However, the Chromecast and a range of other routers including ones by ASUS, Linksys, Netgear, and Synology are also being affected. And while TP-Link has released new firmware for the Archer C7 which eradicates the problem, users of the other routers are still being affected.

While these are normally sent every 20 seconds, when a device is awakened from Sleep a large amount of packets can be sent in a very short space of time. And this can interrupt your router’s ability to function.
