On a related topic. I have a really weird problem in my house where I'm about 20 feet from my TV trying to use my PS5 DualSense connected to a Google TV device connected behind the TV. It uses Bluetooth, which is also 2.4GHz, and the issue I'm having is that the dongle behind the TV is really impacting my controller connection and making playing games over PS Remote Play completely impossible. I even have the GTV device hard wired with an Ethernet adapter, as is my PS5. This can't really be a range limitation can it?

Bluetooth is pretty low power, but without the TV in the way, that range should be no problem at all. Problem is that a lot can block it physically and drown it out in RF noise.
Most TV's probably have a thin, but solid aluminum plate in them for structure that could indeed block BLE and be causing the issue. Ironically, this is one RF case where metal studs would actually be helpful.
For comparison, I fly a paramotor and use Sena Bluetooth mesh for comms, and just our heads at any distance are enough to block it if we're on the wrong side of each other. Motorcyclists on the other hand don't often have this issue since there's other vehicles and stuff to bounce their signals around.
What might help if that's the issue is something reflective like foil mounted somewhere that can see both the controller and the GTV device. I'd also try to make the reflector slightly/roughly parabolic-ish (kinda shallow as to not make aiming difficult) pointed at the GTV device. You can hide the reflector behind and/or point it through anything RF transparent like wood or plastic.
Another possibility is other 2.4ghz noise— You could try turning down 2.4ghz transmit power on your AP as a possible quick fix. Of course if you haven't, make sure anything that can be on 5ghz, is.
Edit: Note that a reflector will also reflect noise sources at the GTV device.
I've also had issues with poorly shielded HDMI interfering with 2.4ghz in close proximity, so even just jostling things around behind the TV a little or using your best shielded HDMI cables there could help some.
Debugging RF can be tricky and frustrating, but I hope one of these tips helps either you or maybe a passer-by one day. :)
Happy new year!
