Just some additional thoughts that could be contributing to your connectivity problems. See my post about DNS Relay settings at http://forums.dlink.com/index.php?topic=45143.0. Also, curious to know what your ISP provider connection idle timeout is set to, e.g. "Maximum Idle Time". Is the little Internet/ISP connection globe on the top of the DIR-827 colored orange before/during/after you experience these connectivity issues? Also, have you setup a GuestLAN on the Wireless? Just trying to determine the differences between the LAN segment that does not work and the WiFi segment that does.
