Help Assigned IP address being Ignored

[Sean Rhodes]

I have the ASUS RT-AC3200 router running 380.65 (latest) firmware and recently I have started have issues with a couple of TP-Link power line adapters changing their IP addresses, even though they are out of the DHCP range and have reserved IP addresses tied to their MAC addresses.

I cant seem to figure out what's going on. My DHCP range is 10.0.1.101 to 10.0.1.255, and the assigned IP addresses are/were 10.0.1.46 and 10.0.1.48, each tied to its MAC address.

For no apparent reason I could not login to either device, when I used the TP-Link power line detector, it found them, but I could see the IP addresses were changing every 3 mins or so, and the range was all over the map, it would be 10.0.1.159 then 3 mins later 10.0.1.19 etc.

I have a MacBook and Apple TV on the same network, that have no issues, its tied solely to the power line adapters and I cant find anything on the web about this. Does anyone have any ideas? The only thing I can think to try is to turn off DHCP and set everything to fixed IP's to see what happens, other than that I'm stuck

The only thing that comes to mind is that there is another DHCP server on the network. It seems unlikely that your adapters could somehow have connected to a neighbours network, but if you haven't changed the default Network Name (NMK) from "HomePlugAV" it's probably worth changing it now.
