It may be helpful to describe your setup.
Hard wired network; there are multiple connected items all functioning properly (two AppleTV's, three wired desktops, wii, two wireless laptops, two iPhones, one iTouch). No connection issues with any.
HR20 is wired thru 5-port ethernet switch (an AppleTV is functioning on this same switch). Have also tried with isolated connection to router.
Have tried "advanced settings" with both reserved and assigned IP addresses. Sub-net, Gateway, and DNS all the same as all other equipment which is connected to network & internet.
Oddly, though the HR20 indicates a MAC address ending in 67, the router indicates the MAC address of the recognized HR20 as ending in 68. Have tried specific IP reserves using all combinations of MAC's and IP's to no avail.
Though the HR20 shows up in the DHCP client list, I am unable to ping it; all other equipment can be pinged.
