I'm trying to assign fixed IP addresses to some of the devices connected to my Orbi RBR50 router. I'm using version V2.1.2.18 of the firmware. I think I should be able to set this up under "ADVANCED" - "Setup" - "LAN Setup" - "Address Reservation". When I click "Add" it goes to a new screen containing an "Address Reservation Table". In the table I can select the device I want to give a fixed IP address. But when I do that and I click "Add" (at the top), I keep getting this error message: "400 Bad Request. This server does not support the operation requested by your client." Is this an error in the firmware or am I making a mistake somewhere?

Hi wchp, thank you for your reply. I didn't hard reset the router and the sattelite after I updated to 2.1.2.18. Should I do that? And will that not delete all my settings? I tried to assign the IP address which was given to the device by the router. I tried limiting the scope of DHCP but that didn't make a difference - I still get the same error message.

Hard reset on the satellites and router will delete all of your settings. Do NOT restore a backup from a previous version of firmware.
The idea is to wipe any settings that may cause anomalies in the new version of firmware.
Yes... it's kind of a pain but the only way you can be sure you are working with a clean slate.
I just tested adding a DHCP reservation using both the table and by manually entering the MAC, IP and Device name. on 2.1.2.18 again and both worked as expected.

Thanks again for your message - really helpful. The hard reset frightens me a little because I am not too sure if I wlll be able to put all my settings back correctly... I did find out something that may or may not be relevant: the procedure works fine on other devices connected to my network (both wireleless and ethernet connected), just not with one specific device: a thermostat. Could it be that this device refuses a fixed IP address or am I making things up now?

Thanks FURRYe38, that worked for me! I checked and the name of the device was 22 characters. When I shortenend the name (under the 'Address Reservation Table' appear three fields when you select a device from the list, the third one lets you change the name of the device) it worked fine! I also checked the names of the devices which I managed to add earlier and they were all shorter than 20 characters.
