sonnyyu, thank you so much for all your time. Looking around the forum I can see that you are very helpful to people on the board. Now that I can connect to the Yun in the field and have another one to test with, I am implementing the DHCP fix on all of them... I think that is the issue. When we were talking before I was unable to fix the remote located one. I was a bit confused on DHCP... I know what DHCP is, but wasn't thinking straight. Even though the router sets up a 'static' IP for the Yun, the Yun is still behaving as DHCP from its perspective. I will report back to confirm this. It's glad a fix was found (the link you provided), but it's frustrating that OpenWRT/Yun was released like this with such an obvious problem on the LAN. Hopefully not too many other people consume so much time by dealing with this issue.
