- From Tp-Link: 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 recent releases of Android OS and Google Apps. This issue stems from these devices' "Cast" feature, which sends MDNS multicast discovery packets in order to 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 the "sleep mode", and could exceed more than 100,000 packets in a short amount of time. 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.
- From Linksys: I will keep the overall description short here, but this firmware incorporates a new WLAN driver that will help mitigate an issue that was discovered where Android devices coming in and out of sleep mode would crash the Wireless Network.
Hopefully Google is aware of the issue and will provide a patch soon.
A couple of issues...I have a Linksys EA7500 dual band router and I have all of my Google Cast Devices (2 Google Homes, 2 Minis, 1 Chromecast Audio, 1 Chromecast) on the 5GHz band and when I connect my Android phone's WiFi to the 5GHz band it will frequently lose the WiFi connection. However, it doesn't drop the connection when I connect it to the 2.4GHz band. As an experiment, I connected all of my Google Cast Devices to my 2.4GHz band and turned off the 5GHz band. That resulted in my phone again losing the WiFi connection. Additionally, often when I get home from work or wake up in the morning my cast devices will not be able to connect to the internet.
I recently heard about the MDNS issue caused by the Google Home Max and I am wondering if a similar issue is being caused by Google Home/Mini.
