MR600 - CA with qualcomm snapdragon X12 Modem
I see that MR600 houses a powerful Qualcomm 4g LTE X12 modem, which supports 4XM MIMO up to 256-QAM.
But, in the real-world when I connect MR600 it doesn't establish an LTE CA connection. Whereas a cheap android phone is able to establish a 3CC CA connection.
I own an MR600 and am evaluating whether to switch to a Huawei router for CA support. So, I went to evaluate the hardware specs and found MR600 has Qualcomm X12 which is capable of higher orders of CA.
Why is tp-link under-utilizing the router hardware and is giving a bad customer experience? This is just a bad return of investment for the router owners. Why are you not paying attention to numerous requests on this forum about MR600?
For everyone's reference, below are X12 capabilities as per Qualcomm's website.
