Hi @DaveyJakes,
I've got Google Fiber but haven't used their Network Box since before Stadia launched, though I do recall some weird Wifi issues from when I was using the NB. For a while I had a Google Wifi router node downstream from the NB and that was more stable and consistent (despite the double-NAT). Then I opted in to the "bring your own router" program so I could plug the Google Wifi unit directly into the Fiber Jack and ditch the NB completely. And then I upgraded to the 2 Gig plan and used that Gateway + Mesh extender. I'm back on the 1 Gig plan but still using the 2 Gig Gateway with my Google Wifi nodes downstream from that. (Now I wish that I could switch back to the own-router setup but that's apparently not an option after trying 2 Gig.)
All that is to say that I think their NB is kind of garbage, and you may want to consider bringing your own router to Google Fiber. That would likely be your easiest fix for this issue, and it will provide you with additional control to further improve your network.
If that's not an option, you might see about splitting your 2.4GHz and 5 GHz networks to two separate SSIDs (if you haven't already) and connecting both the controller and TV to the 2.4GHz network (since you had poor performance with the 5GHz one). 5GHz Wifi is capable of faster speeds under ideal conditions, but the higher frequency doesn't travel as well through walls and other obstacles. The signal strength can drop off rapidly, and a weak 5GHz network will actually perform worse than a stronger 2.4GHz one.
