I have upgraded and looked all over and failed to find this feature. I need to force my router to pre assign local IPâ€™s based on the computer MAC address. I use multiple application that require local IP and i need to change this everytime i turn off and on a computer its changed my local IP based on which system accessed the router first. This was a great feature which came with my old SMC router. I also get random disconnected on my LAN computer (donâ€™t use wireless yet) for split seconds and immediate reconnect? Any clue?
