Hello. So this is my first ride with TP-Link when it comes to routers.

Chromecast.
Had massive problems with setting up my Chromecast that I got. It connected to the wifi then got stuck at updating but didnt update. After 5 min it said "Cannot connect to internet" and had me sign into the wifi again. My fix was to connect it to my phone and update it. And when it was done I connected it to my wifi again. Tried to install apps. Once again nothing happend. So connected it to the phone again. Downloaded the apps. And then connect to the wifi. Streaming to it works fine on the wifi. But I dont want to have to connect it to my phone everytime there is an update.

Youtube.
It takes for ever to load a video. And when it does in the middle of the video it gets all black. My guess this is where ads are ment to be playing. And this looks like a problem only on wifi. PS5, phones, chromecast. On PC it workes OK. Sometimes there are a loading screen for like 10 sec.

I'v seen some post about the chromecast but nothing has helped.
If someone knows if there is a feature or something thats blocking stuff.
I havent done anything to the router more then the basic setup.
