Your Chromecast or Google Home Might Be Screwing Up Your Wi-Fi

in a nutshell:

Essentially the Google devices are waking up from sleep and then sending way too much data at once to the routers, causing them to crash.

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 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.

Google has told 9to5Google that it is “working quickly to share a solution.” However if you’re finding your internet drops out anytime you interact with your Home or wake up your Chromecast, there are a few things you can do.

The most obvious one is to check with your router manufacturer for any firmware or beta firmware updates and apply them. You can also reboot your router to clear the memory and reset it after a data siege. And, if you want a very simple solution, you can just unplug the offending Google device, at least until router makers and Google roll out an official fix.

Say what - how the F are router makers suposed to fix the fact that a cast or home device is bombardin the network with up to a 100k packets?

How is that their responsibility to fix?

 

Mind you, a good router appropriate for a C4 system should be able to handle a few 100.000 packets without too much grief.

 

Nice find though.

My Pakedge network/WAP has been a bit flaky recently. I haven't done a ton to troubleshoot it, but I do have the new Chromecast. Sounds like this could be part or all of the issue.

Interesting.
