Google has started rolling out a patch that will prevent Cast-enabled devices from killing your WiFi connection. The patch is rolling out to Android devices as a Google Play services update. Apparently, they sometimes beam too much data at a very high speed in a very short amount of time, slowing down and even disrupting WiFi connections when you try to Cast to Chromecast, Google Home and Android TVs. It'll probably hit your device soon if it hasn't yet, but its APK is now available for download in case you're worried that the bug can affect your binge-watching session this weekend.
