nighthawk r8000 connection issues

I'm having a problem with Google fiber and a Netgear nighthawk r8000 where (as the title says) nothing loads right or connects the first time and I have to refresh or wait for pages to auto refresh to actually work. For example, if I Google something and click on a website it will either say "this site can't be reached" or it will only load text and no pictures until I refresh a couple times. It also happens when I try to open things like steam where it won't load and I'll have to open and close steam a few times before it works. And if I try to join a discord voice chat it connects and disconnects and reconnects again.

I'm using Google fiber with the Netgear router that I mentioned and it feels like the problem happens more frequently on Ethernet than wifi.

Does anybody know what's causing this or how it could be fixed?

edit: the router is connected directly to the fiber jack in the wall and not going through the provided google fiber router.
