I contacted D-Link Support and complained about my router reboots and before they responded I tried the beta version ftp://ftp.dlink.com/Gateway/dir655/Beta/Firmware/dir655_fw_132b04NA_beta01.zip then did a factory settings default and disabled securespot. My router is about 95% stable at this time.
This was Supports response:

Based on the description in the email, we would like to know whether you are facing drops with wired or wireless.
