This is a last resort, in case one of you has found a magic solution. I have DIR-655, 1.33NA. Recently, I noticed the clock in the router was off, so I wanted to correct it. Each and every time I go through the steps to reset the clock, using time server or clone computer time, or manual reset, after the save settings and reboot of the router, i find the router still displays the wrong time, and frequently reverts itself to a time on Feb 22, 2012. Same problem for trying to reset the DST settings, turning automatic time from server on and off, changing the time server polled. Additionally, I have forced the router to factory settings and rebuilt all of my configuration no less than 4 times.
So, since I recently had to trade out the cable modem because Cablevision fried it with their 'system upgrade', I'm also wondering if the same shenanigans also damaged the router.
Anyone?
