I sometimes experience those little bugs off and on, but they go away after a few days. For example, my WiFi would keep disconnecting and then reconnecting (though it wasn't my modem, because the internet on my laptop was fine); but that issue went away after a few days.
Have you tried rebooting your device and/or turning off your WiFi connection for a time; then turning it back on again? What about other devices in your connection area - are they working well under the WiFi connection?
