After a couple hours of normal functionality, where both SSH and Yatse works perfectly, both will suddenly drop. This has been consistent behavior over the last couple of months.
When this happens, the following are all true:
The Pi2 is still online, it will continue to play both local and YouTube videos. Using a connected keyboard I can also search for other YouTube videos and they play just fine.
The router lists it as connected to the wifi.
Pinging it’s IP returns “host is down”.
Attempting to connect over SSH times out.
Yatse considers it offline.
Have any of you had similar problems? I am using the official raspberry pi Wi-Fi dongle.
