Google Home or Chromecast Could Cause Your Wi-Fi to Crash

If your Wi-Fi is not performing as well as it should, chances are it is affected by Google Home or Chromecast. Luckily, there is something you can do about it.

If your Wi-Fi is giving you troubles, maybe you needn’t look any further than your Google Home speaker or Chromecast.

Lately, there have been multiple reports of a Google Home Max speaker crashing TP-Link Archer C7 routers offline.

These reports were followed by reports of other Google Home speakers and Chromecast dongles knocking additional TP-Link router models and routers from Asus, Linksys, Netgear, and Synology.

Additionally, a number of Google Wi-Fi users have also complained that they have been plagued by the same problem. 

In response to these claims, TP-Link issued a statement saying these problems are caused by the Cast feature which allows Google Home speakers and Chromecast devices to communicate with your phone. 

This feature, TP-Link said, sends an MDNS multicast discovery packets to “discover and keep alive connection” with Google products such as Google Home.

According to TP-Link, these discovery packets are typically dispatched in 20-second intervals. However, a recent firmware update is causing these devices, when exiting a sleep mode, to occasionally send an overwhelming number of packets (as much as 100,000, in some cases) to the router, causing it to crash.

TP-Link said the reason for this has yet to be explained, but noted that the longer the device sleeps, the larger this packet burst will be.

With that said, what can one do to keep their Google Home or Chromecast from killing the connection?

Google has yet to release a fix, although the company has said that it is working to solve the issue.

TP-Link, however, has already released official patches to counter the effects of the bug for most of the hardware versions affected, as well as a beta firmware for the Archer C1200.  Users are recommended to log in to the admin panel for their routers and check for any firmware updates.

According to TP-Link, Archer C1200 users will need to download the correct beta firmware for their computer and follow the instructions as listed on the company’s web page.

The company also advises that installing the incorrect firmware could damage the device and nullify the warranty, so be sure to double-check before downloading the firmware for your device.

For the rest of you that are experiencing this problem, there is no official solution just yet, but Google has pledged to introduce a fix in early 2018.

According to Google, this fix is rolled out in the form of an update to Google Play Services, so be sure to check on the Google Play store from time to time to get a hold of it as soon as it comes out.
