It's the WPA3 encryption. It needs to be set to WPA2 only for it to not shit itself.
EDIT: just checked, my router doesn't even support WPA3... I think it's typically the 5GHz network that upsets it, but I suppose I'll just continue resetting it for now.
I don't want to turn on my TV to listen to music (and Tizen only allows up to a certain quality), or use my nvidia shield, as it also turns on the TV via CEC.
Other platforms also don't support full quality like FLAC or Atmos mixes.
The thing is that the 2.4ghz wifi from the S90C (they both need to be on the same network for some goddamn reason to work in SmartThings) interferes with my DualSense gamepad.
