Hello,

I've been trying to add a new device to the security whitelist but when I add the MAC address and device name I get a message that says:-

"This hosts conflicts with the existing LAN hosts"

...or something very similar, and it doesn't allow me to add the new device. However it will allow me to add a device (that doesn't exist) with a slightly different bogus MAC.I have checked thoroughly and the MAC address of the device I am trying to add does not already exist.

I have already have a number of existing device entries in the whitelist and I have tried rebooting the router many times.

Any help would be appreciated!
