LTE Bands: Band 1, Band 3, Band 8, Band 40
I'm using the frst beta firmware to manually enable carrier aggregation on MR600, however I've come across the following issues:
1. Manually selecting Band 3 and Band 40 enables the 4G+ mode, but the bands don't remain aggregated indefinitely. Sometimes it remains aggregated for an hour or more while sometimes it remains aggregated only for a couple of minutes. Once the aggregation is lost, the router switches back to Band 40.
Why is this happening? Is this an issue with the router or with the cellular tower?
2. My ISP supports intraband aggregation for Band 40, but the MR600, even after manually selecting both bands to Band 40 doesn't aggregate them. The advanced page shows that the router is still using single Band 40. The possible CA combinations on the first page shows that intraband Band 40 aggregation is supported on the MR600.
Again, is this an issue with the router? My iPhone always aggregates Band 40 which gives me the best speeds, so I'm sure that the tower is capable of allowing intraband Band 40 aggregation.
I'd really appreciate if someone can help me out here.
