Update 1/16/2017: A spokesperson told 9to5Google that the company’s “team is working quickly to share a solution.”

If you started experiencing Wi-Fi connectivity around the time you picked up a Google Chromecast or Google Home speaker, you’re not alone. As recently detailed by engineers at TP-Link, there’s a potential corollary between Google’s “Cast” protocol and the instability of wireless networks over which it’s used.

Along with new beta firmware for the TP-Link Archer C1200 router (hardware versions 1, 2, and 3), TP-Link engineers published a full explanation of the Google Cast bug they discovered. phones and tablets and Cast-enabled Google apps such as YouTube, Google Play Movies & TV, and Google Photos maintain an active connection to Google and Google via what are called MDNS packets, or “multicast Domain Name Server” packets. MDNS resolves the hostnames of (i.e., the network names assigned to those ) to IP addresses, and is commonly used on local networks that don’t have a DNS server. They’re normally sent every 20 seconds or so, but when some Google Cast-enabled go to sleep, they continue to queue new packets to send until woken up and unlocked. This can cause surges of more than 100,000 packets in a short window — the amount of packets sent is directly proportional to the amount of time the device stays asleep. That causes connectivity issues, of course, but can also crash Wi-Fi routers and affect a number of their core services. The only way to fix it is by rebooting the Wi-Fi router.

The bug’s not limited to Archer C1200 owners. TP-Link Archer C7 users have reported the same crashes, as have owners of routers from Synology and Linksys.

If you’re suffering from the issue, TP-Link recommends disabling the Cast feature on your Android and/or tablet for now. Alternatively, it recommends disconnecting all Cast-enabled devices from your Wi-Fi network until Google issues a fix.
