Brand new TP-Link Archer AX5400 Pro has very slow response on it's own interface web pages, buffers and drops video streams from twitch and you-tube, drops wireless connections repeatedly. I only replaced the router, the modem and ISP are the same. I get 348 Mbps on speed tests.

I had this problem after upgrading firmware, connecting to tether, and after reseting to factory and not connecting tether.

Is this router no good, or is there some setting i need to set to work well with Spectrum ISP? Not that I can find most of the normal router settings with in all these pages that take 2 minutes to load.

Returning this router to the retailer next week if I can't get back to decent performance.

Very disappointed.
