It appears the Google's line of Cast-enabled devices has been causing issues with wi-fi networks. Everything from their Chromecast to their Google Home Max seems to have an issue where it floods networks with packets when they come out of their respective rest modes. When the Cast-enabled device wakes, it could send as many as 100,000 packets or more before letting the network go depending on how long it was asleep. As the packets flood the network, they essentially slow down connectivity for any other devices trying to connect to the point that they may as well be dropped.
Router manufacturers including well-known brands like Asus, Netgear, and Linksys were flooded with complaints from customers over the problem and are working on firmware updates to solve the issue. TP-Link has also stated that users can reboot the affected device(s) in order to release its memory or simply deactivate Cast on Android-enabled devices.
Speaking to Engadget, a Google rep stated: "We're aware that a small number of users are having issues and our team is working quickly to share a solution."
In the meantime, consumers who think they may be having issues related to the packet bursts are urged to check for firmware updates for their routers.
