Google Chromecast Devices Are Messing With WiFi Connections

Google Chromecast Device

Chromecast devices have been interfering with WiFi connections, according to a latest report on connectivity issues published on January 16, 2018.

Users have reported to lose WiFi connections when connecting Google devices with the ‘Cast’ feature, such as Chromecast and Google Home devices. Initially, it was found that TP-Link Archer C7 routers were the only ones affected by the issue, however, subsequent reports have noted that ASUS, Linksys, Netgear, and Synology routers were also impacted.

TP-Link has issued firmware fixes for the problem and explained in a statement that the issue lies in how these devices send information to routers when they’re awakened from their sleep states. Typically, devices like this send MDNS multicast discovery packets to routers at 20-second intervals in order to keep a live connection.

“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.” said TP-Link.

This overloads the router and can affect your wireless connectivity. Rebooting is an option, however, doing it over again can would be a task.

A Google spokesperson told us, “We’re aware that a small number of users are having issues and our team is working quickly to share a solution.”
