TP Link Archer MR600 does not support carrier Aggregation in India.
Hi Support , @Sunshine
I bought TP Link Archer MR600 from Amazon, it was not supporting Carrier Aggregation so got it replaced within a weeks time. New unit that I received is again not supporting carrier Aggregation. (ORDER PLACED on 2 September 2020 got it replace on 9 September 2020)
Problem is that TP Link Archer MR600 is not supporting Carrier Aggregation in Indian environment. My current service provider is Airtel, I can see 3 different band in different occasion, one at a time i.e. 1, 3 or 40
To confirm this issue, I checked this with Mobile phones, even the cheapest low grade Chinese phone is supporting Aggregation in my area.
I am still optimistic that TP Link will release proper software update specifically for India and fix this issue in a very short time.
One worst experience I would like to share about TP Link is that there tollfree don't even bother to respond to customer calls even calling them 100 times.
Details of my device:-
Firmware Version:1.2.0 0.9.1 v0001.0 Build 200511 Rel.44954n
Hardware Version:Archer MR600 v1 00000001
