Intermittent DNS resolution issues with Netgear modem + Google Nest Wifi router

@Comcast_Support  Hello, I am having a very similar issue to the one described in this post: https://forums.xfinity.com/t5/Your-Home-Network/Consistent-Comcast-DNS-Issues/td-p/3184898

I saw several reommendations to PM Comcast_Support for additional assistance.

Once or twice a day, I will notice my iPhone, or the kid's Chromebooks having trouble resolving websites. It gets stuck on the resolving host step. After a few seconds or minutes the problem goes away and sites start loading again.

While the problem is happening, DNS resolution (nslookup) fails, but direct pings to IP addresses work.

I have tried various combinations of DNS settings in the Google Wifi router (ISP defaults, 8.8.8.8, 75.75.75.75, etc.)
