remove entirely a portion of the problem and create a starting point toward resolution.

Afrer that, what @rextended said.
