Nighthawk AC1900 Wifi Cable Modem Router -- Choppy and slow wifi

I have recently purchased said router and Comcast Xfinity high speed Internet with speeds "up to 400 Mbps".  Standing next to my Netgear modem/router, however, and measuring speeds with the Speedtest app on my mobile phone, I very rarely get speeds at 200 Mbps or over. Usually the test result is 170 - 180 Mbps.  (This is the 5G channel.) Is this something I should complain to Xfinity about?

AC1900 tells us nothing about your modem/router. AC1900  is not a reliable guide to model number. Many devices come with an AC tag, but it is essentially a label that Netgear, and other brands, attach to hardware to describe wifi speeds.

There isn't much that Xfinity can do. It is not responsible for your wifi signal. As long as your Netgear modem/router gets 400 Mbps, Xfinity has done its bit.

You will never get wifi speeds to match wired speeds. That's down to physicist. For many mobile devices, 200 Mbps is pretty good.

Does your mobile phone get much faster wifi speeds anywhere else?

It might help to do a bit of background reading on what you can expect from wifi.
