Multiple sources have stated that if your Wi-Fi is acting weird, your google home may be the one to blame.
Users have reported that Google Home and Google Chromecast devices may be messing with your Wi-Fi networks. Users who connect their devices to their Wi-Fi are at risk of having an unstable connection or their network going down.
Originally, it was thought that the instability was affecting the TP-Link Archer router series with a single Google device, the Google Home Max. But slowly, the issue is becoming evident in other Google devices such as the Google Home.
I use a NetGear router, so I have nothing to worry about. But that might not be the case as companies are saying the problem isn’t with the routers, it’s with the Google devices. This is what TP-Link says about this topic:
Following initial research and investigation, our engineering team is confident that they’ve determined one of the key origins of the issue. From what we have gathered so far, the issue appears to be related to some of the recent versions of Android OS and Google Apps.This issue stems from these devices’ “Cast” feature, which sends MDNS multicast discovery packets in order to discover and keep a live connection with Google products such as Google Home. These packets [are] normally sent in a 20-second interval. However, we have discovered that the devices will sometimes broadcast a large amount of these packets at a very high speed in a short amount of time. This occurs when the device is awakened from its “sleep” state, and could exceed more than 100,000 packets. The longer your device is in “sleep,” the larger this packet burst will be. This issue may eventually cause some of router’s primary features to shut down—including wireless connectivity.
So what can you do?
For now, the only known way to fix this problem seems to be just disconnecting your Google devices from the network or disabling cast functionality. A Google spokesperson said that they are working quickly to share a solution.
