Wireless connection drops on the 57th minute of every hour

I have FIOS.  For many months, if not a year, (if not longer) the internet connection drops on the 57th minute of every hour.  On every device in the house.  The Wireless Connection disappears completely as a source on my laptop, my iphone won't load, and my wireless radio loses connection and the radio queue resets.  It's not that all of these are running at the same time, sometimes it's only one device.  But the fact that it is reliably, and always, on the 57th minute of every hour is quite noticable.  Any help appreciated!
