I am facing abrupt disconnections in the internet from my wireless network.  If multiple devices are connected one of the devices suddenly gets disconnected from the internet. When I check on my windows laptop against my SSID the follow message is shown "No internet, secured" and in android it shows " connected" no internet, this is for both frequencies 2.4 and 5 Ghz. But my windows laptop gets disconnected more often, and this happens at least twice a day. The fireware is upto date.  to resolve the issue I have to reboot the router along with my windows laptop to get  the "connected, secured" message against my SSID and internet access , any pointers  to resolve this will be of great help
