Before was able to work with days without disconnection using VPN.
Now, I got dropped every noew and then.
What changed, relocated to 2nd floor and external outdoor antenna to terrace.
There seems to be a problem on power line or line noise.
Noticeable disconnection when appliances are turned on.
4G seems to be keep showing on the logs but have another mr600 with same sim network that is stable with very minmal disconnection.
Tried swapping sims. Using extension with line noise filter.
Haven't tested with UPS or AVR yet.
Thanks a lot in advance for any feedback.
