Hello,

I've recently purchased an MR600 to upgrade my existing MR200 - I've not been able to enable Carrier Aggregation and therefore 4G+ on the router. I'm on the Three network and 4G+ works when CA on a mobile device, but even when two compatible bands are selected as per the TP-Link website (B3+B20), the router only uses B3 and operates only on 4G LTE, even with 100% signal strength.

Firmware is up to date, signal strength is at 100%.

I've not seen any solutions from other threads.

Thanks for your help in advance!

Dan
