According to Google, “Starting this week, you can now use the Stadia Controller to play wirelessly on your laptop and desktop. You no longer need to connect your Stadia Controller physically to your computer to play your favorite games. You’ll be able to link your Stadia Controller and Stadia.com through your Wi-Fi network and play without a USB-C cable connection.”
While PCs might come with multiple ports, going wireless makes it ideal for gaming on laptops, which these days might come with less ports and might come with full USB-C ports, so if you have some ports that are already in use, then this will at the very least keep some of them free for other use.

It’ll also make it easier for you to switch between devices like your computer, your phone, tablet, or TV. These changes are expected to begin rolling out this week, so do check it out if this has been a feature you’ve been looking forward to.
