Wi-Fi cutting with "Google Home" and "Chromecast"

　If your home Wi-Fi is not in good shape recently, "Google Home" or "Chromecast" may be the cause.Android Police reported on January 13 that the smart speaker "Google Home Max" had several cases where the TP-Link "Archer C7" router was disconnected.

　Later, it was revealed that other devices were also affected by the bug.In addition to other Google Home speakers and Chromecast dongles, other models of other models of TP-Link, ASUS, LinkSys, NetGear, Synology routers, etc. have occurred.According to a comment on Reddit, the users of Google Wifi have also had some effects.

　TP-Link explains that the "Cast" function causes problems.The CAST function allows you to communicate with smartphones, Google Home speakers, and Chromecast devices.According to TP-Link, this is "by transmitting an MDNS multicast detection packet to detect Google products such as Google Home and maintain a live connection with it."Packets are usually sent every 20 seconds.However, since the recent firmware update, the reason is not explained, but when the device starts from the sleep state, excessively many packets (it may exceed 100,000) are sent to the router and the function is made.It is said that it will stop.

　According to TP-Link, the longer the sleep time of the device, the greater this packet burst.

　Google has not yet been revised, but the company told 9to5 Google that it is "working to provide solutions quickly."US CNET asked Google to comment, but did not get an answer.

　TP-Link has released a formal patch of this bug for most of the affected versions of hardware and a beta firmware for the Archer C1200.

　No formal solution has been provided to other users.The best workaround from Google or Router manufacturer to the firmware patch is issued, cut off Google devices when not in use.This method is valid for Chromecast, but unfortunately, in the case of Google Home speakers, it is substantially unusable until the patch is provided.
