DHCP Manually assigned IP not used

[Jeje2]

Just noticed that a device I have manually assigned in the Manually Assigned IP around the DHCP list isn't using the assigned IP, even though MAC address is right...

Looked at assigned DHCP IP addresses under system log and noticed this one device on "wrong" IP-address compared to what I have specified in the DHCP manual list...
So now I'm confused - why isn't it using the assigned IP?
(And this MAC and IP binding configuration I have done weeks ago...)
Using RT-BE86U with newest asuswrt FW v. 3.0.0.6.102_39112

why isn't it using the assigned IP?

Funny, I think this has happened to all of us at some stage.
IIRC, it should get the manual assigment first, then DHCPs are assigned later.

So, quick answer, without looking at any logs, a couple of reasons might be:

1. The device has a static IP assigned on the Device (but you would probably remember this; nonethless, maybe check)?
2. You assigned the device its manual IP some time ago, after it already had got a DHCP assigned address. Since then, have you restarted (a) the device and (b) the Router ?
   
   [or failing (b), that at least restarted dnsmasq? From the SSH CMD Line: service restart_dnsmasq ] ?
   
   
3. Even though MAC address is correct, sometimes it isn't i.e. that errant 0 vs O really gets you. Pays to double check?
