is there a way to setup the router to give the same ip address to my laptop?

Hi,

I used the DHCP reservation for a while and all was good until recently.

Recently, without any notice i found that i'm not able to access to one of my device using my reserved IP, after digging a bit i found that ALL my DHCP reservation list is gone, invisible, and all my devices start to get random IP address from the pool.

Now i tried to re-add the devices but the router bouncing back with errors, if i click on 'add' from the client IPs it gives me the following error message "Repeated Host name is invalid." but if i scroll down to the reserved list, it's empty.

Also, in other cases, different device, if i click 'Add' it adding it to the list, and then if i click 'save' it seems to save but when it closes the reservation screen i can see error on the top left side (see screenshot) and if i open back the reservation screen, my records does not saved.

Another problem, from the reservation screen if i click add on other devices but change the IP for example ip by default was 192.168.0.111 and i want to change it o 192.168.0.60 i get error 'ipError' and then 'IP Reservation should only work inside the DHCP pool.' but the IP is in the pool.

What next? the reservation is completely not working, and i really need it for some of my devices.

I don't want to use Static IP.

Thank you for your help

I am attempting to leverage the DHCP reservation functionality in the CODA modem router. However, it does not seem to be working.
Step 1. I go to Basic -> LAN Setup -> DHCP Reservation.
Step 2. I find the device in question in the list, PC001 and I press the "Add" button.
Step 3. I scroll to the bottom of the list and I see the device now PC001 added to the reservation list.
Step 4. I give the device a friend name Mine (making sure that it is unique).
Step 5. I update the IP address to the one I want it to have (making sure that it does not conflict with an existing device, that it is within the DHCP range and on a valid subnet).
Step 6. I press the "Save changes".
Step 7. I wait for the modem to reboot.
Step 8. Release the IP address on PC001 and power cycle it for good measure.
When PC001 reboots, it shows the original address and not the reserved one. When I log back into the CODA modem/router
Step 1. I go to Basic -> Lan Setup -> Connected Devices and push the "Show" button
Step 2. I find PC001 (Mine) in the list.
Step 3. I see that the wrong IP address is assigned to PC001 (Mine) even though under the "Type" heading it shows "DHCP-Reserved"
Step 4. I return to the "DHCP Reservation" menu lookup PC001 (Mine) to see if the desired IP address is was correctly saved.
Step 5. I reduced the DHCP Lease time to 30 minutes.
Step 6. I wait at least 30 minutes and released the IP address once again on PC001 (Mine).
Step 7. Then I power cycle it and I am still not getting the desired IP address.
I have tried the following procedure with multiple devices (desktop, laptops, IoT devices, etc.) and it does not seem to be working with any of them. It does seem to eventual work if I shutdown the modem for at approximately 10 minutes and shut down the devices and only turn them on after the modem has finished rebooting.
Has anyone had a similar issue?
