I have issues with DHCP reservation. Whenever I add the new reservation the router rejects it because some my existing reservations "already in use". It looks like a UI/FW bug. Any ideas?
What happens if you reserve the IP address the device already has, via the device listed in the initial Advanced mode section? I can't say I have noticed any problems, but a screenshot of what you are trying to do would make it easier for me to see if I can replicate your problem.

I don't reuse IP. I add the new reservation, but the UI shows a error on one of the previously existing reservations. It says "IP already in use". Of course it is but I don't change it I just add something new.
What firmware is your Sagemcom running, you have only quoted the hardware revision?
To reuse a previously reserved IP address, the device that used that address previously must not have tried to connect to the router for more than 24 hours (default DHCP Lease time is 1 day). Once this timer has expired, the IP address should be available again. If you do not want to wait that long, reboot the router.
