Router keeps working but 4g disconnects and MR600 doesn't do anything to reconnect by itself.

I already set manual bands as Other post recommend. Also put only 3g and set up dayly reset but that's not a solution because the site is remote and sometimes you need to wait to many hours to the auto reset time.

As I could find this not only my problem and other user are asking a for script's to reset when router get disconnected. 

I think that firmware must allow the router reconnect automatically when lost connection so users not need to reset every day.

Also sms reset is not an option sms+code.
