Chromecast Causing Wi-Fi Issues For Users

Adjust Comment Print

Apparently Google's smart devices are overloading some routers and causing network problems.

Unfortunately, it seems as though TP-Link routers are not the only ones affected by the issue. It's a weirdly specific bug, but TP-Link has reportedly pointed the finger at so-called MDNS packets that keep a live connection with Cast devices. But unfortunately, the recent update has caused the device to send more packets than usual, reaching up to over 100,000. That causes connectivity issues, of course, but can also crash Wi-Fi routers and affect a number of their core services.

Router manufacturers like TP-Link, Linksys and Netgear have acknowledged the problem and issued firmware updates, and these updates will act as mitigation until a patch for Cast is issued by Google itself.

But when your smartphone - or another connected device - is put into a sleep mode, this packet transfer stops.

TP-Link issued a fix, but as the issue developed it began to look like it originated from the Google device rather than the router.

Speaking about the same, Twinkle told the leading daily, "It's not pleasant for both [the parties] and will impact both". In the case of a single release, Padmaavat could aim at 4,500 screens and Padman 3,500 screens.

One anonymous user in the forum started a thread after noticing that their Wi-Fi network had started dropping out with alarming frequency upon returning home with an Android device. The company said engineers are now investigating the matter and indicated detailed feedbacks sent in by customer will help resolve the issue fast. When they did awake from their slumber, they flooded a WiFi router with huge amounts of data packets at a "very high speed", which would overwhelm certain routers and cause the disruptions.

A company spokesperson told 9to5Google that its team is "working quickly to share a solution". The result? A stable network that has had no dropouts or issues since.

It's not clear whether the problem stems from a flaw in Google's hardware, or whether it's the result of a broader software issue.

In the meantime, consumers who think they may be having issues related to the packet bursts are urged to check for firmware updates for their routers.

Generally, you will need to perform a reboot to release the memory to solve this issue. Finally, simply unplug the Google device until a fix has been issued.
