A few weeks ago there was a problem related to home WiFi and Google Cast compatible devices. Many routers collapsed because mobile phones were constantly trying to access the Chromecast and the network was blocked. I had no easy remedy since it was Google itself that had to correct this problem.
Days later it was announced that the solution would be available on January 18 and an update of the Google Play Services was made available to the users that lightened the constant load caused by the Chromecast and the routers could work correctly.
To date, the recommendation has been to restart the mobile phone and update the router to the latest firmware version. D-Link, Netgear, Asus or Synology among others presented new updates to their software to alleviate this problem.
But the bug was still there until today. Google has already fixed this problem that affected Chromecast, Google Home or Nexus Player. The solution will be automatically distributed to all Android devices with the latest update to Play Services version 11.9.75.
Those affected can download it manually or wait for the mobile to update. If you are not aware of these problems but your WiFi lately does not work properly, you know that with this patch, which will be offered next to the latest version of the Play Services, maybe the faults will disappear.
