GL-E750 wrong 4G signal displayed - evolutions

Device: GL-E750 C6. V3.105

I have noted the following:

  1. Discrepancy regarding 4G strength bars on display (all bars are ON) vs the web app where 1 or 2 bars are displayed which is the reality
  2. Is an update scheduled to support OpenWRT 19.07 release as it will allow the support of extra OpenWRT apps ?
  3. Band choice: it would be great to be able to choose or force 3G band when 4G bad. a good 3G is better than bad 4G

There is a bug in screen display and will be fixed.

I think there is AT command to lock to 3G. The following post locks for 4G but you can check Quectel command/
