Gateway upgrade

I've been getting  more than a few network quality issue warnings from my videoconference software lately as well as difficulty streaming. We have 14 devices, TVs, computers, gaming system, Alexa units, etc. . There are two of using computers to access or connect with work.

We have Comcast 200MB servie using the Ariss TG1682G gateway. Comcast has reset the modem a number of times and no improvement. I am considering replacing my Comcast provided modem/router with a new Arris SVG2482 AC model. Will that provide a quality improvement?
