I have Whole Home system but it setup via Hard Wired Cable. I my older HR20-100 receiver in my Bedroom can see my HR21-700 in my Living Room but the HR21-700 can not see the HR20-100. My HR21-700 is connected to the Internet and it has the Correct Ip address,Subnet Mash and Default gateway but there is a setting at the bottom of setup screen called Link-Local and it has an address of 169.254.108.207 and it should be 192.xxx.x.xxx I believe so it matches my Network. How can I change that? I had never seen this number Link-Local before and my HR20-100 does not even have this setting even listed. Any ideas?
