Internet "pauses" when using browser

When using a browser on a WiFi connected desktop connected to a Nighthawk R8500 the first webpage will immediately say the page can't be reached, and then within a couple seconds the page will automatically refresh and display the web page I was trying to access.  This happens with both Chrome and Edge.  It doesn't appear to do it everytime, but it has started doing it nearly everytime I open a new browser session and go to a new website.

When I opened routerlogin.net everything appears to be good, and it says Internet status is good.  I am getting the IP address and DNS address from the ISP.  Other IoT devices appear to be working properly, or as normal as they usually have. Speedtest shows speed to be normal.  All the Advanced Settings have green check mark except the guest networks which I have turned off.
