I guess you are inquiring Carrier Aggregation function? MR400 doesn't support Carrier Aggregation, only MR600 supports it, please check the product specifications:

@Kevin_Z Could you guys allow Carrier Aggregation support on "Vi India" it uses B1, B3 combination....
My mobile device aggregates successfully... But TP Link Archer MR600 doesn't seem to aggregate.... I even tried locking bands on beta firmware too, no improvement...
I kindly request you to allow 1,3 CA at firmware level
Thanks in advance!

Hi, actually selecting the band manually is to inform the 4G base station the band we would like to use, but it is decided by the base station whether and how the bands will be aggregated. We are unable to force them to work on specific band combinations.
It is recommended to choose the band combinations with better speed and stable connection, if the signal is not very stable, you could also leave it on Auto so that it will change to other band automatically when specific band has weak or no signal.
