Re: conflict IP address after power failure

In my RAX45 router, I reserved some IP addresses for specific devices while leaving the others to be determined by DHCP. However, after a power outage, a reversed IP address was assigned to two different devices, resulting in an IP address conflict warning for the devices. I wanted to change the IP address of one device manually to resolve the issue but could not find where to do it. So, I added a new IP address to be reversed and assigned it to one of the devices with the conflicting IP address. However, the IP address of the device was not changed when I checked in the "Attached Devices" after refreshing the list. The two devices still shared the same IP address. I powered cycle the router, still got the same result.
My questions are:
1. How come the router still assigns the same IP address to two devices even though I reserve the IP address for a specific device? Is it a firmware malfunction?
2. Can I change the IP address of a device manually to resolve the conflicting IP address issue?

Re: conflict IP address after power failure
What are these devices you reserved IPs for?
Any of them phones or pads?
Be sure to disable any MAC Address randomizers on phones and pads while at home:

Not phone or pad. The devices are Synology NAS and YAMAHA receiver.

Re: conflict IP address after power failure
Still have the question of why the router still assigns the same reserved address to different devices.

Re: conflict IP address after power failure
Ok. Something you might do for those two devcies Setup a static IP address outside of the routers default IP address pool. Some devices like NAS and AVRs don't need much or any router management and recommend setting a static IP address on these devices. You'll need to change the routers IP address pool size. I recommend .100 to .200. Then you'll have room on either side of this pool for static IP addressed devices.
What I use for my NAS and AVR and others like printers and cameras.
Glad you got it working. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
