Recently I started having problems with my HR44. It would not connect to the internet anymore. I changed cable, switches, rebooted router, etc. It was giving error codes and could not connect to the internet. I could not ping it from my LAN. I called Directv tech support. They ran some tests and deemed it broken and sent me a new HR54. When I initially hooked it up it didn't go smoothing. It also could not connect to the internet. I rebooted the HR54 and router and it finally connected. Both HR54 reports an IP address of 192.168.1.21 and has a LINK Local address of 169.254.8.237. Running an IP address scanner (Fing) on my iphone it finds the HR54 at 192.168.1.21 like it should. However my Netgear router reports the address using the LINK Local address of 169.254.8.237. After several hours or over night the HR54 looses internet connection and won't connect to my hr24. Also Fing also reports that the HR54 is now missing. The router still shows it as a connected device at the LINK Local address. Does anybody have an idea what is going on or how to fix?
