Problem connecting to C7000

Is anybody experiencing connection problems with their C7000? 

I can't connect via the web interface or Genie after it's been running for a while.  If I hard reset it, then I can login just fine via both methods.  However, if it's been running for a while, I can't connect with either, requiring another hard reset when I need to get into the console.

Browsers reply with the page/site can't be found/reached and Genie shows the login credentials with a spinning wheel and eventually says that the device can't be found or is not supported.  Traffic flows great in and out as does the wireless.  It's just not letting me connect to log on.

I've looked for firmware updates, but there are none.  It's pretty frustrating to have to reset the darn thing whenever I need to make changes, look things up, etc..
