ARP or Static IP (SOLVED)

[johngc]

I am a bit confused between the ARP or Static IP options and not sure which one is best for my circumstances. I have set my router to have an IP address of 192.168.1.1 and have the dynamic range from 192.168.1.100 up.

I would like to set things like a WAP, Switches etc as static IP's from 192.168.1.2 , 1.3 , 1.4 and so on and almost group my devices by IP address (home automation, media devices etc) and then leave the 1.100 and above for the devices that join as guests or that I don't really need to keep track of the IP address.

With my previous router, it was easy just to select a device, give it a static IP and then reboot. What seems to have happened now is that some devices have kept their old IP address from the previous router (and now appear in the ARP table) and some have not.

As it seems a bit of a palaver to individually record each MAC address to assign a fixed IP, I want to make sure I get it right.

Should I be going to Configuration > Lan > then add a static IP per device or should I go to Advanced Settings > Static ARP and add an IP per device?

(PS it would make life so much easier to have a dropdown list of the MAC addresses like there is in the Configuration > Security > Time Restriciton option )

Add the MAC and IP address under 'Configuration >> LAN' in the middle of the page there is a 'Static IP Lease List' click on the 'Add' then add the MAC and IP address outside the DHCP range. Once done restart the client

Thank you - that did the trick

Hi - just found this solution,as I was also struggling to find out how to fix IP addresses for my devices, but when I enter the IP address of the device I want to allocate a static IP to, having checked on the DCHP leased table to make sure its right, the setting will not work - I get an error message IP Address Invalid. But it cant be invalid, it is there in the DCHP table!


Can anyone please explain what I am doing wrong?

many thanks

You must use a IP address outside the DHCP range to avoid IP address conflicts (Default DHCP range is 192.168.1.100 ~ 192.168.1.199, so try using 192.168.1.200 for example)
