This bin has it's problems. If I de-select every option possible, it will work OK for varying lengths of time. Enabling QOS, DNS Relay or Sharepoint seprately or together, the router will recycle at least 5 times per day. I have not been able to isolate the problem, but I have eliminated most variables on the software side, ie, there isn't anything on my or any other computer that would/should cause this. I am a home user with little IT training, so complex testing is out of the question for me. I do have all D-Link nics and and adapters, with the exception of my son's XBOX and a few I-Pod touches.
It does seem a re-boot of the modem and router helps the problem of recycling for a while, but there seems to be no pattern what-so-ever. I have checked the logs every time this occurs and there really is no pattern there.
