I am planning to upgrade from TD-W8968 and I've had a very good experience with it for the past 8 years. 

I need a router that doesn't compromise on features I've been using on it like SNMP, Fully manual bandwidth control including guest network, USB flexibility, etc. For the upgrade I want it to be dual band MU-MIMO with beamforming, Smart Connect, IFTTT/Alexa ready, Onemesh support. 

I had shortlisted Archer A6, C7, A9 but all of those compromise on one thing or the other from my requirements. None of them have SNMP, and fully manual bandwidth control.

I need an affordable router with a throughput of somewhere between 1300 to 1900 Mbps.

Please suggest a router to fulfill all my requirements and if there's none out there, consider this a request for such a Wifi router.

I, being a network engineer, prefer to be in control of my network so I recommended TP-Link routers to all my clients for home and small office usage but lately TP-Link has not been making the kind of products that made me recommend it to everyone.
