I am experiencing a problem with my DIR-601 router.  At random times throughout the day, the router will automatically reset itself.  The problem seems to be the worst during the morning, resetting every 5 minutes.  Later on it happens about every 30 minutes.  Is there some setting I could switch that would prevent this?  It is very annoying and will probably result in me buying a different router if I cant fix this.  
If anyone has any suggestions that would be very appreciated,
Thanks!
Matt
