I've recently purchased Cisco Linksys E900 Wireless-N300 Router for my FTTH connection, suprisingly all the push notifications are getting stopped and sometimes they get delivered sporadically, but when I open the app I can see that my phone is connected to internet e.g. when I receive an email I normally get a push notification from Gmail app, this notification will not be delivered when connected to Cisco router, however if I open my Gmail app I can receive emails, the same is the issue with all other apps on my iPhone 5, and another issue is I cannot use Ookla Speed Test app when connected to Cisco router, however when I switch off Wifi and connect to my cellular network all the push notifications and Ookla Speed Test will start functioning. I've tried disabling fire wall in the router, but it didn't help...please help me to resolve this issue.
