Some sites recommend to restart the router device, and sometime it works.
Instead of every time restart the router to solve the Wi-Fi problem, it worked for me:

Inside the router configuration (e.g., accessing the IP 192.168.0.1), change the "Group key update" value from 0 to 30 seconds, under the "Wireless > Security" configuration, right below the WPA-PSK/WPA2-PSK item.

Router: TP-LINK TL-WR740N / TL-WR740ND.
