Update: Google has posted a support page for this issue earnest a fix tomorrow (1/18). The page says the issue is singular to “People with an Android phone and a Chromecast built-in device (such as a Chromecast or Google Home device) on the same Wi-Fi network” and that a fix will be rolling out around Play Services.
The strange story is below.
Users on the Google help forums and Reddit are stating that Google Home and Google Chromecast inclination are causing issues with their Wi-Fi networks. Users contend hooking up these Google hardware products leads to an inconstant Wi-Fi network or a network that goes down entirely.
The instability was creatively suspicion to impact the TP-Link Archer router series with a singular Google device, the Google Home Max. The issue has been solemnly creeping out to other devices, though, with the Google Home, Google Home Mini, and Chromecast apparently having identical issues. TP-Link was singled out since it’s a renouned router brand.
TP-Link released a beta patch for the Archer C1200, but the company came to the end that the issue isn’t with its routers. In a support article, TP-Link writes:
Following initial investigate and investigation, the engineering group is assured that they’ve dynamic one of the pivotal origins of the issue. From what we have collected so far, the issue appears to be associated to some of the new versions of Android OS and Google Apps.
This issue stems from these devices’ “Cast” feature, which sends MDNS multicast find packets in sequence to learn and keep a live tie with Google products such as Google Home. These packets [are] routinely sent in a 20-second interval. However, we have detected that the inclination will infrequently promote a vast volume of these packets at a very high speed in a brief volume of time. This occurs when the device is awakened from its “sleep” state, and could surpass some-more than 100,000 packets. The longer your device is in “sleep,” the incomparable this parcel detonate will be. This issue may eventually means some of router’s primary facilities to close down—including wireless connectivity.
For now, disconnecting your Google products from the network or disabling expel functionality seems to fix the issue. A Google orator told Engadget, “We’re wakeful that a tiny series of users are having issues, and the group is operative fast to share a solution.”
