According to a TP-Link engineer who investigated the problem, the crash is caused by Google's device sending hundreds of thousands of data packets in a short amount of time, a traffic spike that can crash routers commonly found in your home.
The reports of issues on home networks has been reported on the Google Product Forums, as well as on the forums of router manufacturers Linksys, Netgear and TP-Link. Secondly it suggests disabling the Cast feature on your Android device to mitigate the issue until an update is issued to permanently fix the problem on the Google Home and other systems.
Google products have had their history of disrupting WiFi connections, with the first reported device being the relatively unknown Nexus Player. But unfortunately, the recent update has caused the device to send more packets than usual, reaching up to over 100,000.
The issue appeared isolated to networks with a Home Max and TP-Link Archer 7 router. The result? A stable network that has had no dropouts or issues since. "Both of these firmwares will eventually make their way to our update servers for regular download, however [we] decided that a month of this issue is long enough for us to post this for all of you that have been following this in the community to download and use while we go through our final QA checks that are required before putting it on the update server", Linksys said.
One anonymous user in the forum started a thread after noticing that their Wi-Fi network had started dropping out with alarming frequency upon returning home with an Android device.
Just as technology manufacturers and users are still reeling from the threat of Spectre and Meltdown, a new bug is reportedly affecting Wi-Fi networks. We had issues at INQ Towers about a year ago where all our connectivity ceased and could only be restored by unplugging all the Chromecast devices. "Also, please confirm the firmware version your router is on", the expert said. Yet, it seems that other products from the search firm also exhibit the same problems with user's wireless routers.
If left alone long enough, TP-Link warned, the burst will fill up the router's memory and leave a reboot the only option to restore connectivity. Some routers won't even connect at all but only for a while.
