I tried everything just to get 4G+ LTE Carrier Aggregation but it always going back to single band.

I ONLY GET 4G+ LTE IF I REBOOT THE DEVICE BUT AFTER 10 TO 30MINS IT WILL DISAPPEAR.

THIS IS MY CONNECTION MOST OF THE TIME, IT ALWAYS CHANGE TO SINGLE BAND SINCE I SELECT AUTO MODE.

I tried everthing, Band Locking, 4g Only Mode, Select 2 Bands and all, I also follow the image below and still no hope.



THE ARCHER MR600 V3 IS A COMPLETE HOKUM

instead of fixing the issue they release V5.
