C6300 loses all connections.

I purchased my C6300 about a year ago.  During that time about once a month I lose internet access.  Cycling the power on the C6300 restores the connectsion.  I have screen shots of various management screens, one that shows the the internect connection is down.  When in the failed mode, I can't not access the management port remotely, but I can access the management port via WIFI.  However many of the screens take a long time to display, for example the main status screen takes several minutes to display, where normally it pops up in seconds.  I've attached a file with my screen shots.
