I have strange wifi internet problem, which started just recently. Connected to the wifi, maximum signal strength but no internet connection. All other devices connected to the same router, work without any problems. Changing the network, no change. I have 1ghz internet connection, so no bottlenecks. Switching the wifi on and off and rebooting the M11 few times gets the internet back.
Is there any Android setting for the internet to wake up with the wi-fi connected?
If you haven't already, consider assigning a static IP address to your M11 on your WiFi router.
