mac address conflict
I have started getting a message in my readynas duo logs which reads mac address C8:2A:14:5B:72:EA claims to have our ip address 192.168.0.3 duplicate ip conflict likely, it seems that it is confli...
The error means that you have two devices on your network trying to use IP address 192.168.0.3 (it is not a mac address conflict).
If you are using some (or all) statically/manually assigned IP addresses, then you likely accidentally created the conflict by assigning a duplicate address.
Assuming all your addresses are automatically assigned by DHCP - do any of your devices go into standby? If they go into standby for an extended period, than the router might be releasing/reusing one of the addresses. In any event, turning all your devices on and rebooting the router will cure this problem (at least temporarily).
You might also take a look at the DHCP lease times configured in the router. This should be longer than the normal standby periods you use.
