You need to link your Stadia Controller to a screen before you can use it to play. If you want to play on a TV using Chromecast Ultra, you’ll need to use a linking code to link your Stadia Controller wirelessly. If you want to play on a PC or phone, you must use a USB cable to connect the Stadia Controller.
To let your Stadia Controller know which screen you want to play on wirelessly, you’ll need to enter a linking code for that screen. The linking code lets you easily change which screen your controller is linked to. Each screen will have its own unique linking code that will rarely change.
Enter linking codes from left to right, one button at a time. Linking codes are 4-5 characters long and consist of only Up, Down, Left, Right, A, B, X, Y.
Here is a sample of what a linking code looks like. The code for your screen will be different.
Note: Currently, linking codes will only appear on Chromecast Ultra. Linking codes for other devices will be available soon.
Note: If the status light blinks orange, it means the controller can’t connect to Wi-Fi. Open the controller menu in the Stadia app to set up the controller with Wi-Fi. If you need to change the Wi-Fi on your Chromecast, use the Google Home app.
I'm still not able to link my controller to the Chromecast that came with it. I'm using a Netgear Orbi wireless router. I've tried chromecast on 5Ghz and wired and it makes no difference. I'm able to see all devices connected when looking at my router including the controller. I can ping the controller and chromecast as well and they are on the same network. I'm not able to connect the controller to 2.4ghz band though. I've tried lowering the 5ghz radio strength and hiding the SSID and it still connects at 5ghz. In any event, my controller connects to wireless fine, but will not communicate with Chromecast still. It is very frustrating.
Anyone with a Netgear Orbi able to get this to work?
I'm not sure what happened, but my controller simply won't connect. Let me explain:
I made sure to connect my controller to my Wi-Fi network, as well as my Chromecast Ultra. Then, I entered my linking code with the controller. Well, it started blinking white for a few moments, and then it vibrated and blinked orange for a few moments. After that, it just turned off by itself and wouldn't link. The odd thing is that I didn't have this issue until after I played Stadia on my laptop with a USB cable.
I'm not sure what to do now.
